  • Best Practices for 3M Scotch-Weld Gasket Maker GM18

    *See Terms of Use Below

    1. Surface Preparation

      3MTM Scotch-WeldTM Gasket Maker Anaerobic Adhesives are not recommended for use on most plastics due to potential cracking of plastic parts. Also, they are not recommended for use in piping systems that contain pure oxygen or an oxygen-rich environment, chlorine, or strong oxidizing substances.

      Ensure parts are clean, dry and free from oil, grease and dirt. For best results, clean and dry parts with solvent or 3MTM Scotch-WeldTM Activator. (Activator can also be used on inactive surfaces or to accelerate the cure on active surfaces.). NOTE: Use of a 3MTM Scotch-WeldTM Activator may reduce bond strength depending on substrates and gap. Testing is recommended to evaluate the effect.

      If not sure of surface type, always use activator. Refer to Material surface Activity and Cure Speed section for more information.

    2. Application

      Apply a continuous bead of adhesive by had tracing or by automated tracing equipment onto one surface of the flange or mating part. Circle all bolt holes. 3MTM Scotch-WeldTM Gasket Maker Anaerobic Adhesives can also be applied by screen printing, roll coating, pads, etc.

      Assemble parts and tighten as soon as possible. Making sure to apply fastening pressure evenly on all sides of the mated assemblies.

      It can be applied by tube, tracing, roll coating, or screen printing to provide an instant low pressure seal.
