Technical Details & Test Data

General Instructions
  • Substrate Evaluation: Acrylic adhesive is suitable for bonding a variety of substrates, including many plastic composites, sealed wood, and metals. Low surface energy materials such as polyethylene, polypropylene, silicones and PTFE can be difficult to bond to. Thorough evaluation is recommended when bonding to any questionable surface. An adhesion promoter (primer) for use with pressure sensitive acrylic adhesives may be necessary to facilitate proper bonding, and is available from H.B. Fuller.
  • Preparation of Substrate: The substrate to be bonded should be cleaned with an appropriate solvent, preferably isopropanol (IPA). The acrylic adhesive backed part should be applied within 15 minutes of cleaning. To ensure removal of all contaminants without leaving any residue, use a clean, lint-free wiping cloth or disposable wipe. Never use recycled rags. Other solvents such as hexane, heptane, or methanol may be suitable for cleaning various substrates after thorough evaluation. The substrate must be completely dry through evaporation of the solvent with radiant heat, hot air dryers, or with time before bonding acrylic adhesive backed parts.
  • Adhesive Promoter Application-If necessary: Apply the AP-1 Adhesion Promoter to the substrate(s) either with a lint-free applicator or foam brush. Apply the Adhesion Promoter in a “wet” laydown thickness range of 1-8 mils. Allow the Adhesion Promoter to dry approximately 5 minutes. Don’t touch the Adhesion Promoter.
  • Application of Adhesive Backed Part to the Substrate: Remove the protective release liner from the acrylic tape immediately prior to applying the part to be bonded, being careful not to contaminate the acrylic adhesive. Apply within 15 minutes after surface preparation. Apply the part to be bonded without entrapping air between the tape and the substrate with a recommended minimum application pressure of 15 pounds per inch of tape width to achieve adhesive to substrate contact and maximum bond
