At this year's Shanghai International Tape and Film Exhibition (APFE), Wacker Chemie will launch DEHESIVE® PSA 84X series solvent-based silicone pressure-sensitive adhesives. This series includes 3 products with low, medium and high adhesion, which can be matched with each other to achieve the required adhesion range for the application. At the same time, WACKER will also exhibit a silicone release agent specially developed for release paper and release film. Among them, DEHESIVE® SF 500 is a light release product with a solvent-free system and has a wide range of applicability. EM 495 is a water-based release agent, which can be flexibly adjusted according to the release force and coating conditions. APFE 2020 will be held in Shanghai, China from September 28th to 30th.
WACKER`s newly launched DEHESIVE® PSA 84X series of solvent-based silicone pressure-sensitive adhesives includes three products with low, medium, and high adhesion strengths, which can be matched to achieve the desired adhesion range for the application.
In the use of pressure-sensitive adhesives, it is often necessary to mix two products with different adhesion forces to achieve the specific adhesion range required by the application. If you only rely on low-viscosity and high-viscosity products, the adjustment of adhesion is difficult to accurately control and the efficiency is low. WACKER’s newly launched DEHESIVE® PSA 84X series of solvent-based silicone pressure-sensitive adhesives include products with different adhesion ranges from low, medium and high. The same solid content and close viscosity make it easy to mix and make formulation adjustment more convenient and efficient. This series of pressure-sensitive adhesives also have the characteristics of good coating appearance, low temperature curing and long bath life.
During APFE 2020, WACKER will also exhibit silicone release agents specially developed for release paper and film:
DEHESIVE® SF 500 solvent-free system
DEHESIVE® SF 500 is a solvent-free silicone release agent suitable for light release. The product has a fast curing speed, and the release force during low-speed peeling can be as low as 1-3 g/inch. DEHESIVE® SF 500 has excellent adhesion to a variety of substrates, with high residues and less silicon transfer, and is suitable for a variety of adhesive systems and coating methods. Combined with WACKER's light release additive ADDITIVE® R2 and anti-adhesive additive DEHESIVE® SF 500HJ, it can provide a larger adjustment space for the release force range and keep the film surface dry even in the case of high coating volume. stick.
DEHESIVE® EM 495 release agent emulsion
DEHESIVE® EM 495 is an emulsion release agent. The main agent does not contain a crosslinking agent. The formula can be flexibly adjusted according to the release force and coating conditions. DEHESIVE® EM 495 also has excellent shear stability and excellent wettability. In the case of low platinum addition, it still has a faster curing speed and excellent adhesion. The products can be widely used in labels, tapes, wrapping paper, hygiene products and baking paper.
