VS-TP1501 Thermally Conductive Silicone Potting Compound



Description

VS-TP1501 is a two-component 1:1 heat-curing silicone heat-conductive potting adhesive, which cures at room temperature or after heating to form elastic heat-conductive silicone rubber. It is specially designed for the manufacture of electronic and electrical products and modules, such as the potting protection of high-power power supply modules, frequency converters, sensors, etc., and the connection and fixation between on-board electronic devices and PCBs.



Features

• Operating temperature: -40℃~+200℃
• Excellent mechanical properties and ductility
• Excellent thermal conductivity and aging resistance
• Low viscosity, self-leveling, excellent seam drilling ability
• Low modulus, low stress, good adhesion to metals and plastics

Instructions

• Stirring A and B components separately
• Mixing the well-stirred components A and B at the ratio of 1:1 (either volume ratio/weight ratio can be used)
• The mixed compound is poured into the device to be filled and cured (room temperature or heating can be cured).

Cautions

• In order to ensure the uniform distribution of fillers, component A and component B must be separately stirred before mixing, so that each compound is evenly mixed
• A and B agents will react and cure each other after mixing, so they need to be used after mixing, and can not be used twice after mixing and curing
• When pouring into the protective part, there should be no large debris or other pollutants in the protective part to avoid affecting the adhesion of materials and objects
• Before the material is fully cured, keep other objects away from the material, which may affect the appearance and protective performance of the material
• Keep this product away from the mouth and eyes. If it enters the mouth and eyes accidentally, rinse it with clean water or go to the hospital
• For high thermal conductivity, vacuum defoaming is required prior to perfusion
• In low temperature environment, the curing time will be extended correspondingly

Storage conditions and shelf life

• Products should be stored in the original packaging, keep the lid closed, avoid contamination (temperature: 15℃ < T < 30℃; Relative humidity: RH < 70%)

(temperature: 15℃ < T < 30℃; Relative humidity: RH < 70%

• The shelf life is 6 months from the production date
