Repair tape YS-XB258
Product Features
YS-XB258 is a adhesive tape for back sheet cracking repair developed by our company. It adopts the coating + composite process. This back sheet has a four-layer structure. The outer layer (air surface) is coated with a self-developed fluorocarbon coating with high weather resistance and anti-yellowing properties. The middle layer is PET polyester film. PET polyester film has good insulation performance. The inner layer (EVA surface) is coated with a self-developed fluorocarbon coating that has excellent bonding performance. The inner layer surface is coated with a pressure-sensitive adhesive that has good bonding and sealing properties as well as good thermal stability.
