The development trend of silicone pressure-sensitive adhesives is moving towards being thinner and being more capable of dealing with difficult-to-bond materials. In the protective film industry, as market competition intensifies day by day, manufacturers are actively seeking effective ways to control costs while pursuing product adhesiveness and reliability. Reducing the thickness (amount) of the adhesive coating has become an important strategy, aiming to optimize material usage and improve production efficiency so as to remain competitive in the fierce market competition. Meanwhile, the application scenarios of pressure-sensitive adhesives are constantly expanding, especially in the application on the surfaces of difficult-to-bond materials. For example, the emergence of anti-fingerprint screens has posed new challenges to the performance of pressure-sensitive adhesives. Anti-fingerprint technology endows glass covers with multiple properties such as hydrophobicity, oleophobicity, scratch resistance, anti-fingerprint and smooth touch by coating a layer of fluorine-containing coating with extremely low surface tension on the surface of glass covers. However, such specially treated surfaces are often more difficult to adhere to, putting forward higher requirements for the adhesiveness, weather resistance and cleanliness after peeling of pressure-sensitive adhesives. Therefore, in order to meet the market demand for thinner and more strongly adhesive silicone pressure-sensitive adhesives, research and development teams are constantly exploring new materials and technologies to improve the comprehensive performance of pressure-sensitive adhesives. This will not only help protective film manufacturers better cope with market challenges but also bring consumers higher-quality and more reliable protective film products.
