Chopped Strand Mat (Emulsion Bonded) E20

Chopped Strand Mat (Emulsion Bonded) E20

E6CR E20 Emulsion Chopped Strand Mat is made of randomly distributed chopped E6CR glass strands held together by an emulsion binder.

E6CR E20 is suitable to reinforce unsaturated polyester, vinyl ester,epoxy and phenolic resins.

E6CR E20 is designed mainly for use in the hand lay-up process and also suitable for use in filament winding and continuous laminating processes. Its end-use applications include boats, bath equipment, automotive parts, chemical corrosion resistant pipes, tanks, cooling towers and building components.

Glass Type:E6-CR

Product Features

  • Good conformability
  • Good wet-through and fast wet-out in resins, rapid air lease, reducing rolling out time and increasing productivity
  • Low resin consumption
  • High mechanical strength of parts
  • Superior acid corrosion resistance

Product Specifications


Unless otherwise specified, powder chopped strand mats should be stored in a cool, dry, water-proof area. It is recommended that the room temperature and humidity be always maintained at 15°C to 35°C and 35% to 65% respectively.


Each Emulsion Chopped Strand Mat is wound onto a paper tube which has an inside diameter of 90mm. The roll outside diameter is approximately 265mm. Each roll is wrapped up in plastic film and then packed in a cardboard box. The rolls are stacked horizontally or vertically onto pallets. All pallets are stretch wrapped and strapped to maintain stability during transport.

Hand Lay-up Process

Hand Lay-up is an open molding process.

The reinforcement, in form of fiberglass strands, mat, or woven roving, is first laid into a mold which has been coated with a release agent and a gel coat. Then a resin mix is applied by hand, using a brush or spray gun. A roller is then used to ensure uniform impregnation, complete wet-out and removal of any trapped air bubbles.
