Product Description

Flame-retardant &Thermal Conductive Industrial Silicone Sealant


Product Feature


Guibao 4815ZL is a condensed single-component room temperature vulcanized silicone rubber composed of silicone polymer, reinforcing filler, addition agent, cross-linking agent, etc. Its characteristics are as follows:


Single-component packaging, easy to operate when used;

Room temperature curing, non-poisonous, non-corrosive;

After fully curing, it maintains its elasticity for a long time in the range of -50 ° C to 200 ° C;

Excellent electrical insulation performance, arc-resistant corona and impact resistance, long-term effective protection of electronic components;

Good water resistance, excellent aging resistance;

Excellent adhesion, maintain long-term sealing performance;

Excellent flame retardant performance, up to V-0 level.

Widely used for bonding and positioning of various electronic appliances, and functions as dampproof, shake proof, insulation, weather-resistant;

Used for bonding and sealing of high voltage components such as various power supplies, inverters, etc;

Used for seal protection of electric vehicle BMS controllers.

Application Method and Notes


Clean and dry the surface to be adhered, extrude the product from the packaging tube, apply it evenly on the part, and trim it before the sealant has been vulcanized to remove excess sealant.

Note that the thickness of applied sealant should not exceed 6mm. Avoid contact with the eyes during application. It should not be sealed during application and curing. Maintain a good ventilation environment.

After each use, it should be quickly sealed to prevent the remaining sealant in the tube from contacting with moisture in the air to solidify.
