High Performance Matched

High Performance Matched

Tooling Systems From Scott Bader
Scott Bader has a new range of high performance matched tooling systems that are ideal for the following sectors

  • Land transport
  • Marine
  • Building
  • Industrial
  • Applications that require a superior gelcoat surface finish

Crystic Gelcoat 15PA (B) and (S)

Crystic VE679PA Skincoat& lightweight Reinforcement Construct the mold with either Crystic RTR 4000PA or Crystic 474 PA & your choice of reinforcement

CrysticGelcoat 15PA (B) & (S) CrysticGelcoat 15PA, both brush and spray,
represent the highest quality in tooling gelcoat manufacture.
A superior vinylester resin technology offers a premium finish with exceptional resistance to chemical attack and extremely long life cycles and multiple pulls.

“Very easy to spray with, covers nicely and no sagging. The degassing is perfect and no pinholes were found even after sanding the surface of the gel coat. But where it really out performs the competition is in achieving excellent resistance to print-through when vacuum bagging a 2 x 2 twill carbon fabric of 200 gm-2 with epoxy resin.”
