4065 Two-Part Fast Curing PV Module RTV Silicone Sealant For Solar Module Aluminum Frame Junction Box Sealing

4065 (2:1)is a two-component, thixotropic paste, white, fat-shedding room temperature vulcanized silicone rubber. Room temperature neutral curing, fast deep curing, can clean the surface of the module after about 1~2 hours. Good sealing, good adhesion to aluminum, glass, backsheet, and junction box. The colloid is resistant to yellowing, after 85C, 85%RH aging test for 1000 hours, the surface of the colloid shows no obvious yellowing. It has excellent mechanical properties in general and after aging, and has good compatibility with all kinds of EVA. The unique design of the rheological system ensures a good construction process and deformation resistance of the colloid.Product Features1) Fast curing, no glue spillageOnly 40min initial setting timeimproving the efficiency of production lines2)Easy to control ratio, good resistance to fluctuating ratios3) De-oxime type long-term stability and reliability higher cost performanceApplicationsSuitable for PV module frame sealing and junction box bonding, especially for steel frame and large-size modulesProperties before curingPart A                                         Typical Value                   RangeAppearance                             White, half flowingViscosity, mPa·s                             250,000                150,000~350.000(GB/T10247-2008)Relative density, g/cm31.47                        1.40~1.55(GB/T13477.2-2002)Part BAppearance                                   White pasteViscosity, mPa·s                              300,000                 200,000~400,000(GB/T10247-2008)Relative density,g/cm31.46                            1.40~1.55(GB/T13477.2-2002)Mixing characteristicsAppearance                                    White pasteMixing weight ratio                        A: B=1.75~2.05:1Mixing volume ratio                       A: B=1.75~2.05:1Tack-free time, min (25°C)                    10                              5~15(GB/T13477.5-2002)Initial curing time, h (25°C)                   0.5                                ≤2Properties after curingAl shear strength, MPa                          2.0                             ≥1.3(GB/T7124-2008)Tensile strength, MPa                            2.6                            ≥2.0(GB/T528-2009)Elongation at break, %                          500                            ≥250(GB/T528-2009)Hardness, shore A                                  48                              ≥40(GB/T531.1-2008)Volume resistivity, Ω.cm                    1.0×1015≥1.0×1014(GB/T 1692-2008)Dielectric strength, KV/mm                     22                               ≥18(GB/T 1695-2005)Working temperature, ℃                                                        -60~200Directions for useClean-up: Clean the surface, remove rust, dust, oil, etc., and conduct professional surface treatment if necessaryGluing: Open the barrel cover, confirm that the surface of the glue is free of crusts, and immediately install it on the dispensing equipment. According to the operating procedures of the dispensing equipment, apply a glue of a certain diameter to the surface to form a continuous line, and complete the work within the operation time without shifting.Curing: Place the glued components in a ventilated environment to make the glue cure overallStorage: Unused part A can be used next time after being placed without affecting its performance. Part B shall be used once or stored away from air/moisture.CautionsKeep away from children for storage.If the skin is accidentally exposed to the product, wipe with a cloth and wash with water before it cures;If the eyes are accidentally exposed to the product, rinse immediately with water, and seek medical attention in severe cases;It is recommended to use the product in a well-ventilated place;Please consult the MSDS of the product for safety informationPackaging25kg/Bucket          2pcs/Carton;275kg/Drum          2pcs/Tray.StorageStore at 8-28°C in a cool and dry place.Shelf life is 6 months.
