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.”
Typical Properties for Crystic 15PA S & B
When tested in accordance with the appropriate BS OR BS EN ISO Method
| Viscosity at 250C | Thixotropic | Thixotropic | |
|---|---|---|---|
| Volatile Content | % | 40 | 30 |
| Geltime at | Minutes | 7 | 11 |
| 250C (using 2% Butanox M50) | |||
| Stability in dark at 200C | Months | 3 | 3 |
Crystic Skincoat VE679PA
An easy to use Vinyl ester / DCPD skincoat which significantly reduces the occurrence of fibre print through.
Crystic VE679PA greatly enhances surface finish on mouldings.
Typical Liquid Properties
| Appearance | Red / brown | |
|---|---|---|
| Viscosity at 250C 4500 sec-1 | Poise | 2.3 |
| Viscosity at 250C 37.35 sec-1 | Poise | 3.5 |
| Specific Gravity @ 250C | 1.065 | |
| Stability at 250C | Months | 3 |
| Geltime at 250C using 2% Butanox LPT | Minutes | 18 |
| Geltime at 250C using 2% Butanox M50 | Minutes | 23 |
- Suitable for continuous processes such as filament winding and pultrusion
- Good tensile properties for controlled processing
- Creates a chemical barrier and surface finish
RTR 4000PA Excel
Crystic RTR 4000PA Excel is a new, improved rapid tooling resin which incorporates better handling, lower viscosity, improved shrinkage control and ease of use.
For the manufacture of high quality, low profile mould making applications.
