Epoxy floor coating diluent is a reactive additive that cuts viscosity so the mixed resin self-levels and wets the substrate. Yolatech supplies three types: BGE YLD-9004, cardanol glycidyl ether YLD-9006, and cardanol diglycidyl ether YLD-9014. They crosslink into the film rather than evaporating. What a Reactive Diluent Actually Does A reactive diluent carries an epoxy group, so it crosslinks into the network instead of evaporating. That separates it from xylene or acetone, which flash off, leave the film thinner than dosed, and contribute to shrinkage. In a floor coating the goal is usually a wet film that levels itself, releases air quickly, and still cures hard enough to take fork-lift traffic. Three Epoxy Floor Coating Diluent Types Compared Product CAS EEW (g/eq) Viscosity @25 °C (mPa·s) YLD-9004A (BGE)2426-08-6147–157≤2 YLD-9004B (BGE)2426-08-6188–205≤3 YLD-9006 (cardanol)—355–50030–50 YLD-9014 (cardanol)—290–3501,000–3,000 BGE is the cheapest way to drop viscosity and the obvious pick for solvent-free self-levelling screeds. It also carries the strongest odour of the three, and at high loading it pulls heat deflection temperature down. Cardanol grades behave differently. YLD-9006 keeps a low viscosity of 30–50 mPa·s while adding flexibility, water resistance, and better adhesion — useful where the slab moves or the floor sees wash-down. YLD-9014 is thicker at 1,000–3,000 mPa·s and is normally used to toughen rather than to thin. Typical Dosage For a standard bisphenol A floor resin, BGE is dosed at 5–15 phr. Push past 20 phr and you feel it in cure speed and hardness. Cardanol ethers usually run 10–30 phr because their higher EEW means less network disruption per unit weight. Because YLD-9006 and YLD-9014 carry reactive epoxy groups, they must be counted into the stoichiometric calculation against your hardener. Diluent added without adjusting hardener leaves unreacted resin and a soft film. Confirm the exact figure against our TDS before scaling up. Where Each Type Fits Pick BGE for cost-driven primer and mid-coat formulations. Pick YLD-9006 for topcoats in food plants, car parks, and chemical stores where flexibility and water resistance matter more than price. For wash-down areas that see thermal shock, an epoxy floor coating diluent with cardanol chemistry holds up better than a straight BGE grade. Butyl glycidyl ether BGE YLD-9004 — full specification, and cardanol glycidyl ethers YLD-9006. Tell us your target viscosity and cure schedule and we will match the diluent to it.

  • Low Stress Epoxy Resin for Electronic Encapsulation

    Low Stress Epoxy Resin for Electronic Encapsulation

    Low stress epoxy resin for electronic encapsulation is a formulation answer to one failure mode: package cracking at solder reflow. The cause is a thermal mismatch, because the resin, copper, and silicon expand at different rates. Yolatech meets this with the DOPO-HQ modified phenolic epoxy series. Why Low Stress Matters in Encapsulation A potting compound does not fail from mechanical load. It fails because it is restrained. The resin wants to shrink on cooling, the die does not move with it, and the mismatch shows up as warpage, interfacial delamination, or a crack that starts at the corner of the silicon. Two material properties drive that stress: coefficient of thermal expansion and water absorption. Water matters because absorbed moisture flashes to steam during reflow at 260 °C, and the resulting pressure is what pops the package. DOPO-HQ modified phenolic epoxy attacks both. Its densely crosslinked aromatic backbone keeps expansion low, and the polar groups responsible for moisture uptake are fewer than in conventional bisphenol A systems.

    Yolatech at Middle East Coatings Show 2026 in Dubai

    Middle East Coatings Show 2026 is the MENA region's largest coatings exhibition, held 28 to 30 September 2026 in Dubai. It ran at the Dubai Exhibition Centre in Expo City Dubai, where Yolatech showed epoxy resins, curing agents and reactive diluents at the joint booth NA90. The show runs biennially. What Middle East Coatings Show 2026 Covered The Middle East Coatings Show has run for more than 30 years and is the only trade event in MENA that covers the full coatings supply chain rather than finished paint alone. The 2026 edition was moved from its original April slot to September, a change the organiser announced in March to smooth travel and logistics for regional buyers. Chemicals and raw materials, laboratory and packaging equipment, testing and measuring equipment, and plant and machinery share the same halls. A formulator can compare a base resin, the hardener that crosslinks it and the equipment that dispenses it without leaving the venue. A presentation programme called ChemTalks ran alongside the stands. Middle East Coatings Show 2026 Detail Cycle Biennial, over 30 years in the coatings industry Dates 28 to 30 September 2026 Venue Dubai Exhibition Centre (North Halls), Expo City Dubai Organiser The Coatings Group, dmg events Reported scale 5,000+ attendees, 350+ exhibiting brands, 24+ countries Exhibition space Over 15,000 sq m Product sectors Chemicals and raw materials, laboratory and packaging equipment, testing and measuring equipment, plant and machinery What Yolatech Brought to the Joint Booth NA90 The stand was a joint booth run with the group's other chemical brands, so a visitor could compare our epoxy resins, hardeners and diluents against the adjacent product families without walking the hall. Our panels carried the three groups a coatings formulator buys in sequence: epoxy resin, curing agent and reactive diluent. Every grade number was printed on the panel, so visitors could read a shortlist off the wall and photograph it instead of waiting for a datasheet. Resins were split three ways. Basic covered bisphenol A and bisphenol F in liquid and solid form. Modified covered urethane, rubber and dimer acid grades plus DOPO flame-retardant types. Specialty covered novolac, cycloaliphatic, hydrogenated BPA and naphthalene types. Hardeners ran from polyetheramine and modified aliphatic amines through polyamide and aromatic amine to anhydride and imidazole. Diluents were separated into monofunctional, bifunctional and polyfunctional reactive types.

