TCR glass is a boron-free and fluoridefree glass fiber. It provides higher mechanical properties (modulus of elasticity) than E glass, superior chemical corrosion resistance, especially very similar acid resistance with traditional ECR glass. Without any content of B2O3and F2, TCR glass is environmentalfriendly throughout all its production process. G1-A-TCR are TCR rovings designed for use in spray-up operations using standard or filled resin systems. This includes applications in tub/showers, FRP building materials, heavy trucks and utility boxes. Its excellent glass lay down makes it especially suitable for vertical surface spray-up. Roving doffs are squareedged, cylindrical packages which are firmly and evenly wound and have a constant traverse length. The packages are designed to provide a smooth run out, and their geometry is controlled to maintain the desired run out performance.

All G1-A-TCR gun roving are manufactured to meet ISO 9001 standards. Besides, these products have obtained the quality certification of Norway Boat code.

G1-A-TCR gun roving are produced from a collection of continuous glass filaments gathered, without mechanical twisting, into a single bundle. The filaments, which make up the bundles, are bonded together with a special size. Multiple bundles are then pulled together to form a strand. The strand is wound into a tubeless package that is ready for use in customer applications.

Unless otherwise specified, it is recommended to store glass fiber products in a cool, dry area. Temperature should not exceed 35°C (95°F) and the relative humidity should be kept below 75%. Glass roving products must remain in packaging material until just prior to their use. If these conditions are respected, the glass fiber product should not undergo significant changes when stored for extended periods of time.


To ensure safety and avoid damage to the product, skids should not be stacked more than two high.
