Mould Resin P
- Hard elastic, good edge strength
- Excellent grinding and polishing properties
- Thixotropic (non-drip)
- Manufactured in a vacuum, so optimally free of air bubbles and homogeneous
This epoxy resin is coloured black for gel coats (applied thickness 0.5–1 mm) in-mould construction with high edge strength and good polishing properties.
In combination with Hardener EPH 161-P a post-curing (with the laminate backing) for approx. 15 hours at 60 °C is necessary.
It can be used as a top layer in conjunction with epoxy resin laminates and laminating ceramics. In contrast to resin and metal systems, the surfaces are polishable. The tooling gel coat is hard-elastic, i.e. non-brittle exhibits good edge strength, but is not resistant to styrene, which makes it unsuitable in conjunction with UP Pre-Gel.
Consumption: approx. 0.5–1 kg/m²
Hardener EPH 161-P
Mixing ratio: 100 : 17 parts by weight of resin to hardener
Processing time: 90 minutes (100 g batch size at 20 °C)
Gelling time: approx. 4 hours (1 mm application at 20 °C)
Curing: 24 hours at 23 °C, followed by post-curing (with the laminate backing) approx. 15 hours at least 60 °C
The following post-cure at elevated temperatures will improve the mechanical as well as the chemical properties and is highly recommended (> 60 °C for 15 h). A rate of heating of < 10 K/h is recommended, to prevent warpage and a print-through of the weave pattern.
Maximum heat distortion temperature after post-curing (15 hours at 100 °C): approx. 120 °C
Applications:
- Negative moulds for hand lay-up and vacuum moulding
- Thermoforming moulds
- RTM moulds
