NuFlex 302 cures to form a tough, rubbery solid upon exposure to moisture in the air. Because it does not flow due to its own weight, the sealant can be applied overhead or on side wall joints and surfaces without sagging, slumping or running off.NuFlex 302 General Purpose Silicone Sealant is a medium modulus one-component acetoxy cure, non-sag caulking material. NuFlex 302 General Purpose Silicone Sealant cures to form a sturdy, rubbery solid upon exposure to moisture in the air. Due to its non-sag properties, the sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping, or running off. It adheres to most non-porous construction substrates.NuFlex 302 has excellent resistance to weathering, vibration, moisture, ozone, and extreme temperatures. It may be applied in sub-zero temperatures without loss of extrusion or physical property characteristics and is effective to -46°C (-50°F).Features: Acetoxy cure 100% silicone NuFlex 302 has achieved GREENGUARD GOLD Certification Certified by NSF Water-resistant before, during, and after cure RTV (Room Temperature Vulcanization) Adheres to many substrates Wide temperature range performance 50-year durability Can be applied in sub-zero temperatures Bonds to: Metal Laminates Glass Wood Silicone resin Vulcanized silicone rubber Ceramic Natural and synthetic fibres Painted surfaces Most plastics Basic uses include caulking and sealing around: Form-in place gaskets where there is no oil contact Duct joints Areas that need weather stripping Sinks, basins, showers, and tubs Other uses include: General repairs on a variety of substrates Non-load-bearing bonding Non-stick coating for concrete moulds and forms Specifications: Specific Gravity: 1.01 g/mL Extrusion Rate (3.2 mm orifice, 90 psi): 400 g/min Flow Rate: Nil, non- sag Tack free time (min) (25°C, 50% RH): 10-20 ASTM C 611 - Durometer Hardness, Shore A: 25 ASTM D 412 Die C - Tensile Strength, MPa (psi): 2.25 (325) ASTM D 412 Die C - Elongation: 550% ASTM D 746 - Brittle Point: -62 °C ASTM S 2137 A - Volume Coefficient of Thermal Expansion: 0 to 100°C 9.3 x 104 Thermal Conductivity, Cal/(s)(°C)(cm): 4.5 x 104 ASTM D 257 - Volume Resistivity, OHM-cm: 1.5x1015 ASTM D 149 - Dielectric Strength: 21.7 kV/mm (550 V/mil) ASTM D 150 - Dielectric Constant at 60 Hz, 100 Hz, and 100 kHz: 2.8 ASTM D 150 - Dissipation Factor at 60 Hz, 100 Hz, and 100 kHz: 0.0015 ASTM C 603 - Application Temperature: -29 - 50 °C ASTM C 1299 - Service Temperature: -51 - 230 °C * All Pictures Shown Are For Illustration Purpose Only.
