Our Polyester Barrier Coat was developed from a proprietary resin blend with high quality raw materials and special additives.
This coating acts as a barrier coat between the laminate and the gelcoat. This formulation provides superior osmosis resistance along with enhanced thermal and cracking resistance properties.
Sogel’s Polyester Barrier Coats allow accelerating the cure and the demoulding time, while strongly reducing the risk of print through, orange peel and blisters on gelcoat surface.
The advanced technology of Sogel Polyester Barrier Coat provides them with the following properties:
- Low shrinking
- Full cure in thin layers
- Increased impact resistance
- Improved osmosis and blister resistance
- Significant reduction of print through
- Excellent flexibility and crack resistance at demold
- Excellent porosity resistance with minimal pin holes after post-cure
Sogel’s Polyester Barrier Coats have been designed for use in the manufacturing of transportation parts, in the construction industry of swimming pools and water parks and other composite parts using hand lay-up or spray-up application methods.
