UP Casting Resin "transparent"

  • 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

Due to the styrene content, Polyester resins can only be filled in tin cans and canisters. Our metal canisters are UN-approved for the transport of dangerous goods and can therefore withstand drops and impacts. In order to avoid damages, we pack the canisters properly and ship them with approved parcel services and forwarding agencies only. In spite of all measures, it may happen that tin packaging shows transport damages such as crushes or dents. As long as handling and resin extraction are not impaired by this, we unfortunately cannot accept complaints.
