Adhesive Applications SA1911 – Polysil Silicone/Acrylic Double Coated Adhesive Tape SA1911

SA1911 is a double-coated, double-linered polyester (PET) tape with a silicone adhesive on the PET side and an acrylic adhesive on the Kraft side. SA1911 provides a solution for adhering silicone-based substrates to non-silicone materials. The silicone adhesive is designed for bonding to low surface energy materials, including silicone foam and rubber. The acrylic adhesive offers high adhesion to a wide range of materials and excellent heated shear properties. Engineered for bonding dissimilar materials Excellent conformability Maintains performance at high temperatures Silicone PSA gives a superior bond to silicone materials, including foams and LSR substrates Maximum Service Temperature 350°F (177°C) Minimum Service Temperature -40°F (-40°C) Peel Adhesion (Acrylic) 70 oz/in (19.45 N/25mm) Peel Adhesion (Silicone) 72 oz/in (20.00 N/25mm) Product Thickness (Total) 5.50 mils (0.140 mm) Shear Adhesion >168 hrs @ 2.2 psi (>168 hrs @ 15.2 kPa) Tack (Acrylic) 42 oz (1191 g) Tack (Silicone) 38 oz (1077 g)
