Surface Preparation: The bonding surface must be relatively clean and dry.
Contaminated surfaces should be cleaned with a 50/50 Isopropyl Alcohol and
water mixture. A clean lint-free cloth should be used.
Shake 3M VHB Tape Universal Primer UV well before using. Apply a thin uniform coating to the bonding surface using the minimum amount that will fully coat the surface. Allow 3M VHB Tape Universal Primer UV to dry thoroughly before applying tape (30-90 seconds). The tape should be applied or the bond made to the prepared surface within 8 hours of primer application. Be sure the primed surface remains free from contaminants prior to applying the tape. Porous surfaces may require 2 applications of primer for uniform coverage and good adhesion. Allow first application of primer to dry before applying the second coat. 3M VHB Tape Universal Primer UV may be applied with a brush, swab or felt-tipped dauber bottle applicator(1), a pressurized flow gun, knurled roller or other similar type of application equipment. Applicator heads should be cleaned or replaced regularly.
3M VHB Tape Universal Primer UV can be removed with acetone. Vigorous scrubbing may be required. Test in small area to ensure acetone will not affect the substrate surface.
