PPA - 7566 is a phenalkamine curing agent, specifically a Mannich base, made from distilled cashew nutshell liquid and polyamine. It features low viscosity and fast drying, making it ideal for developing VOC-compliant, solventless, or high-solids epoxy coating systems. PPA - 7566 offers excellent moisture resistance during curing and ensures rapid cure, even at low temperatures, similar to other phenalkamines.

Fine-Blend FB820 is a maleic anhydride grafted polyphenyl ether polymer designed as a compatibilizer for PPO/PA, PPO/HIPS, and PPO/HIPS/PA alloys. It enhances bonding strength, compatibility, and dispersion among components, improving tensile strength, impact resistance, and heat distortion temperature in reinforced polymer systems.

Ricobond 1731 is a viscous, brown liquid polymer composed of low molecular weight polybutadiene functionalized with maleic anhydride. It serves as an effective adhesion promoter and reactive compatibilizer, enhancing bonding in rubber compounds, adhesives, sealants, coatings, and encapsulants. Its maleic anhydride groups enable strong reactions with epoxy, amine, and hydroxyl groups, providing moisture resistance and compatibility with both polar and non-polar materials.

RICOBOND 1731 HS is a powdered maleinized polybutadiene dispersion combined with amorphous silica for easy handling. This free-flowing powder enhances adhesion in rubber compounds to metals and textiles, offering excellent reactivity and moisture resistance. It serves as a reactive toughener and compatibilizer, ideal for elastomers, coatings, adhesives, sealants, and electronics applications.
