hotmelt butyl sealant

SL 100 BUTYL SEALANT FOR IG PRIMARY SEALDescription: SL100 is butyl sealant designed for use as the primary moisture barrier in dual sealed insulating glass units. It exhibits low argon permeability, excellent adhesion to glass and aluminum, good compressibility, and inherent moisture vapor resistance. Applications: It can be used for the manufacture of insulating glass units. Together with our SL333 two-part polysulphide, SL 888 two-part silicone sealant or SL 818 two-part non-structural silicone sealant for insulating glass, they form an excellent dual-seal system. Technical Property: Color: Black Specific Gravity: 1.20±0.05g/cm3 Solid Content: 100% Moisture Vapor Transmission: ≤0.1g/m2/24hr Press Flow Extrusion Viscosity: 25seconds (110°C, 8.6mm orifice) Compression Resistance: 2.3mm (Flow characteristics Under Load) Tensile Strength: 30 psi cohesive faliure (Glass/Aluminum) Hardness, cone penetration: 55 dmm (150gm load) Service Temperature: -40°C 130°C Suggested Application Temperature: 110°C 150°C Packing: different packing size available according to customer’s requirement. Two diameter specification,one is 160mm 5kg/carton ,one is 180mm.7kg/carton. Shelf Life and Storage: Under the temperature of -10°C 35°C, has a shelf life of 24 months. Application Instruction: Clean and dry adhesion surface to get rid of dirty, oily things. JOINSIL 121 is applied by special hot-melt butyl extrusion machine. The extrusion condition could be satisfied through temperature and pressure adjustment, for example, temperature could be adjusted over the range of 100°C 130°C. The enviroment temperature should not be lower than 10°C in application.
