FEISPARTIC F321-Polyaspartic Resin=C321
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
Ⅱ Properties and application
● FEISPARTIC F321 is Aminofunctional co-reactant for polyisocyanates,is specifically designed to cure with standard HDI Trimer Isocyanates for industrial flooring applications. FEISPARTIC F321 is designed for applications where FEISPARTIC F221 does not offer sufficiently long working and open times.
● FEISPARTIC F321 preferred hardeners of choice are standard and low viscosity HDI trimer isocyanates for a range of industrial applications. Clear and pigmented topcoats and filled self-leveling systems based on FEISPARTIC F321 support high aesthetics, UV stability and rapid property development for fast return to service. FEISPARTIC F321 is free of solvents, alkyl phenol derivatives and benzyl alcohol.
● Main Feature
1. Zero VOC
2. Possesses extremely rapid hardness development and low temperature cure
3. Low color
4. Excellent UV stability
5. High aesthetic
6. Good abrasion resistance
