Product Introduction
TPR (thermoplastic rubber) and TR materials inherently have low surface energy and high chemical stability, which often makes it difficult for adhesives to form effective adhesion. Achieving a strong bond has always been a challenge in production. To address this industry pain point, we have launched TPR shoe primer TR121. This product is specifically designed for precise pretreatment of such hard-to-bond substrates, laying a solid foundation for subsequent bonding processes.
In terms of formulation, TR121 features low odor, improving the workshop environment while maintaining core performance. It exhibits excellent penetration and wetting properties, efficiently activating the substrate surface to provide essential support for long-term, stable bonding.
The key advantage of this primer is its fast activation speed, quickly enhancing the initial tack of the substrate and making it more suitable for subsequent application of high-performance adhesives. More importantly, when used to treat TPR and TR outsoles and various components, it effectively avoids the common industry issue known as "rotten bottom," and does not cause excessive glossiness or an oily appearance on the substrate surface. This preserves the material's inherent properties while maintaining the integrity and aesthetics of the finished product. During application, it is recommended to add 1.0–3% additive B powder to the primer, which effectively adjusts its rheological properties and improves coating uniformity.
TPR shoe primer TR121 is suitable for key processes such as sole bonding, component assembly, and multi-material lamination. Especially when used with PU adhesives or reactive adhesives, it significantly enhances bond strength and eliminates the risk of bond failure at the source. Its application scenarios are extensive, meeting the production needs of various types of footwear including casual shoes, outdoor boots, sandals, and work footwear. For manufacturers, choosing this primer enables precise surface treatment without damaging the substrate, ensures stable bonding performance, extends product durability, and maintains the aesthetic quality of the finished product-comprehensively improving overall product quality.
