Chopped Strand Mat: 1 1/2 ounce

1.5 oz/sq ft, 38" & 50" Wide, 0.045" Thick Chopped Strand Mat is most frequently used with polyester resin to quickly build thickness for parts and between layers of fabric for building molds. It can be used alone or in conjunction with fiberglass fabrics, or woven roving, in larger fabrications. Fabricators generally tear apart Chopped Strand Mat, rather than cut it. This maintains the length of fibers along the torn edge, which create stronger bonds with subsequent layers. Chopped Strand Mat contains a binder which holds strands together, but prevents proper bonding with any epoxy resins. PLEASE NOTE: It is only compatible with polyester or vinyl ester resins. For convenience, mat is also sold in 4-inch-wide tape form (#492). For 38-inch, typical full roll length is 80 yards. For 50-inch, typical full roll length is 87 yards.
