Why Use MAYER Primer?
- Molecular Surface Energy Polarization: Raises substrate energy from <30 mN/m to >45 mN/m for complete adhesive wet-out.
- Automotive & Appliance Standards: Certified reliability for bumper brackets, trim moldings, and electronic housings.
- 1 Liter High-Volume Can: Maximum economy for industrial high-throughput assembly lines.
Standard Operating Procedure (SOP)
STEP 01
Surface Degreasing
Wipe plastic parts with IPA to remove mold release agents and contaminants.
STEP 02
Thin Coat Application
Apply a thin layer of MAYER Primer using a lint-free pad or sponge.
STEP 03
Activation Window (30-60s)
Allow 30-60 seconds flash-off time for polymer polarization.
STEP 04
Adhesive Bonding
Apply VHB acrylic foam tape or PU structural mastic.
Frequently Asked Questions
Will acrylic tape bond to PP without primer?
No. Untreated PP and PE have low surface energy causing tape to peel off easily. MAYER Primer creates an active polar layer for permanent bonding.
Is it compatible with EPDM rubber seals?
Yes, it provides outstanding adhesion on EPDM door seals and window weatherstripping.
