F220=NH1220 POLYASPARTIC RESIN
F220 Polyaspartic Ester Resin
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. Relative humidity can have a dramatic change to dry time and pot life. Water/moisture in your coating system will have a catalytic effort on the cure response and pot life of final coatings. The addition of moisture from 0.10% to 0.20% can shorten the dry time in half.
Polayspartic polyurea technology is a core technology in our company. We have established a lab research base since 2004, with a strong R&D team consisting of 40 engineers. Now our polyaspartic polyurea materials have been applied on anti-corrosion, waterproof, flooring, construction coatings etc. We also can provide unique guide formulation to manufacturers based on their specified requirements.
