Thermally conductive potting I. Features two-component silicone thermal potting, in a wide range of temperature and humidity changes, long-term, reliable protection of sensitive circuits and components, has excellent electrical insulation, moisture and some waterproof retardant properties, can withstand environmental pollution, to avoid damage due to stress and vibration and humidity and other environmental factors on the product caused, especially for heat dissipation requirements of the potting material good product. The product has excellent physical and chemical properties. 1: 1 mixture room temperature curable or heat fast curing, minimal shrinkage, thermal curing process without a solvent or cured hold byproducts, having repairability, can be deep solidified into an elastomer. Second, the typical application of thermal insulation thermal potting potting protection applies to electronics, power modules, high-frequency transformers, connectors, sensors and electric components and circuit boards and other products. Third, the technical parameters of the project (A / B) W (A / B) Appearance (A / B) Dark Grey / White White / White Viscosity CP 2500 ± 10% / 16000 ± 10% share (25 ℃) 1.7 mixing ratio (weight ratio) 1: 1 mixture Operating time 25 ℃ 2 hours Cure conditions for 8 hours / 25 ℃ 40 分钟 / 65 ℃ Hardness A (Shore) 50 ~ 65 Volume resistivity Ω · cm 1 × 1015 linear expansion coefficient [m / (m · K)] 1 × 10-4 Thermal conductivity w / mk 0.8 Dielectric strength KV / mm 10 Temperature range ℃ -55 ~ 200 Note: The above performance figures are measured under the conditions of our company, for reference only. The use of methods and precautions 1, the two components should be sealed and stored separately, so now with the existing, mixed plastic materials should be run out of time to avoid wastage. 2, based on the weight ratio of A: B = 1: 1 ratio is mixed and stirred evenly to sizing. Note that in order to ensure good performance of the product, A and B components during the 1: 1 mixture of the past, after their needs, stir, and then sampled for weighing ratio, then stir with a good rubber then applied potting. 3, operation time and product formulation related things, mainly affected by temperature, high temperature will accelerate the curing speed, operating time will be shortened, low temperature curing speed will be slow, the operating time will be extended accordingly. 4, mixing sufficient thermal potting, or poured directly into the container to be cured, can be cured at room temperature or heat curing. If Glue highly thick and appearance of the product requires a high after a good potting cured, it can deal with its vacuum pump according to the situation, put the mixture into the vacuum container, degassing at 0.08MPa at least five minutes, the bubbles were withdrawn after potting. 5, after a certain storage time will be layered compound precipitated. Please stir before use, product performance is not affected. 6, the product is non-dangerous goods, but to prevent splashing into eyes, not swallowed. 7, specific materials, chemicals, curing agents and plasticizers can inhibit the thermal potting (silicone) curing, including: Organotin and other organometallic compound containing sulfur tin catalyst silicone rubber, polysulfide material, polysulfone or other sulfur-containing materials amines, amine-containing urethane or unsaturated hydrocarbon plasticizers articles some flux residues Note: If an object or material will cause obstruction cured if there is doubt recommended for small-scale tests to determine the suitability of this application. If the experiment does not appear in curing or local not curing phenomenon, you can rest assured that use. V. Packing / W: 25KG / barrel; 200KG / barrel metal pail six, storage 1, the product should be sealed and stored in a cool, dry place to prevent contact with moisture in the air glue, the storage period at 25 ℃ 12 months. 2, these products are non-dangerous goods, according to general chemical transport can be.
