URETHANE SYSTEM

POLYOL 30211
ISOCYANATE 40008

DESCRIPTION

30211/40008 Urethane Potting System is a black, polybutadiene based, flexible, flame retardant urethane that has a low mixed viscosity and long gel time.

System Components:
30211 Part A with 40008 Part B.

USE

Designed for ambient cured applications requiring good hydrolytic stability, flame retardancy and flexibility. The moderate initial viscosity and long gel time make this a viable system for automated production.
