Detailed product description

Product Introduction

Shin-Etsu KE4890G is a one-component silicone adhesive sealant in gray paste form, which is a low-molecular silicone-reduced product. It has international UL flame retardant level certification. Has good pressure cracking properties.

The characteristics of dealcoholization make it have low odor and low corrosion during the volatilization process It produces neutral volatiles and is non-corrosive to electronic components. Safe and harmless to the environment.

Shin-Etsu KE4890G is a medium-to-hard hardness silicone sealant. After curing, the hardness is Shore A: 50, which is relatively wear-resistant and environmentally resistant, resistant to acid and alkali corrosion, and has good shock absorption.

Product Application

Shin-Etsu KE4890G 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 KE4890G performance introduction

  1. Can maintain stable heat-resistant and cold-resistant electrical properties in places with unstable temperature and humidity;
  2. < li style="line-height: 1.5;">It can be used in a wide temperature range and maintains good performance at -50~250閳? /li>
  3. It has good resistance to ultraviolet rays, ozone, smoke and moisture, and is especially suitable for outdoor use ;
  4. Excellent in shock resistance and chemical properties, it can effectively protect electronics Component.
  5. Weather resistance: One-component room temperature vulcanized silicone rubber is resistant to long-term exposure to the outdoors. They are virtually impervious to deterioration as they have excellent resistance to UV, ozone and moisture.
  6. Workability: These products are easy to use as they can be processed from their The tube (or other container) pops out and is used immediately.
