Silicone Gel Thermal Conductive Potting for Washing Machine Circuit Board Waterproof Sealing

Product Description

Silicon gel is a special silicone rubber, which is divided into A and B components, mixed in 1:1 ratio and then cured. Before solidification, it is a liquid, and after solidification, it becomes a sticky, soft and elastic object on the surface. It is widely used in circuit board sealing, filter slot sealing, smart water meter sealing, and internal component sealing of difficult to stick plastic shells

FEATURES & BENEFITS
Soft, low durometer
Low viscosity
Room temperature or accelerated heat cure
Good thermal conductivity
Mix ratio 1 to 1
Low internal stress during
thermalcycling
Highly flowable for filling smallgaps and fast processing
Good heat dissipation
Prevents water ingress
Electrically insulative
Low total cost of ownership

COMPOSITION  Two- part Polydimethylsiloxane Package 10kg/pail for each part Two-part, 1 to 1 mix ratio, low viscosity encapsulant
APPLICATIONS
Jome chemical JOMS 5230-6 Low Stress Encapsulant has a very low hardness andviscosity to minimize internal stress generation, fill   small gaps, and improvemanufacturing speed for complex and high    volume electronic devices.  Excellentflame  resistance and  protection against water  ingress  that  improve  the  safety  andreliability under  harsh outdoor environments such as:Power Conversion Devices (Inverters, Converters, Driver) Junction Boxes Automotive Electronics Modules

PREPARING SURFACES
In applications requiring adhesion,priming  will  be  required for manyof  the  silicone encapsulants.  Forbest  results,  the primer should beapplied in a very thin, uniformcoating and then wiped off   afterapplication.  After application,  itshould  be thoroughly cured   prior   toapplication   of   the siliconeelastomer.  Additional instructionsfor primer usage can be found    inthe    information  sheets specific tothe individual primers.
