Description of 3M VHB Universal UV Primer

3M VHB Universal UV Primer is a bonding primer that optimizes the adhesive performance of a bond on many substrates, including difficult to bond surfaces.


It has the same performance as 3M 94 primer but integrates new features such as an innovative fluorescent tracer that makes it visible under UV light. this allows you to effectively check that the primer has been properly distributed on your substrate, using an ultraviolet lamp. This reduces the risk of errors and contributes to good industrial traceability if the surface has been primed in advance or by someone else.


It is ideal for reinforcing bonding with 3M VHB double-sided adhesive tapes.


3M Universal UV Primer is particularly recommended for bonding to metals, painted surfaces and plastics such as polypropylene, ABS, PMMA, polycarbonate, polyamide, reinforced plastics, rigid PVC and other difficult to stick substrates.


Use on polyethylene is not recommended.


Its formulation has been designed to combine performance and safety :

  • UV indicator: effective quality control in industry
  • Fast drying : increased productivity
  • No CMR substances : more respectful of health and environment
