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
