E20 Emulsion Chopped Strand Mat is made of E-glass chopped strands randomly and evenly distributed and held together by a highly plasticizing emulsion binder.E20 is compatible with unsaturated polyester and vinyl ester resins.
E20 is a soft emulsion mat that offers easy hand tear and good fittability to molds.It is mainly used in hand lay-up and continuous laminating. The end uses include FRP vessels,bathtubs and FRP models.
