Gelcoat for Moulding
Red Raven Moulding Gelcoat is unwaxed and specifically formula to be used in moulds. If you are looking for a surfacing gelcoat (for repairs and easy sanding), you will need Red Raven Finishing Gelcoat (also known as Flowcoat).
This ISO White Polyester Moulding Gelcoat is specially formulated with thixotropic ingredients for increased viscosity and non-sagging properties. It incorporates pigments and contains additives for controlling flow-out, gel and cure times. Most high quality marine gelcoats use ISO/NPG (Isophthalic/Neopentyl Glychol) resins, which are higher quality polyesters. They are stronger and more durable than standard polyester resins (orthophthalic).
This Moulding Gelcoat can be applied by brush or roller. The gel time is typically 18 to 20 minutes. Standard polyester resin (orthophthalic) should not be used as a gelcoat. Standard resin does not have the same ingredients as gelcoat and has very little strength or coating properties on its own. Standard polyester resin must be used in conjunction with a fibreglass material to reinforce the resin for structural integrity.
