SKF323 Features
◆ One component, neutral alkoxy-cure silicone sealant.
◆ Excellent adhesion to a variety of substrates, including anodized
aluminum, glass, ABS, PBT, PET, PVC, PC, 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.
◆ Excellent high and low temperature resistance, keeping stable
performance within the range -50 ℃ ~ +180 ℃
Typical Applications
◆ Bonding and sealing of lamp products such as T8 tube,
energy-saving lamp and automobile lamp;
◆ Structural bonding and sealing of various glass, aluminum and
engineering plastics;
◆ Other industries need to bond or seal a variety of USES.

Instructions
◆The surface of substrate must be clean and dry, preferred solvents
including isopropanol, , 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.
Packaging & Storage
Plastic drum packing 300 ml or 2600ml ;
Shelf life is 6 month under dry and cool place under 27℃.
Attention
- Far away from children by storage.
- In case of contact with shin, wash with water.
- If accident contact with eyes, flush with plenty of water
immediately.
- Proposed use in a well-ventilated place.
