SMG533 Silicone Sealants Used For Solar Panel Luminum, PPO, TPT/TPE Backsheet Black White Gray Or Customized Color
◆ One component, neutral alkoxy curing silicone sealant, fast curing
◆ Easy to use, good aging resistance, water resistance, ozone resistance, UV resistance
◆ It has excellent adhesion to the photovoltaic panel materials, including solar panel aluminum frame, glass, TPT/TPE, etc.
◆ Excellent durability test: Pass the thermal shock test (-40-85℃), damp heat test (85℃/85%RH/1000 h) and other related aging tests. Will not soften or degrade after curing, and always maintain good elasticity
◆ Have complete certification qualifications and passed SGS, UL, TUV certification.
◆ Used for PV modules frame sealing, junction box adhesion and rail bonding
◆ Solar panel aluminum frame and glass,
◆ TPT/TPE Backsheet

Noted:All the above data come from 23±2℃and 50±5%RH curing condations after 7days.
◆The surface of substrate must be clean and dry, preferred solvents including isopropanol, acetone, and methyl ethyl ketone.For some special substrates, such as PP and PTEE, needed chemical corrosion or plasma treatment to meet bonding effect.
◆ Match pneumatic dispenser or machine to meet dispensing process.
◆After skin formation, cure continues inward from the surface. In 24 hours (at 25℃and 50% relative humidity). SMG533-S will cure to a depth of about 3.3 mm. The deep-seated part, especially the part that has limit contact with air has longer curing time. Similarly curing time would extend in low-temperature condition.
