- Product Highlights
- MS1937 is a good compromise between an adhesive and a sealant based on MS-Polymer. MS1937 is suitable for elastic seal which also high strength is required.
- MS1937 is odorless and free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion without primer to many substrates and is compatible with suitable paint systems. The adhesive/sealant also demonstrates good UV resistance and therefore can be used for interior and exterior applications.

- Application Instructions
- The substrates must be clean, dry, free of oil and grease.
- Sausage is applied with the corresponding Hand or Air pressure pistols. In the case of compressed air application, a pressure of (0.2 - 0.4) MPa is required.
- After application, MS1937 can be smoothed with soapy water.
- Adhesion
MS1937 has been tested and found to have excellent adhesion to the following unprimed substrates: aluminum, acrylic-coated aluminum, brass, steel, stainless steel, glass, fiberglass, ABS, rigid PVC, polyester etc. By the manufacturing of plastics, external release agents are used; these agents have to be removed prior to use. Depending on the surface it can be necessary to roughen the surface or to use a primer as an adhesion promoter to provide optimum adhesion.
- Application Limitations
When bonding and sealing PMMA and polycarbonate, under tension, stress corrosion cracking may occur. In such cases MS1937 should not be utilized.
- Paintability
MS1937 may be over-painted, however due to the large number of paints and varnishes we strongly recommend a compatibility test before application. The drying time of alkyd resin based paints may increase.
