F520 NH1520 No VOC Polyaspartic

F520 NH1520 No VOC Polyaspartic

1)Description:

Polyaspartic is a two component, high solids, aliphatic Polyaspartic. This unique new resin chemistry has provided the raw materials to formulate this coating that gives the desirable properties of polyester-polyurethane materials with shorter cure time and less film thickness limitations. Polyaspartic is a low viscosity, easy to handle product that gives very high gloss finishes that are both hard and abrasion resistant. This material releases soil easily and has excellent resistance to a broad range of chemicals. Unlike conventional polyurea materials, Polyaspartic has enough work time to be applied by brush and roller. It is very rapid curing and can be returned to full service in 24 hours. For exterior applications, a UV stabilizer package is incorporated to ensure long-term gloss retention and resistance to yellowing.

2) Chemical formula and molecular weight

● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin, N,N'-[methylenebis(2-methyl-4,1-cyclohexanediyl)]bis-, 1,1',4,4'-tetraethyl ester

● ELINCS No.: 412-060-9

● CAS No.: 136210-32-7

3) Properties and application

●FEISPARTIC F520 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH1520, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials.

● FEISPARTIC F520 can also react with –NCO functional HDI trimmer from which a longer gelling time and excellent yellow resistance can be achieved. when mixing with FEISPARTIC F420, longer gelling time can also be obtained. FEISPARTIC F520 is also compatible with other hydroxyl-functional resin such as acrylic, alkyd resin. It is widely applied on formulating variety of protective coatings.

4) 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 weathering and saline water resistance

5) Quality standard

6) Package and storage

● 200Kgs/Drum, 4Drums/pallets, 80Drums/container or 1Ton/IBC tank.

●FEISPARTIC F520 resin must be stored in tightly sealed containers to prevent from contacting with moisture. Recommended storage temperatures are 0°-40°C (32°-104°F). The shelf life of FEISPARTIC F520 is 12 months when stored in closed original containers at 77°F (25°C).
