Product Description

TM-191D Unsaturated Polyester Resin

1.Brief Introduction:
TM-191 UPR is a kind of general purpose use UPR, low viscosity, good mechanical strength and high elongation. It can be applied in all kinds of FRP products as well as lay-up products.
TM-191D UPR is a kind of DCPD(dicyclopentadien) UPR with medium viscosity. The resin has excellent wettability to glass fiber. FRP products made of 191D UPR have good air-drying ability, low shrinkage and good water resistance. TM-191D can be applied in all kinds of  FRP  products.

Remark:
1) casting matrix should follow GB/T8237-2005. Curing system: accelerator 0.8%Co/oct 1.0 %, curing agent: Butanox M-50 1.5%.
2) Post-curing of casting matrix: room temperature*24 hours+60ºC*3 hours+110ºC*2 hours.
3) Post-curing of FRP: room temperature*24 hours+60ºC*3 hours+110ºC*2 hours.
 
4,Instruction for use
1) High efficiency colorless accelerator shall be avoided in use. Otherwise, it will be easy to cause poor curing of products, which leads to surface stickiness. Special FRP accelerant such as E4 shall be selected to use.
2) When the ambient temperature is high and the gel time of resin is short, do not reduce the dosage of curing agent, gel retardants should be added as needed.
3) When the humidity of construction environment or the temperature is high, it is also easy to cause the surface to become sticky. Wax liquid can be added appropriately.

5,Storage And Transportation
The loading and transportation must follow the rules in chapter 5 of dangerous chemicals regulations .The products should be stored under 25ºC and avoid the sunlight, heat source ,fire source and radiant point. The shelf life in right environment is 3 months.
