Introduction:

Coremat is a non-woven polyester that contains microspheres and is used build laminate bulk and block print-through in composite laminates . Produced in a variety of widths and thicknesses, core mat is also known as a laminate bulker or a core fabric. It is used to build laminate thickness (increasing stiffness) and to isolate laminate shrinkage from the cosmetic gel coat surface. In applications requiring good cosmetics, core mat is used to improve surface quality; particularly with darker, more revealing gel coats. Popular in the marine and recreational vehicle industries where surface finish is critical, core mat wets out quickly and is conformable to fit mold contours.
Coremat  is very soft and pliable when it is wet is suitable for use within complicated shapes or molds.

The cost effective solution for open mould processes
Is used as core material and/or print blocker
Is a polyester nonwoven and compatible with all regular
types of resins, including Polyester, Vinylester, Phenolic and Epoxy
Is suitable for hand lay-up and spray-up processes
