Product Description
191 is an orthophthalic based polyester general-purpose resin. It have several different variants:
1, 191(LSE) is an environment friendly variant of 191. Compared with 191, the LSE variant has lower styrene emission which could protect the employees who need to apply it in the closed space.
2, 191P is pre-promoted 191 resin. The color of 191P is pink, while the 191 is yellow.
3, 191TP is thixotropic and pre-promoted 191 resin. It is pink troubled liquid.
Potential applications:
1, Boat Construction
2, Pultrusion and RTM
3, Filament Winding Pipe
4, SMC/BMC
5, Painting
6, Translucent Panel
