Top Coat Acrylic Polyols
Topcoat acrylic polyols are modified hydroxyl functional solid acrylic polyols recommended for specialty coating applications. It
can be cured at room temperature or under low-bake (70-80 ËšC) conditions with
aliphatic or aromatic isocyanates. The coatings exhibit good flow, gloss, gloss
retention, weather ability, and balanced mechanical properties.

APPLICATION GUIDELINES FOR ACRYLIC POLYOLS
Acrylic polyols can be used with an NCO/OH ratio of 1:1 acrylic polyol can be mixed with conventional hardeners like Desmodur N75 the recent description and with aliphatic hardeners. The mixing ratio and 100:20 can be followed. Alcoholic solvents must not be used as thinners. For faster curing, catalysts like DBTL can be added. However, the effect on pot life should be studied in such cases. Typical doses are 0.001% on resin solid.
Pot Life: Typically to one day if stored in proper
conditions. To enhance the catalysts and performance, the use of catalysts like dibutyltin laurate and UV absorbers is recommended.
RECOMMENDED APPLICATIONS
Acrylic polyols are used as a resin for formulating the
following coatings: Maintenance coatings for tanks, Plant equipment offshore
structures. Transport finishes for Trucks, Bases, and Ships.
