ZQ452 T-type silica gel

ZQ452 T-type is a general-purpose low viscosity room temperature curing one component silicone potting and batch application adhesive. This product has low viscosity and is easy to apply. It can also be sprayed with solvent dilution equipment. It is easy to use and has good adhesion. Except for slight corrosion to copper, most metals have no corrosion. It has excellent cold and heat alternating resistance, aging resistance and electrical insulation, excellent moisture-proof, earthquake resistance, corona resistance and leakage resistance.

Note: All mechanical and electrical properties are measured after curing for 7 days under the conditions of 25℃ and 55% relative humidity. The performance of each type of silica gel is subject to the actual test report.

Use process and precautions

1. Clean the surface: clean the surface of the adhered or coated object to remove rust, dust, oil and other pollutants.

2. Apply    Glue: unscrew (or cut off) the cap of the rubber hose, squeeze or spray the glue onto the cleaned surface to make it evenly distributed.

3. Solid    Plasticization: place the glued parts in the air and let them cure naturally. The curing process is a curing process from the surface to the inside. Within 24 hours (room temperature and 55% relative humidity), the adhesive will be cured to a depth of 2 ~ 4mm. If the sizing position is deep, especially where it is not easy to contact the air, the complete curing time will be extended. If the temperature is low, the curing time will also be extended. It takes more than 7 days for the 6mm thick sealant to be fully cured. It is recommended to use tomorrow's two-component potting adhesive for potting with a thickness of more than 6mm.

4. After the operation, the unused glue shall be immediately tightened and sealed for storage. When used again, if there is a little crust at the seal, it can be removed without affecting the normal use. During the storage of the adhesive, a small amount of curing may occur at the nozzle, which can be used normally after being removed without affecting the product performance. If it accidentally enters the eye before curing, see a doctor.
