When bonding high-end polymer materials, conventional surface treatment just isn't enough-if you want a strong bond, you need to prepare the substrate from the ground up. Shoemaking promoter 212F is a surface treatment agent developed specifically for hard-to-bond polymer substrates, especially suitable for various polyurethane and thermoplastic polyurethane materials. Its core function is to clean and activate the substrate surface, increase surface energy, and turn those low-surface-energy plastics that don't bond well into qualified substrates that can hold high-strength adhesives firmly-laying a solid foundation for subsequent bonding.

If you want this primer to deliver its best performance, here's a key tip: before use, add about 5% of hardener F306 or F309. This triggers a crosslinking reaction, making the primer film tougher and more resistant to chemicals. This reinforced treatment layer works especially well on polyether-based PU and engineering elastomers-materials where ordinary primers often fail to achieve ideal bonding results.

In terms of actual mechanism, shoemaking promoter 212F follows a multi-step approach commonly used in industrial bonding: thoroughly remove contaminants from the substrate surface, then apply mild etching, and finally form a chemically active layer. This sequence significantly improves adhesive wettability and mechanical interlocking, resulting in much more reliable bonds. Whether its sole attachment, composite lamination, or multi-material assembly in shoemaking-any process that demands high bonding reliability-using this primer effectively reduces the risk of delamination. This has been proven across industries like footwear, automotive, and technical goods.

The primer formulation of shoemaking promoter 212F is particularly flexible-easy to use yet reliable enough for industrial production environments. Incorporating it into your standard processes significantly improves bond strength and long-term durability between polymer substrates, as well as between polymers and dissimilar materials. It's especially suitable for producing high-end products and precision components that need to maintain stable performance under demanding conditions-helping you protect product quality and enhance environmental adaptability.

1. After cleaning the shoe material surface, evenly apply this primer using a brush or cloth.
2. Drying time: Dry in an oven at 55±5°C for 2–4 minutes before applying the adhesive.
3. Apply the adhesive evenly and completely, avoiding insufficient coverage or excessive buildup.
