Heley®TPR Primer

TPR primer is a specialized solution designed to improve the adhesion of adhesives to thermoplastic rubber (TPR) surfaces. TPR is commonly used in footwear, toys, automotive parts, and other consumer products due to its flexibility, durability, and rubber-like properties. However, bonding to TPR can be challenging because of its low surface energy. TPR primer chemically modifies the surface, creating better adhesion sites and ensuring a stronger, more durable bond when using adhesives like polyurethane, cyanoacrylate, or epoxy.

Choose adhesives based on compatibility with shoe materials, such as leather, fabric, or rubber, considering factors like flexibility and durability. You can also contact our team for more details.

Solvent-based adhesives provide strong bonds and fast drying times, while water-based adhesives are more environmentally friendly and easier to clean.

Adhesive performance can be affected by climate; extreme temperatures or humidity may impact drying times and bond strength.

Safety precautions include working in a well-ventilated area, wearing gloves and masks, and following the manufacturer’s guidelines.

The shelf life of footwear adhesives typically ranges from 6 months to 2 years, depending on storage conditions and formulation.
