Preparing the Surface

The user should check the compatibility of the product with the surface in terms of adhesion and chemical compatibility over the application temperature range. The surface should be clean, dry, smooth and dust-free.

Installation Guidelines

Prepare the surface and proceed as follows:

  • Choose the most suitable width and metal finish of the Infra-Flash™;
  • Unroll the tape until the desired length is reached;
  • Remove the silicone release film that covers the adhesive part of the tape and position Infra-Flash™;
