JDB832 silicone sealing silicone

JDB832 is a single component adhesive sealing silicone rubber that solidifies at room temperature with moisture in the air. The curing speed is fast, with low organic volatiles during curing and no odor after complete curing. It has good adhesion to metals and most plastics, and is particularly suitable for the bonding and sealing of difficult to stick materials. The cured material has good toughness and moisture-proof and shockproof functions.

Feedback

Feature

➢ The product has a short surface drying time and fast deep curing, which is conducive to rapid bonding.

➢ Excellent flame retardancy, fully compliant with the EU ROHS directive requirements.

➢ Excellent adhesion performance, with good adhesion to most metals, plastics, ceramics, and glass.

➢ Excellent weather resistance, moisture resistance, and heat resistance; Good electrical insulation performance.

➢ After curing, the adhesive layer is made of elastomer, which releases alcohol substances and has no corrosion on materials such as PC, ABS, and metals.

➢ The mechanical and electrical performance is stable within the range of -50 ℃ to 200 ℃.

application

Usage method

Instructions for use

● Clean and dry the surface of the adhesive object, and remove any pollutants such as rust, dust, and oil that may affect adhesion.

● Extrude the adhesive with a special tool and apply it to the cleaned joint surface.

● Under the condition of 23 ± 2 ℃/50 ± 5% humidity, the surface should dry within 10-20 minutes and cure within 48 hours with a coating thickness of approximately 2-3mm. Low temperature and dry climate conditions require an extension of curing time.
