Product advantages
1. The adhesive does not flake during processing and storage, maintaining uniform composition properties of the adhesive and overcoming the drawback of poor adhesion caused by flaking, as well as preventing contamination of rubber products and molds.
2. There is no migration phenomenon between adjacent layers of adhesive, maintaining the surface stickiness of the adhesive.
3. It reduces scorching during mixing and storage.
4. It shortens the curing time and reduces the amount of sulfur used, which is beneficial for improving the aging performance of rubber products.
5. It enhances the adhesion between rubber and other materials.
6. It has the characteristics of high dispersion and high thermal stability.
FAQ
Q: What are the key features of IS7020?
A: The insoluble sulfur content is ≥ 70%, with high sulfurization efficiency and strong steel wire adhesion, making it suitable for high-end rubber products.
Q: Can it replace the previous IS60 series?
A: Yes, it can. Especially in scenarios with high requirements for sulfurization stability and adhesion, the effect is even better.
Q: How long is the storage period?
A: Store in a sealed and dry environment. The shelf life is 12 months. Avoid high temperature and humid conditions.
