Materials & resins
We select the corrosion barrier and structural laminate for each service — vinyl ester, isophthalic and Dow Derakane™ systems — matched to the chemistry, temperature and abrasion of your process. Common choices and datasheets:
Derakane 411 — general corrosion · Derakane 470HT — high temperature · Derakane 510A — oxidizing / chlorine · Derakane 8084 — abrasion / elastomer-modified · AROPOL 7334T — isophthalic
