Smartflex-265 Polyurethane Sealant, For Construction

Smartflex-265 Polyurethane sealant :FEATURES : Primerless adhesion to most building materials Non-sag formulation Excellent weatherability Paintable Cures to a tough, flexible rubber Tools easily. Smartflex-265 is low modulus one-component moisture curing Class A polyurethane sealant. It cures into a flexible, durable and weather resistant elastomeric sealant that has very good adhesion to most construction and industrial materials. It can accommodate cyclic joint movement of 50% (+/-25%) of the joint width. Smartflex-265 is recommended for use in moving expansion joints between precast concrete panels, brick and block work, granite, marble and sandstone, aluminum windows, FRP, metal, coated metal curtain walls and seams on timber, aluminum, U-PVC joinery, etc.Smartflex-265 can be used for bonding or sealing lap seams on trucks, bus, trains, trailers, roofs vans, RV's specialty vehicles and constructions panels.SPECIFICATIONS : Smartflex-265 Polyurethane Adhesive/Sealant meets or exceeds the following: TT-S-00230C (Type II) Class A, ASTM C-920 Type S Grade NS, Class 25, Use- NT, Aand M. ::TYPICAL PROPERTIES:: Chemical base 1-C polyurethane Color WHITE/Black Cure mechanism Moisture Cure Density (uncured) 10.1 lb/gal VOC (EPA method 24) 0.53 lb/gal (64 g/l) Non-sag properties Very Good Application temperature 50°F - 95°F (10°C - 35°C) Tack free time 45 min Open time 30 min Shrinkage <1% Shore A-hardness (ASTM D 2240) 45 Tensile strength (ASTM D 412) 870 psi Elongation at break (ASTM D 412) 450% Tear propagation resistance (ASTM D624) 57 pli Volume Resistivity (ASTM D 257-99) 106 Wcm approx.
