SMG533 Silicone Sealants Used For PV Modules Frame Sealing with Excellent resistance to durability test
◆ One component, neutral alkoxy-cure silicone sealant.
◆ Excellent adhesion to typical PV substrates, including anodized aluminum, PPO, glass, TPT/TPE series backsheet, etc.
◆ Excellent resistance to durability test: Passed thermal shock test(-40-85℃), damp-heat test(85℃/85%RH/1000 h), and so on related aging test.
◆ Certified by SGS, UL, and TUV.
◆ Used for PV modules frame sealing, junction box adhesion and rail bonding

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.
