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
