F220=NH1220 VOC FREE POLYASPARTIC RESIN
Shenzhen Feiyang Protech Corp., Ltd as a national high-tech leading polyaspartic polyurea researcher and manufacturer in China, has devoloped in this industry for more than 20 years and obtained over 20 patents in the field of polyaspartic polyurea. As a pioneer in China, we focus on researching the new technology and working on developing the unique products to achieve the excellent properties. Feiyang produces and upgrades Polyaspartic Ester Resins that equivalent with NH1420, NH1520, NH1220, NH2850XP, NH2872XP, C221, C321. Besides, we also produce elastic isocyanate (IPDI prepolymer and TDI/HMDI prepolymer) for elastic coating system.
Typical two-component coatings are not significantly affected by atmospheric humidity, however, changes in temperature do affect the cure response somewhat. ALI resins are affected by both, atmospheric humidity level and to a lesser degree by temperature.Changes in temperature can also affect pot life/dry time but not as dramatically as the addition of moisture. The combination of moisture and temperature should be considered when developing a formulation. Creating a ladder study to evaluate changes in relative humidity and temperature should be conducted to correctly predict dry times/pot life recommendations.
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
1. 100% high solid resin,
2. Faster drying time , Touch dry time with HDI is 5min,
