Applications & Uses

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.

Application Limitations

When bonding and sealing PMMA and polycarbonate, under tension, stress corrosion cracking may occur. In such cases MS1937 should not be utilized.

Properties

Adhesion Information

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.

Paintability Information

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.
