F220 Polyaspartic Ester Resin
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.
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin, N,N'-[2-methy-1,5-pentanediyl)]bis-, 1,1',4,4'-tetraethyl Ester
● ELINCS No.: 433-260-2
● CAS No.: 168253-59-6
Ⅱ Properties and application
● FEISPARTIC F220 is reactive partner for polyisocyanates, is a solvent free amine-functional resin. FEISPARTIC F220 is the same model as NH1220,could be used for the formulation of tough but flexible, lightfast and highly reactive two-component polyurethane spray coatings.
●FEISPARTIC F220 can be applied in SPUA (spraying elastomeric polyurea) R component as chain extender and main resin,FEISPARTIC F220 can be used to formulate anti-corrosion coatings for the protection of steel structures, oil pipelines, bubble landscape, concrete waterproofing materials.
● Main Feature
