Detailed product description
Product Introduction
Shin-Etsu KE4897 is a one-component silicone adhesive sealant , is a low molecular weight silicone product. It is a silicone sealant with good fluidity for general industrial workers.
The characteristics of dealcoholization make it in the volatilization process It has the characteristics of low odor and low corrosion, produces neutral volatiles, and has no corrosion to electronic components. Safe and harmless to the environment.
Shin-Etsu KE4897 is a high-viscosity silicone sealant with a hardness of Shore A: 40 after curing. It is more wear-resistant, environmentally resistant, and acid and alkali resistant. corrosion.
Product Application
Shin-Etsu KE4897 is widely used in electrical insulation and has a wide applicable temperature range. Requirements for bonding, sealing and fixing of various electronic components and mechanisms; products with more such requirements. It has high and low temperature resistance, anti-aging, shock absorption and buffering, easy maintenance and excellent sealing and moisture-proof properties. Such as: electrical appliances, solar cells, batteries, hybrid integrated circuits, TC fans and components, electronic products, power, sensors, fluorescent lamps, membrane switches, LED display panels, electronic equipment, aviation systems, liquid crystal displays, cathode ray tubes, etc.
Shin-Etsu KE4897 performance introduction
1. Electrical properties: They have outstanding electrical properties in terms of volume resistivity and voltage resistance.
2. Heat-resistant and cold-resistant: they can be used in a wide temperature range (-40°C to +180°C).
3. Impact resistance: Cured rubber has excellent rubber elasticity and absorbs vibration and impact.
4. Weather resistance: One-component room temperature vulcanized silicone rubber will hardly deteriorate when exposed to the outdoors for a long time because they have excellent UV, ozone and moisture resistance.
