Detailed product description
Product Introduction
Shin-Etsu KE441W is a one-component silicone adhesive sealant. It is a silicone sealant with good fluidity in general industry.
The characteristics of deoxime type make it have the smell of oxime type gas during the volatilization process, and it is corrosive to copper-based metals, so it cannot be used for contact or indirect contact Parts of copper-based metals. But oxime-type silicone gel has stronger bonding performance and preservation sex. Therefore, there may be unexpected consequences when used in parts that do not contain copper-based metals. Good bonding effect.
Shin-Etsu KE441W is a low-viscosity silicone sealant. After curing, the hardness is Shore A: 25. It is relatively wear-resistant and environmentally resistant, resistant to acid and alkali corrosion, and has good shock absorption.
Product Application
Shin-Etsu KE441W 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 KE441W 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 is almost Will not spoil as they have excellent UV, ozone and moisture resistance.
5. Processability: These products are easy to use as they can be processed from their tubes ( or other container) and use it immediately.

ReadWhat you get with the material
We are not just shipping you a drum
A grade on its own rarely solves the problem. These are the four things we do around it.
Selection support
Tell us the substrates, the process window and the failure you are trying to avoid. We narrow the field before you order anything.
Process designPrototyping and pilot runs
Bonded samples and pilot batches of 200–500 pcs on our own dispensing and curing equipment, so process questions are answered before mass production.
Prototyping & pilotCross-border supply, DDP
Destination clearance, local labelling and destination-language SDS are set up by us. Class-restricted goods are routed at quotation time, not discovered at the border.
Cross-border supplyDocumentation chain
Which document, issued by whom, covering what, and notification when it changes. We pass manufacturer documentation through unchanged.
Material substitutionCommon questions
Before you send the enquiry
Yes. Tell us the grade and how you intend to use it, and we will send the manufacturer’s current technical data sheet. We pass manufacturer documentation through unchanged rather than reissuing it under our own name.
No — and you should be careful with anyone in our position who says they do. What we supply is the document chain: which document exists, who issued it, what it covers, and notification when it changes. Compliance statements come from the manufacturer, not from us.
That is one of the most common reasons engineers contact us. Equivalence is a ladder, not a yes/no answer — some claims are backed by a matching data sheet, others only by chemistry family. We will tell you which rung a given substitution sits on before you commit to it.
Packaging sizes shown on this page are the standard units for this grade. Sample quantities for evaluation are handled case by case — tell us the trial you are planning and we will scope it with you.
Tell us what you are bonding
Substrates, process window, and the failure you are trying to design out. An engineer answers, not a form.
We do not issue compliance certificates. We supply the material, the manufacturer’s documentation, and the engineering judgement in between.
