PU surface primer 792B is a premium surface treatment product developed primarily for polymer materials such as PU, TPU, and various specialty PU sole compounds. It delivers consistent surface activation and uniform treatment results. With a well-established formulation and reliable performance, it offers excellent workability even on production lines with strict quality control requirements.

The most outstanding advantage of 792B is that it breaks away from the traditional primer process requiring oven drying. After application, it does not need forced drying-it cures naturally at room temperature. Its formula also features excellent resistance to blushing; even when applied in humid environments, the treated surface will not turn white or fog up. This makes it especially practical for production during rainy seasons or in high-humidity regions like southern China. By eliminating the drying step, it not only saves energy but also avoids heat-related damage to heat-sensitive components or pre-assembled parts, effectively improving overall production efficiency.

This primer is ready to use straight from the container. It integrates three functions-cleaning, etching, and activation-into one product, quickly preparing the substrate surface for optimal adhesive application. When used with high-performance adhesives, it significantly improves wettability and final bond strength. It offers good compatibility with commonly used PU and TPU materials on the market, allowing a single product to cover multiple substrates and reducing the hassle of frequent changeovers on the production line.

PU surface primer 792B is especially suitable for applications such as high-end footwear materials, functional textiles, and precision polymer component assembly. It is particularly well-suited for heat-sensitive materials or production scenarios where high efficiency is a priority. By incorporating this primer into their processes, manufacturers can achieve strong, durable bonds while simplifying workflows, controlling costs, and ensuring consistent product quality. It is an ideal choice for producing athletic shoes, functional apparel, and engineered polymer products that demand high consistency.

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.
