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 EPF 10 is a temperature-resistant, steel-filled gelcoat based on epoxy resin. It is used to produce temperature and abrasion resistant surfaces for vacuum, PU foam, thermionic moulds and heating plates, among others.

ALWA EPT 210 is a laminate and backfilling resin. Laminates can be produced with ALWA EPT 210 in order to manufacture glass fibre plastic parts, gauges, templates, moulds and applications with diverse fillers. ALWA EPT 210 is an epoxy resin that has a low viscosity and a light yellow colour. Under exothermic reaction, it cures in connection with the light yellow hardener H 10 at room temperature. The mixture shows a low viscosity and is particularly appropriate for laminating layers of up to 8 mm. For thicker laminates the application of layers must be interrupted several times in order to avoid too high reaction temperatures in the laminate.

ALWA MOULD SLV is a universal two-component fast casting PU resin for mould making. It is used for the production of milling devices, negatives, product holders, foundry moulds, mould plates, copy moulds, core boxes, pattern plates, casting moulds, prototype parts, supporting moulds and synthetic cast. It consists of a beige-brown low viscosity resin component A (polyol mixture) and a red-brown, low viscosity hardener (component B) based on isocyanate (Methylendi(phenylisocyanat)e = MDI). Two types are available with different pot life: *ALWA MOULD SLV 3 ~ 3 min. pot life *ALWA MOULD SLV 9 ~ 9 min. pot life

Aluminium and mineral fillers

The solvent combination contains methyl methacrylate (MMA) and is used for diluting and cleaning.

ALWA repair filler (art. no. 5100001) is used in order to repair casting resin moulds. The filler is mixed with 1 – 3 % hardener powder.

ALWA PU foam consists of component A (art. no. 9700005) and component B (art. no. 9701006) and is used, for instance, to produce displacers. The mixing ratio between component A and component B is 1 : 1.2 and the density is approx. 30 kg/m³.

ALWA plasticine is used to repair master patterns, round off sharp edges, seal casting boxes and build a parting plane.

ALWA acryl sealer is used to seal porous surfaces, such as wood, gypsum and rigid foams (not suitable for polystyrene foam). The primer dries in the air and forms a strong film. Apply a thin layer of ALWA acryl sealer evenly with a brush. If 3 % hardener powder is added, the curing process can be reduced to approx. 30 min.
