| Flexibond MS-939 is a one-component elastic bonding adhesive based on silane-modified polymer. It combines the advantages of both polyurethane and silicone, and thus is a new generation elastic adhesive. It is free of silicone, isocyanate and solvent. It cures quickly to form durable elastomer when in contact with moisture at ambient temperature. ADVANTAGES One component, non sag, easy to apply; Able to partially or completely replace conventional fasteners; High initial tack and fast positioning; Excellent adhesion without activator and primer; Good heat and UV resistance; l Best environmental adhesive; CHARACTERISTICS Color: black, white, grey Odor: no Solid content: 100% Appearance: uniform paste Density: ca. 1.45 g/cm3 Tack free time(DIN 50014): 10min Curing rate(DIN 50014): 3 mm/24hr Sagginess(DIN 52454): 0 Volume change(DIN 52451): <2% Shore A hardness(DIN 53505): 55 Tensile strength(DIN 53504): 3.0 MPa Elongation at break(DIN 53504): 250% Shearing strength(DIN 53283): 2.5 MPa Application temperature(°C): 5~40 Service temperature(°C): -40~100 Application Flexibond MS-939 is used for the bonding of parts in following industries: bus body, railway carriage, container, equipment engineering, air-conditioning and ventilation, metal and sheet metal working, plastics technology, ship building, etc.. ADHESION Flexibond MS-939 has good adhesion on metal (fresh, parkerized, galvanized, painted), stainless steel, copper, aluminium (fresh, anodized, painted), glass, PC, PUR, ABS, polyester, most thermal plastics, EPDM, PS, PA, PVC, etc.. But prior test is absolutely necessary. For some substrates, the use of activator and/or primer will help to achieve optimal adhesion. |
