Coremat


Coremat® is a polyester nonwoven that contains microspheres. It is used as a thin core (bulker mat) or print blocker (liner) in fiber-reinforced laminates, manufactured in Hand Lay-Up or Spray-Up processes. Coremat should always be thoroughly impregnated with resin. The microspheres in Coremat prevent excessive resin uptake.

The most important reasons to use Coremat are:

  • Weight saving
  • Resin and glass saving
  • Stiffness increase
  • Fast thickness build-up
  • Excellent surface finish
  • Width: 39"
  • Weight: 1.8oz/sq yd
  • Thickness: 2mm
