Mould Resin P + Hardener P-25 (20 min)


Rate item


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 two-component epoxy resin is coloured black for gel coats in-mould construction with high edge strength and good polishing properties. Mould resin P is processed and cured at room temperature in conjunction with epoxy resin laminates and laminating ceramics. In contrast to resin and metal systems, the surfaces are polishable. This tooling gel coat is hard-elastic, i.e. not brittle, and exhibits good edge strength.

Consumption: approx. 0.6 kg/m² (thickness Ø 0.5 mm)

Hardener P-25

Hardener for Mould Resin P with a pot life of 20 minutes.

  • Excellent chemical resistance (as far as possible styrene-resistant)
  • Free of nonylphenol and benzyl alcohol

Mixing ratio: 100 : 25 parts by weight of resin to hardener
Processing time (100 g preparation at 20 °C): 20 minutes
Gel time (at 20 °C/1 mm layer thickness): approx. 2 hours
Curing time (at 23 °C): 24 hours

Temperature resistance: 70 °C

Processing instructions in GFK mould construction

Error-free application is possible on most release agents. If "eyes" should nevertheless form due to poor wetting of the substrate, a second layer of mould resin can be applied to the still sticky layer after gelation (several hours curing at room temperature). If two coats are applied, any imperfections are removed.

1. apply mould resin with brush, layer thickness approx. 0.5 mm, allow to gel (approx. 2 h at room temperature)
2. if defects ("eyes") are formed due to the release agent, apply a second layer of mould resin, allow to gel
3. apply resin-rich coupling layer of laminating resin, glass fiber shavings + cotton flocks several mm thick
4. place glass fabric in the wet coupling layer and laminate on further layers of glass for reinforcement

Carry out all work wet-in-wet so that the layers adhere well to each other.

Other structures are of course possible. Depending on the size and geometry of the mould, other build-ups are possible:

- Laminate directly onto the mold resin, but starting with very fine fabric so that the structure does not push through.
- Laminate made of carbon fibre fabric, low mould weight, high rigidity.
- Laminate made of carbon fiber fabric and aramid honeycomb as intermediate layer, very low mould weight with high stiffness.
- Laminate made of laminating ceramics; fast assembly, very stiff, but also higher mould weight.
- Massive, stiff moulds made of mould resin with a thick-walled backing of resin and fillers such as sand, Poraver and similar.
