JONCRYL 922
JONCRYL 922
JONCRYL® 922 is an innovative acrylic oligomer for high solids polyurethane coatings. It employs a novel technology, which makes this polyol more reactive with isocyanate crosslinking agents. The result is the ability to formulate fast drying urethane coatings with quick dry times and a practical pot life. High solids coatings for maintenance, transportation, and other applications can be formulated from 2.3 to 3.8 pounds per gallon of VOC.
This product is supplied in n-Butyl acetate for use in areas where odor is a concern. It is also available in MAK as JONCRYLÂ 920. JONCRYLÂ 922 should be considered as a candidate for high performance, maintenance, and transportation coatings as a replacement for conventional solids urethane finishes.
JONCRYL 922 is recommended for applications such as:
- Interior/exterior general metal coating applications
- Automotive refinish coating applications
Features & Benefits
- Very low VOC
