APFE 2020: WACKER Presents New Silicone Pressure Adhesive Series
Shanghai, Sep 28, 2020
At this year’s Shanghai International Adhesive Tape, Protective Film & Optical Film Expo (APFE), WACKER will present DEHESIVE® PSA 84X, which consists of three solvent-based silicone pressure sensitive adhesives (PSA). Featuring low, medium and high adhesion forces respectively, the new PSA series can realize the desired adhesion range by cold blending. Other WACKER product highlights during the show include two silicone release agents developed for paper and film release liners. Among them, DEHESIVE® SF 500 is a solvent-free product with a low release force and wide application range, while DEHESIVE® EM 495 is a water-born release agent which allows flexible adjustment of the formulation according to target release forces and to coating conditions. APFE 2020 takes place in Shanghai, China, from September 28 to 30.
During the application of PSA, it is very common to mix two products with different adhesion forces to reach the desired range. Mixing low- and high-adhesion products makes it difficult to precisely control the adhesion force and efficiently adjust the formulation. WACKER’s new DEHESIVE® PSA 84X solvent-based PSA series contains three products featuring low, medium and high adhesion forces respectively. Due to the fact that they have the same solid content and approximate viscosities, it is easy to mix these products and to efficiently adjust the formulation. DEHESIVE® PSA 84X shows good coating effects, has a long pot life and comes with an excellent curing performance even at lower temperature.
During APFE 2020, WACKER will also present silicone release agents developed for paper and film release liners:
DEHESIVE® SF 500 solvent-free system
DEHESIVE® SF 500 is a solvent-free silicone release agent which offers with a low release force of 1-3 g/inch at low peel speed. The product is fast curing and provides excellent anchorage to a wide variety of substrates with high subsequent adhesion and low migration properties. For a further reduction of release forces, WACKER recommends using the easy release additive ADDITIVE® R2. The anti-stick additive DEHESIVE® SF 500HJ makes it possible to achieve a dry surface even at high coat weight.
DEHESIVE® EM 495 silicone emulsion system
DEHESIVE® EM 495 is an emulsion release agent which does not contain crosslinkers and therefore allows flexible adjustment of the formulation according to target release forces and coating conditions. The product features good stability and excellent wetting properties. It cures rapidly even with a low platinum dosage, and has an outstanding anchorage to substrates. The application of DEHESIVE® EM 495 includes but is not limited to labels, tapes, non-stick packaging, hygiene products and baking paper.
