Nonylphenol has long been used in epoxy resin systems as a functional aid to promote dilution. However, in recent years, with increasing health awareness and stricter environmental regulations, the use of nonylphenol has become increasingly restricted.

Nanjing Youlai's Styrenated Phenol MSP-250 serves as an epoxy resin modifier. In addition to its ideal chemical properties, it meets the demands of environmental regulations.

Typical Data

• Product Name: Styrenated Phenol
• Grade: MSP-250
• Appearance: Liquid
• Color (APHA): <200
• Viscosity (cps/25°C): 300~800
• Hydroxyl Value (mg KOH/g): 230~260

Performance Features

As an epoxy resin modifier, MSP-250 is a clear, low-viscosity liquid. When added to the curing agent component, it accelerates the curing speed and improves the water resistance, anti-whitening properties, scratch resistance, abrasion resistance, hardness, and leveling performance of the cured product.

MSP-250 exhibits color stability under both long-term and high-temperature conditions. Comparison of color performance between MSP-250 and Nonylphenol when mixed with curing agents:

Within 1 week at room temperature: No significant difference observed.

Within 3 days at 60°C: MSP-250 demonstrates superior color stability compared to Nonylphenol.

Within 1 week at 60°C: MSP-250 demonstrates superior color stability compared to Nonylphenol.

Application Area

• Epoxy Coatings & Heavy-duty Anti-corrosion Coatings: Acts as a plasticizer, diluent, and accelerator.
• Craft & Jewelry Adhesives: Offers excellent transparency, abrasion resistance, and adhesion.
• Electronics & Electrical: Suitable for potting, varnishes, industrial adhesives, and LED encapsulation.
• Automotive Sealants: Improves bonding for doors and headliners, providing waterproofing and rust prevention for internal and external panels.

Civil Engineering & Construction: Applicable for crack sealing, crack injection, carbon fiber reinforcement, and steel reinforcement.
