  • Best Practices for WEICON Solar-Flex

    *See Terms of Use Below

    1. Surface Preparation

      The surfaces must be clean and free of grease. Many surface contaminants, e.g. oil, dust and dirt, can be removed with WEICON Surface Cleaner. For heavily soiled metal surfaces, we recommend WEICON Cleaner Spray S

      WEICON Sealant and Adhesive Remover is suitable for removing old paint or adhesive residues. Most materials can be bonded well to themselves and among each other. For certain materials or extreme requirements, we recommend the use of an adhesion agent (primer). Detailed information on this subject is contained in the primer selection table. A mechanical surface pre-treatment, e.g. sanding or sandblasting, can considerably improve the adhesion.

    2. Application

      Professional cartridge gun for 310 ml cartridges, compressed air gun (we recommend<br />a variation with piston rod), automatic dosing systems. Joining the parts to be bonded

      To ensure optimum wetting, the parts must be joined before the first skin has been formed on the adhesive (skin-over time).
