3M™ 7952 (467) Double Linered Laminating Adhesive

Technical Help / Filters

3M™ 7952 (467) Double Linered Laminating Adhesive provides a long-term, environmentally stable bond. The smooth adhesive provides a high-quality appearance on thin graphic overlays, and the high cohesive strength to withstand repeated stresses from switch activation. This laminating adhesive withstands high temperature, high humidity, and is chemical-resistant. The adhesive is very resistant to oxidisation and ozone when exposed to air or UV light.

 

Suitable applications for 3M™ 7952 (467) include attachment of graphic overlay to membrane switch or keyboard, attachment of membrane switch to product housing and lamination to polyester for membrane spacers.

 

Solvent resistance is excellent when this product is properly applied to impervious materials. The adhesive resists softening through edge contact with mild acids, alkalis, oil, gasoline, Kerosene, JP-4 fuel, and many other solvents. Not recommended for total immersion.

 

Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact and thus improves bond strength. For optimum adhesion, the bonding surfaces must be clean, dry, and smooth. Some typical surface cleaning solvents are isopropyl alcohol or heptane.
