Electronic potting silica gel
It can be applied to PC (poly carbon), PP, ABS, PNC and other materials and metal surfaces. It has excellent adhesion performance and fully meets the requirements of European ROHS directive. The electronic potting adhesive is resistant to high and low temperature (- 50c-2500), water, oxygen and weather aging. It can keep its elasticity at low temperature (- 50). It also has the properties of corrosion resistance and quenching, and has strong adhesion; It has a strong fixation effect on Qingguang panel, solar cell and electronic components. It is used as the sealing material of electronic and electrical components. It has the nature of anti shock and weather resistance and is used as the sealing, bonding and coating materials of electronic components. It also has the functions of moisture-proof, insulation, shockproof and natural resistance. Backlight, high voltage module, conversion line HD lamp module power supply, automobile power supply network transformer, communication element, household electricity, solar cell, solar cell transformer and electronic element can be well responded to
Operation method of electronic sealer:
1. Weigh the weight ratio of component A and component B: measure correctly according to the correct mix proportion (weight ratio). If there is a large error in the measurement of mix proportion, the product characteristics will not be displayed well
2. Mix semi-uniform silica gel and curing agent: mix component A and component B semi uniformly. When mixing AB glue, pour the part with less proportion into the part with more proportion for mixing. When mixing the resistance, it should be smooth and not too decisive. Hold for about 3 minutes. Mix the bottom, wall and other parts of the container evenly. If not, the curing will be incomplete. The container must be semi glue
3. Vacuumize and discharge bubbles: move to the vacuum box quickly after fully mixing. The bubbles involved in the material mixing will make the liquid level rise, and the liquid level will fall again after the bubbles break. The vacuum degree, the viscosity of the glue and the requirements of the product are fixed (generally 2-4 minutes for defoaming). If there is no vacuum machine, the glue can be placed for 5-20 minutes in the clockwise direction for 2-3 minutes
4. Pour in the sealant and wait for curing: inject the necessary amount of sealant, and at the same time pay attention not to get involved in bubbles. After flowing into the bottom along the inner wall of the shell, let the glue level rise slowly and solidify at the set temperature

Features of electronic potting adhesive:
1. Low viscosity, good fluidity, suitable for the molding of complex electronic accessories, also can be used for manual filling or dispensing machine, filling machine operation.
2. The soft silicone rubber is formed by curing, which has excellent impact mitigation performance, reduces the internal stress of components and protects components.
3. It can be cured at room temperature or heated, suitable for a variety of operation processes.
4. The flame resistance can reach UL94V-0, which fully meets the requirements of European ROHS directive.
5. Dampproof and waterproof up to lpx7
6. Good thermal conductivity, which can play a good role in heat dissipation and product protection.
7. The high transparent filling silica gel can clearly see the internal structure of the product, which is more conducive to the reuse of damaged components after repair.
