Series 270


Generic Type

Polyamine Epoxy

Common Usage

A high-performance, fiberglass-reinforced wall coating for protection against acids, alkalis and physical abuse. Stranlok’s 100% solids epoxy technology is solventless and VOC compliant, making Stranlok virtually odorless and permitting application in occupied facilities. Its accelerated curing schedule and installation process mean faster return-to-service times. A unique blend of two types of premixed reinforcing fibers allows Stranlok to be spray or trowel applied up to 40 mils. The integrity of the interlocking fibers allows the surface to withstand daily high-pressure steam cleaning. In addition to this high tolerance to “thermal shock,” Stranlok also features broad chemical, impact and abrasion resistance.
