SANDAO thermal rtv silicone rubber widely-use for screws-1

One-component organic silica gel SD704

One-component organic silica gel SD704 is neutral one-component organic silica gel , absorbs moisture in the air at room temperature. No poison, no pollution, no corrosion. The single-component organic silica gel has good electrical insulation and arc resistance, aging resistance, moisture resistance and good bonding performance. It can be used in the range of-60 ℃-200 ℃ for a long time. Long storage period, stable performance, can be bonded to common metal and non-metallic materials, this one-component organic silicon gel is suitable for bonding and sealing between various metals, metals and non-metallic materials.

Application

As adhesive, sealing, insulating, moisture-proof and shockproof material, this one-component organic silica gel is widely used in bonding and sealing electronic components, semiconductor materials, electronic appliances. For sealing and waterproof of electric heater, electronic device, also can be used in potting of electronic component etc.
Such as electric heating end sealing, small motor magnetic tile and metal shell bonding, automotive lamp, optical instrument and lens bonding sealing, electronic instrument housing bonding, electrical machinery insulation protection, electronic components adhesive sealing, etc

Storage

It can be used for a long time in the temperature range of -60 °C----200 °C. Packing specification: 45 g/tube 100 g/tube 310 ml/cartidge

Use instructions

After component drying and clearing, the single component organosilicon gel is extruded from the metal hose, and the compound contacts with the moisture in the air, solidifying from the outside to the inside, the maximum solid time is not more than 24 hours.

Caution

1. For thermo-resistant components, first curing at room temperature, then put in 50 ℃ -100 ℃, in a damp oven for 4 hours, remove the low molecular weight, fully solidify, to ensure the properties of the adhesive.
2. his one-component organic silica gel should be sealed tightly after use and can be stored and reused.

Packaging and preservation

Packing specification: 45 g / 100g / 300ml per pcs

storage: this product should be stored in a cool and dry environment, can stored for one year.
