Fiberglass Mat, also known as Chopped Strand Mat or CSM for short, is a non-woven material typically used for laminate build-up and repair work. It consists of glass fibers laid randomly across each other and held together by a styrene binder.

Polyester is the preferred resin for wetting out this form of glass fiber material as it readily dissolves the styrene bonding agent.

Offered in various weights per square foot. The lightest version, veil mat, is used commonly as a finishing layer to mask any print-thru in a laminate schedule. This particular veil mat uses longer, thinner fibers than heavier mat weights also offered here. Think angel hair pasta to spaghetti fibers. Coarser, heavier mat is commonly used for bulk, random axis strength buildup and is also an excellent initial layer when bonding repair work.
