F2872 NH2872 Polyaspartic Resin Weather Resistance
Polyaspartic polyurea has many obvious advantages including environmental protection, low VOC, energy saving and emission reduction, weather resistance, high temperature resistance, wear resistance, high thickness of one spraying film, can reduce the process, reduce labor costs and so on.
At present, polyaspartic polyurea in the field of coating is used in construction machinery (automobile), containers, fan blades, Marine heavy corrosion, high-end industrial and commercial floor coatings;
In the adhesive field, it is mainly used in sealant, stone adhesive, electronic adhesive, film circuit packaging adhesive and other high-end fields; In the field of waterproof materials, it is mainly used in hydroelectric DAMS, water parks, building waterproof repair materials and other fields; In the field of structural materials, it is applied to curling track, artificial ice skating rink and other structural materials.
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
Ⅱ Properties and application
●FEISPARTIC F2872 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH2872 XP, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials
● FEISPARTIC F2872 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. F2872 could be applied to high solid anti-corrosion coating, high flexibility waterproofing coating, solvent free sealant and high rebound elasticity flooring coating.
1. Lower viscosity, can be reactive diluent in Polyaspartic system
2. Could be made into environmental coatings which has high solid content with low viscosity.
3. The reactivity is modest, could be used to extend working time
4. Providing excellent hardness, leveling property, gloss and touch feel to the coating
5. Paint film can offer excellent low temperature flexibility, waterproof and solvent resistance as well as acid and alkali resistance etc.
6. Can react with our elastic curing agent to make elastic materials with excellent mechanical properties of which elongation can reach to 400%.
