Used for awkward edges etc before main laminate is laid down.
Commonly used in model boat making.
For every metre from the roll you should use between 450g – 550g of resin. Chopped Strand Matting can be used as a single layer or a multi layered laminate. The Fibres are laid randomly across each other and held together by a binder, in this case an Emulsion binder.
There are two types of binder, Emulsion and Powder: Emulsion for Polyester Resin or Vinyl ester use, and powder bound for use exclusively with epoxy resins. Once the Matt has been brushed with a Polyester Resin the binder will slowly break down and thus enable the material to easily conform to shapes and be consolidated into a laminate.
Generally you would use 1.5 to 2.5 Resin to Glass ratio, so for every Kg of Matt you would use between 1.5kg to 2.5kg of Resin.
