Mould Resin P-N

• New, optimized formulation without reactive diluent*
• Hard elastic, good edge strength
• Excellent grinding and polishing properties (Shore D-Hardness Ø 75)
• 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 (applied thickness 0.5–1 mm) in-mould construction. Mould resin P-N is processed and cured at room temperature. It can be used as a top layer in conjunction with epoxy resin laminates. In contrast to resin and metal systems, the surfaces are polishable.

Consumption: approx. 0.5–1 kg/m² (thickness Ø 0.5 mm)

Processing:

Hardener P-25:
20 minutes of processing time yielding surfaces resistant to styrene (in combination with film release agent PVA).

Please order the hardener P-25 separately

*Technical Notice:
The Mould Resin P-N is based on an optimized formulation that completely eliminates potentially harmful reactive diluents. This not only enhances handling safety for the user but also improves the mechanical properties of the resin, particularly hardness and heat resistance.
 
Reactive diluents are typically used to reduce the viscosity of epoxy resins. However, they also dilute the concentration of reactive epoxy groups, leading to a lower crosslink density in the cured material. This reduction in crosslinking can decrease the hardness of the resin, making the material less rigid and less resistant to mechanical stress.
 
Furthermore, crosslink density significantly influences heat resistance, especially the glass transition temperature (Tg​). Reactive diluents can lower the Tg​ by making the polymer network less rigid. By eliminating these diluents, Mould Resin P-N  achieves improved material hardness and higher thermal stability, making it particularly suitable for demanding applications.
