● F524 Polyspartic Ester Resin is an amine-functional solvent free resin. F524 Polyspartic Ester Resin is an aspartic ester polymer as reactive partner for polyisocyanates.
● As a similar product of F420, it can offer longer gelling time than F420 but less gelling time than F520. It provide higher flexibility than F420. For pure aspartic system, a blend of F420,F524 and F520 is recommended.F524 is also widely used in protective /floor / elastic/weather resistant coating, waterproof, etc.
● Main Feature
1. High solid content with low viscosity
2. Faster curing time in aliphatic system
3. Offering excellent physical properties like high hardness, flexibility, elongation(400%), tear and tensile strength(25MPa).
4. Great weather and saline water resistance
5. Cost efficiency
Ⅲ Quality standard
