Compound D

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 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 Surfaces of: Polyester gelcoat Vinylester gelcoat Foam moulds Surfaces of: Polyester gelcoat Vinylester gelcoat Epoxy gelcoat Metal spray surface layer (zinc) Galvano For example suitable for: Polyurethane (PU) foam injection Resin injection moulds Reaction injection moulding (RIM) / Structural reaction injection moulding (SRIM) PU reaction injection moulding PU integral foam moulds PU flexible foam moulds Glass fibre mat reinforced thermoplastics (GMT) and fibre reinforced polymer (FRP) for prototypes and small series Cold and hot pressure moulds up to 130 °C Application: - Foam molds, cold press molds, Pouring or ramming mixes, RTM pressure injections Preparation of the backfilling Calculate the complete casting volume in litres (e.g., calibration with water or sand) and multiply the amount with the density = complete quantity of backfilling. Bend the copper pipe over the pattern and fix it to the prefabricated casting box with a distance of 20 – 40 mm from the pattern’s surface. The pipes should have a distance of approx. 60 – 80 mm to each other. Screw the casting box with the fixed copper pipes to the model and then begin to seal.
