ALWA MOULD COAT

ALWA BARRIER COAT is a laminate resin, which is applied to protect the gelcoat for instance with glass fleece (e.g., ALWA MOULD COAT and ALWA UP GELCOAT).

ALWA UP GELCOAT is an aluminium filled polyester surface resin with a temperature resistance of 110 °C. Pot life is approx. 20 – 30 min. at room temperature, when using 1 – 2 % hardener (art. no. 3150001). The top layer can be polished to high gloss.

Our patented material is highly suitable to produce foam moulds and RTM pressure injection moulds. Advantages: • Large volumes of more than 2500 kg can be cast in less than 45 min. • Good castability • Hardly measurable linear shrinkage • High temperature resistance • Demoulding process after approx. 90 min. (after adding the last backfilling compound) • Chemical adhesion to polyester or vinylester gelcoat • Immediately after the first mould half has cooled down, the second mould half can be prepared • Copper pipes keep the mould surface on a nearly constant temperature • Post-curing is not necessary ALWA MOULD D backfilling compounds are the fastest system on the market. For the surface you can chose between two gelcoats: 1) ALWA MOULD COAT This is a vinylester gelcoat that is especially suitable for high-end surfaces. It can be polished to high-gloss. 2) ALWA EPF 10 This is an epoxy gelcoat that is easy-to-use and is recommended for parts, where high-gloss surfaces are not needed
