F520

Technical Datasheet | Supplied by DKSH
F520 supplied by DKSH is an amine-functional aspartic ester resin. It is a solvent-free, low viscosity coating material and a reactive partner for polyisocyanates. High-solids, two-component polyurethane topcoats can be formulated using this resin. It offers a faster curing time in aliphatic systems. It 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 F-420 and F-524 to achieve a pure aspartic polyurea coating with high build and fast dry two pack coating system. It provides excellent hardness, flexibility, elongation (400%), tear and tensile strength (25 MPa). It is resistant to weather and saline water. F-520 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. F520 has a shelf life of 12 months when stored at 0-40°C.
