  • Best Practices for Bostik 7435 Maximum Gap Filler

    *See Terms of Use Below

    1. Surface Preparation

      Parts to be bonded with cyanoacrylates must be clean and free of oil, silicone and mold release agents.

    2. Application

      Do not over apply adhesive, especially high viscosity types. This could increase bond line gap and cause “squeeze out” of adhesive which creates handling and odor problems.

      Best results are obtained on very close fitting surfaces, the thinner the gap between parts the better the bond strength.

    3. Curing

      In low humidity conditions, the use of Cyanoacrylate Accelerator is recommended for rapid fixturing of parts.

    4. Testing

      Because cyanoacrylate may damage some plastics, testing on scrap material is suggested.
