Bomar Oligomers® BRC-8430E

1 of 88 products in this brand

BRC-8430E is a reduced-functionality version of BRC-843S that provides improved flexiblity and reduced modulus compared with BRC-843S. The hydrophobic and temperature resistant backbone of BRC-8430E combined with the low modulus make BRC-8430E an excellent candidate for moisture resistant adhesives, coatings, and resins, as well as
formulations that need to pass autoclave or 85/85 testing.
