Instructions                                                           

◆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.
