Maximum liability. Minimal Compromises. TRAMACO Sets New Standards for Coatings on TPO and PP

Tornesch, March 2026
Challenging surfaces call for smart solutions. With the chlorine-free TRAPYLEN® 9351 W 30, TRAMACO is introducing a high-performance, water-based adhesion promoter to the market that was specifically developed for the reliable coating of TPO and PP surfaces —an application area where many systems reach their limits.

The key lies in the chemically modified polypropylene structure, which enables exceptionally strong adhesion to polyolefin substrates. At the same time, TRAPYLEN® 9351 W 30 offers impressive heat resistance and process reliability—making it ideal for demanding industrial applications in the automotive, packaging, film finishing, and technical coatings industries.

Thanks to its water-based formulation, the product supports modern, more sustainable coating concepts without compromising performance or efficiency. As a raw material for primer formulations, TRAPYLEN® 9351 W 30 offers maximum flexibility: Whether applied by spraying, printing, dipping, or brushing, the adhesion promoter can be easily integrated into existing production processes.

A particular advantage is its ease of use: As a plastic primer, TRAPYLEN® 9351 W 30 can be diluted to a solids content of approximately 10% and, if necessary, supplemented with common additives such as wetting agents, coalescing agents, or rheology modifiers. Even short drying times of 60 seconds at 80 °C enable efficient industrial processes.

With a recommended application weight of just 0.5 to 1.5 g/m² on compact films, the product contributes to material-efficient and cost-effective coating solutions. It is supplied in 120-kg PE drums, and has a shelf life of at least twelve months when stored properly. As a product not classified as hazardous, TRAPYLEN® 9351 W 30 also allows for significantly simpler and more cost-effective transportation.

TRAPYLEN® 9351 W 30 stands for:

  • Reliable adhesion to difficult-to-bond polyolefins
  • Halogen-free
  • High process stability and heat resistance
  • Water-based, sustainable technology
  • Efficient processing and low material consumption

With this product, TRAMACO once again underscores its commitment to combining technical excellence with practical solutions —for coatings that deliver on their promises.