High heat, sand and ultraviolet light push three requirements back to the formulation: colour and gloss retention outdoors, corrosion resistance on steel, and heat resistance for pipe and plant coatings. Viscosity control drew the most questions. Solvent-free and high-solids systems need a reactive diluent that lowers viscosity without the odour and slow cure that older grades carry. AGE (C12-C14) at 4 to 10 mPa.s was the grade most visitors wrote down, usually against a novolac or bisphenol A base for a tank, pipe or floor coating. Our page on epoxy resin coatings sets out how resin, hardener and diluent are matched for these systems. Hardener ratio came second. Visitors arrived with a base resin already on their bench and wanted the amine value and mixing ratio for it, which is a data question rather than a sales question. Polyetheramine D-230 and MHHPA anhydride came up in the same conversations, usually where a room-temperature cure was too slow for the application. Joint booth NA90 at the Dubai Exhibition Centre: the Yolatech panel listing epoxy resin, hardener and reactive diluent grades. Samples, TDS and the Next Step Samples of the grades shown at Middle East Coatings Show 2026 are available for laboratory evaluation. Each grade ships with its TDS, and the COA travels with the lot, so a formulator can check EEW, viscosity or amine value against the certificate before scale-up. The working order is the one the panels followed: resin family first, then hardener, then diluent. Liquid bisphenol A epoxy resin and solid bisphenol A epoxy resin are the usual starting points, with solvent-cut grades where a working viscosity is needed straight from the drum. Novolac epoxy resin and DOPO modified phenolic epoxy resin cover the heat-resistant and flame-retardant ends of the range. Send a target EEW, viscosity or amine value and we will match it against the nearest production grade rather than the nearest listed one.

  • Structural Adhesive Curing Agent: HTDA, MXDA or DACH?

    Structural Adhesive Curing Agent: HTDA, MXDA or DACH?

    A structural adhesive curing agent is the component that decides whether a bonded joint holds at 80 °C or creeps apart. Yolatech supplies three amine types for that job: HTDA, MXDA, and DACH. Each one trades cure speed against heat resistance and pot life. All three cure fully at room temperature. What a Structural Adhesive Curing Agent Must Deliver Three things, in this order: room-temperature cure, high glass transition temperature in the cured network, and a workable pot life. Those pull against each other. Fast cure usually means short pot life, and high Tg usually means brittle. Alicyclic amines resolve the conflict better than aliphatic ones. The ring adds stiffness for heat resistance without the yellowing that aromatic amines bring, and the saturated backbone resists oxidation over time. Three Grades Compared Product CAS Purity (%) Key figure HTDA13897-55-7≥99.0Amine value 820–900 mg KOH/g MXDA1477-55-0≥99.0Water ≤0.50 % DACH694-83-7≥99.0AHEW 28.5 g/eq HTDA is a cis/trans isomer mixture that stays liquid at room temperature. Its moisture content is capped at 0.1 %, which is tighter than MXDA at 0.5 % — that matters in an adhesive because water competes with the amine for epoxy groups and leaves a weaker joint. MXDA is a xylylenediamine with an aromatic ring and aliphatic amine groups. It cures at room temperature and is widely used where you need faster development of strength. It yellows on prolonged air exposure, so it suits pigmented or hidden bond lines more than clear ones. DACH is the reference point for calculations because its AHEW is published. At 28.5 g/eq against a 185 g/eq resin, the stoichiometric load is 28.5 ÷ 185 × 100 = 15.4 phr. Working Out Your Dosage Amine dosage always follows amine hydrogen equivalent weight divided by epoxy equivalent weight, times one hundred. Get that number first, then adjust down 5–10 % if the joint needs more flexibility. Running below stoichiometric leaves epoxy groups unreacted; running far above it leaves free amine that attracts moisture. Both show up as a joint that fails in humid service. Confirm the final figure against our TDS before production. Which One to Pick For a general structural adhesive at room temperature, start with DACH — its published AHEW makes formulation predictable. Move to HTDA when the joint sees heat or chemical exposure, and to MXDA when cure speed matters more than colour stability. Whichever structural adhesive curing agent you land on, calculate the ratio before you scale the batch. HTDA CAS 13897-55-7 — full specification, DACH CAS 694-83-7 with AHEW data, and MXDA CAS 1477-55-0. Tell us your cure temperature and target Tg and we will narrow the choice down.
