UNI-REZ™ 2532

1 of 47 products in this brand
UNI-REZ 2532 (formerly UNI-REZ E3525) thermoplastic polyamide resin is designed to impart a high degree of thixotropy to alkyd resins. Thixotropy can be achieved by reacting UNI-REZ 2532 with the alkyd resin at temperatures between 210-230°C. UNI-REZ 2532 can be easily processed and achieves its clear point on dilution before attainment of maximum thixotropy. UNI-REZ 2532 forms very strong and rigid thixotropic gels that are resistant to high levels of polar solvents.
