F525 Polyaspartic Ester Resin
Ⅰ Chemical formula and molecular weight
● Chemical Name: F525 Polyaspartic Polyurea Resin ● ELINCS No.: No defination, new substance
● CAS No.: No defination, new substance
Ⅱ Properties and application
●FEISPARTIC F525 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH1420, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials.
● FEISPARTIC F525 could serve as chain extender or R component in polyurea coating. It could also react with –NCO functional HDI trimmer from which longer gelling time and excellent yellow resistance can be achieved. Longer gelling time can also be obtained when reacting with MDI pre-polymer. Hybrid of polyurea and polyurethane can be achieved when FEISPARTIC F525 is blended with hydroxyl-functional resin such as acrylic, alkyd resin. FEISPARTIC F525 offers higher solid content and faster drying time than ordinary polyurethane. It is widely applied on formulating variety of protective coatings.
● Main Feature
1. High solid content with low viscosity 2. Moderate curing time in aliphatic system, providing applicable working time for Polyaspartic coating
3. High hardness with great anti-abrasion properties.
4. Providing good film build, leveling property and gloss 5. Excellent weathering resistance and flexibility in low temperature
6. Excellent waterproofing and solvent tolerance properties
7. Very good adhension to variety of substrates such as concrete,plastic,metal etc.
8. Excellent compatibility with most of the hydroxy acrylic resin
