Dendrimer greatly improves powder polyester coating performance.
There’s shrinkage cavity during curing of powder polyester coating, improving leveling of powder has good application value. Dendrimer modified by crystal polar polymer has high Tg, the void space and hyperbranched structure can overcome above problems. Complex viscosity of powder coating with dendrimer was decreased to 20%-50% of standard sample, contact angle was lowered from 100°to 80°, surface tension was increased, thus leveling time was more and performance was better, meanwhile no negative effect on adhesion, pencil hardness, impact strength, flexibility, luster etc. Weihai CY Dendrimer Technology-Professional Manufacturer for low cost dendritic polymers.-The newest 4th class polymers.
