Surface Treatment Agent | 3M Tapes Primer
  • Surface Treatment Agent | 3M Tapes Primer

    (Re-upgraded Version, Added: Alternative to 3M Primer 94)



    Are you troubled by poor adhesion when bonding adhesive tapes on PP, ABS, PVC, Nylon, Acrylic, plastics and metals?


    Have you ever experienced your double-sided tapes lifting, peeling or falling off unexpectedly after application? You spend hours reworking failed parts, discard defective finished products, risk delayed shipments and even lose valuable customers. Many factories rely on imported 3M Primer 94 for tape bonding, yet it comes with high cost, long lead time and tight supply constraints. All these costly troubles happen because many plastic and metal substrates are low surface energy materials. Ordinary tapes cannot grab tightly onto these smooth surfaces, leaving you with unstable bonding results that eat into your profit, slow down your whole production line and damage your brand reputation.


    If you are fed up with unreliable tape adhesion and endless rework, and looking for a cost-effective substitute for 3M Primer 94, we have the perfect solution for you.


    Our 3M tapes primer is a professional surface treatment agent engineered specifically to solve tough tape bonding problems. It is a high-performance alternative to 3M Primer 94, delivering matching adhesion boosting effect for double-sided tapes and VHB tapes. It modifies the surface property of hard-to-stick substrates, builds a high-affinity bonding layer, and lets adhesive tapes lock firmly onto the surface. Whether you are working for electronic assembly, automotive decoration, hardware processing or plastic product manufacturing, this primer will bring you stable, long-lasting bonding performance you can trust.

    How to Use ?

    1. Surface Cleaning: Wipe the silicone rubber or substrate surface thoroughly with lint-free cloth and alcohol to remove dust, oil stains and residual glue. Make sure the surface is completely clean and dry before next step.
    2. Apply Primer: Dip a small amount of this primer with a cotton swab or brush, spread a thin and even layer on the silicone rubber surface that needs bonding. Do not over-apply.
    3. Air Dry: Let the coated surface air dry naturally at room temperature.
    4. Bond & Press: After full drying, attach your double-sided adhesive tape to the treated surface. Press firmly for proper contact to achieve strong bonding.
