CRYSTIC U1155PAECC is a thixotropic, pre-accelerated, orthophtalic unsaturated polyester resin with a low viscosity and a good reactivity. The resin features a low styrene content which is combined with a low styrene emission system. During the spray up phase, styrene emissions from Crystic U1155PAECC are considerably reduced compared to normal spray applied resins. The product contains a colour change system that reacts when the catalyst is added.  

CRYSTIC U1155PAECC should be allowed to attain workshop temperature (18 – 23°C) before use. It needs only the addition of the catalyst to start its curing reaction. The colour change mechanism will drive the resin to change from blue to green then to yellow/brownish colour. The resin is suitable for general purpose applications such as transport, building and industrial parts.  

Features and Benefits Features    

  • Benefits Low styrene content / emission: Better comfort for the workers and for the neighbourhood
  • Colour change: Safety factor to control the addition of catalyst
  • Low viscosity: Rapid wet out of the reinforcement
  • Good reactivity: Fast mould turn round  


The following cold curing formulation is recommended:

CRYSTIC U1155PAECC: 100 parts Catalyst M : 1 to 2 parts

Catalyst M is a Méthyl Ethyl Kétone Peroxyde at 50% such as the Butanox M 50 from AKZO or Luperox K1S from Arkema.
The ambient temperature, the quantity and the type of catalyst will control the gel time of the resin. The gel time at 25°C of 100 g of resin with 2 ml of Catalyst M is 14 – 16 mins. Curing should not be carried out at temperature below 15°C.  


Since certain pigments, fillers or extra styrene may the affect properties of CRYSTIC U1155PAECC their effect should be evaluated before addition to the formulation.


For most applications satisfactory result will be obtained by curing at room temperature (20°C). Some improvement in properties may be obtained by post-curing 16 hours at 40°C after release from the mould.

Heat Distortion Temperature (HDT): 70 ºC
