RTV silicone rubber (room temperature vulcanized silicone rubber)

Introduction:

RTV silicone rubber (room temperature vulcanized silicone rubber) is a milky white viscous liquid, which is prepared by compounding silicone rubber, cross-linking agent, filler and other components. RTV silicone rubber is a solvent-free, corrosion-free, single component room temperature vulcanized silicone rubber. It has a long storage period, stable performance, and can be used to bond common metal and non-metallic materials, so it is suitable for bonding and sealing between various metals, metal and non-metallic materials.

Purpose:

RTV silicone rubber (room temperature vulcanized silicone rubber), as a bonding, sealing, insulating, moisture-proof and shockproof material, is widely used in bonding and sealing of electronic components, semiconductor materials, electronic appliances and other equipment, waterproofing and sealing of electric heaters and electronic instruments, and potting of electronic components. Such as the sealing of electric heating end, the bonding of small motor magnetic tile and metal shell, the bonding and sealing of automobile lamps, optical instruments and lenses, the bonding of electronic instrument shell, the insulation protection of motor, the bonding and sealing of electronic components, etc.

Performance characteristics:

It has good bonding performance, excellent electrical insulation performance of the cured product, and moisture and shock resistance functions. Non toxic, non polluting and non corrosive. It has good electrical insulation and arc resistance, aging resistance, moisture resistance, and good bonding performance. Applicable to - 60 ℃~200 ℃ working temperature.

usage method:

After the components are generally cleaned and dried, the product is extruded from the metal hose for sizing. When the rubber contacts the moisture in the air, it is solidified from the surface to the inside. The total solid time is no longer than 24h.

matters needing attention:

1. RTV silicone rubber (room temperature vulcanized silicone rubber) can be cured at room temperature first, and then treated in a wet oven at 50~100 ℃ for 4~8 hours to remove low molecular substances and fully cure to ensure the performance of the rubber.

2. After the product is used, the rubber tube should be tightly covered, and it can be stored for reuse.

3. When this product is used for potting, the one-time accumulation thickness should not be too large. If it is ≥ 3mm, the method of layered pouring and gradual vulcanization can be used. The greater the accumulation thickness of liquid rubber, the longer the complete curing time.
