Dekalin Dekasyl MS-2 -monikäyttöliima ja -tiiviste, valkoinen, 290 ml

Dekasyl MS-2 from Dekalin (MPN 6251612) is a multifunctional adhesive and sealant, a good compromise between an adhesive and a sealant for demanding work. The elastic adhesive and sealant is suitable for making elastic joints between components where high bond strength is also required. Application on glass, side sill and wheel trims requires no prior surface treatment. It can be painted over once a skin has formed.

• UV and ageing resistant
• Neutral, odourless and fast curing
• Paintable after skin formation

Applications

• Elastic joints and seals in caravan and motorhome construction
• Bonding roofs of buses, caravans and motorhomes
• Bonding edge profiles of trailers with aluminium or polyester
• Bonding polyester parts to metal frames
• Bonding floor systems
• Sealing weld seams

Properties

• Free of solvents, isocyanate and PVC
• Very good UV and ageing resistance
• Generally good adhesion without primer on various substrates, e.g. Dekasyl MS-2 can be used as a sealant for PVC floor coverings
• Permanently elastic in the temperature range -40 °C to +120 °C
• Paintable after skin formation (wet on wet); this generally does not affect curing
• Compatible with most industrial brush or spray paint systems, both alkyd resin and dispersion paints

Adhesion

In general, Dekasyl MS-2 adheres well without primer to clean, dry, dust- and grease-free substrates of aluminium, stainless steel, galvanised steel, zinc, copper, brass, powder-coated metal, most painted metal surfaces, glass, PVC, polyester (GRP), painted and varnished wood etc. No adhesion without pretreatment on polyethylene, polypropylene and Teflon®. Where high adhesion is required under large thermal or physical loads, especially in humid environments, the use of an adhesion promoter is recommended. For properties on substrates not listed and further information, please contact Dekalin.

Processing

Dekasyl MS-2 can easily be applied with a hand or compressed-air gun at temperatures from +5 °C to +35 °C. For sealing, Dekasyl MS-2 should be tooled or smoothed within 10 minutes (at 20 °C / 50% RH) with a spatula or putty knife previously dipped in a mild soap solution. Avoid soap solution getting between the joint faces and the sealant, as this leads to loss of adhesion. For bonding, the substrates must be joined within 15 minutes (at 20 °C / 50% RH) after applying Dekasyl MS-2. The higher the temperature, the shorter the working time. Generally an adhesive layer of 2 mm is recommended when bonding similar materials (with similar strength). The greater the difference in thermal expansion, the thicker the adhesive layer should be. Further information on this is available from Dekalin. At 20 °C and 50% relative humidity, Dekasyl MS-2 can be painted over with most industrial paints after only 10 minutes. The best possible adhesion of paint layers is achieved when the paint is applied 4 hours after applying Dekasyl MS-2. Clean tools or remove uncured residues of Dekasyl MS-2 with a clean, colourless cloth soaked in acetone or MEK (it is recommended to check beforehand whether the surface is attacked by these cleaners).
