URETHANE POTTING SYSTEM

POLYOL 30207
ISOCYANATE 40002


DESCRIPTION

30207/40002 Urethane Potting System is a low cost, black, filled, flexible, urethane that has a low mixed viscosity and moderate gel time.

System Components:
30207 Part A with 40002 Part B.

USE

Designed for ambient cured applications requiring good hydrolytic stability and flow. The low initial viscosity and moderate gel time make this a viable system for automated production.
