Best Practices for 3M 94 Tape Primer
-
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.
Carefully read and follow manufacturer’s precautions and directions for use when handling cleaning solvents.
-
Application
Shake 3M primer 94 well before using. Apply a thin uniform coating to the bonding surface using the minimum amount that will fully coat the surface. Allow 3M primer 94 to dry thoroughly before applying tape. This is usually accomplished in 5 minutes at room temperature. Be sure the primed surface remains free from contaminants prior to applying the tape. Porous surfaces may require 2 applications of 3M primer 94 for uniform coverage and good adhesion. Allow first application of primer to dry before applying the second coat. 3M primer 94 may be applied with brush or swab. It can also be applied with a pressurized flow gun, knurled roller or other similar type of application equipment.
-
Clean-Up
3M Primer 94 can be removed with acetone. Vigorous scrubbing may be required. Test in small area to insure acetone will not affect the substrate surface.
