●F520 Polyaspartic Ester Resin, is a solvent-free coating materials and a reactive partner for polyisocyanates. It’s the same model as Bayer Desmophen NH1520, formulate high-solids, two-component polyurethane topcoats and solvent-free coating materials.
● F520 Polayspartic Ester Resin can also react with –NCO functional HDI trimmer from which a longer gelling time and excellent yellow resistance can be achieved. Longer gelling time can also be obtained when mixing with F420 and F524 to achieve a pure Polyaspartic polyurea coating with high build and fast dry two pack coating system F520 Polayspartic Ester Resin is also compatible with other hydroxyl-functional resin e.g acrylic, alkyd. It is 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
