  • Best Practices for 3M Industrial Adhesive 1870

    *See Terms of Use Below

    1. Surface Preparation

      Surfaces must be clean, dry and dust free. Wiping with a solvent such as methyl ethyl ketone (MEK)* will aid in removing oil and dirt.

      *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.

    2. Application

      For best results, temperature of adhesive and surfaces being bonded should be at least 65°F (18°C). Stir well before using. Porous Surface: Brush, spray or flow a uniform coat on the least porous surface to be bonded. Bond immediately, applying pressure to ensure contact. Non-Porous Surface (or for higher immediate strength): Apply a uniform light coat on each surface. Allow the adhesive to dry until it is tacky but does not transfer to the knuckle upon touching. Then apply sufficient pressure to ensure intimate contact.

    3. Curing

      Drying time depends on temperature, humidity, air movement and porosity of the materials bonded.

    4. Clean-Up

      Excess adhesive may be removed with solvent such as 3M™ Scotch-Weld™ Solvent No. 2 or 3M™ Citrus Base Cleaner.*

      *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.
