Can be used to promote adhesion of 3M tapes to surfaces such polyethylene,
polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal and painted metal surfaces.Application Techniques 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.
Apply a thin uniform coating to the bonding surface using
the minimum amount that will fully coat the surface.
Allow adhension promotor 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 adhension promoter. for uniform coverage and good adhesion.
Allow first application of primer to dry before applying the second coat.
It can also be applied with a pressurized flow gun, knurled roller or other similar type of application equipment.
