- Low-viscosity, light-stabilised orthophthalic acid polyester resin of medium reactivity
- Preaccelerated with cobalt, unsusceptible to cracking
- Transparent after curing
For casts up to one litre in volume, the added hardener (MEKP) should be 1 % (gelling time 35 minutes); for larger volumes, 0,6 % (gelling time 23 minutes). The parts can be demoulded once the reaction heat has disappeared (60-90 minutes). Layers should be cast to a thickness of 2-3 cm (otherwise the reaction heat is too high), the next layer should be cast when the previous layer has started to gel.
The typical shrinkage polyesters undergo when curing means that the cast in most cases detaches from the walls of the mould. This can lead to a slight inadequacy in the curing of the surface, which is then tacky for a time. In the case of larger casts, curing on the air side yields a practically tack-free surface owing to the higher reaction heat and the faster progress of curing.
Processing time: with 2 % MEKP approx. 20 minutes
Store containers cool and tightly closed, durability about 6 months.
Please order MEKP hardener separately
