JONCRYL® 920 is an innovative acrylic oligomer for high solids polyurethane coatings, which features fast cure with a practical pot life. High solids coatings that are as low as 2.3 pounds per gallon of VOC can be formulated to spray by conventional or airless equipment. It displays outstanding viscosity characteristics without the addition of low molecular weight reactive diluents. JONCRYL 920 should be considered as a candidate for high performance maintenance and transportation coatings as a replacement for conventional solids urethane finishes.

JONCRYL 920 is recommended for applications such as:

• Interior/exterior general metal industrial coating applications
• Automotive refinish applications

Is odor a concern? See JONCRYL 922 is supplied in n-Butyl acetate.

Features & Benefits

• Fast dry time
• Practical pot life
• Utility as a modifier
• Very good gloss development
• Supplied in n-Butyl acetate
• Excellent for low VOC systems

Performance Data

Cure/Dry Characteristics

The following graph illustrates the dry times/cure rates of a typical white topcoat formula based on JONCRYL® 920. Due to the increased reactivity of this product, catalysts are not normally used. If increased reactivity is desired, typical urethane catalysts such as dibutyltin dilaurate can be used. If a catalyst is used, the dry time and the pot life will both be reduced. The pot life of this system will normally be between 4 – 6 hours when pot life is defined as the time to double an initial viscosity of 250 cP.
