Electronic potting Shijiazhuang anti-shrinkage epoxy electronic potting

Shijiazhuang anti-shrinkage epoxy potting electronic manufacturers supply anti-shrinkage epoxy electronic potting, Phone: 13930464248 Contact: SUN towards welcome to inquire. A anti-shrinkage epoxy electronic potting Features: In addition to having the general characteristics of epoxy potting material, the special includes: 1, thermal conductivity and thermal performance is excellent 2, good flexibility, high mechanical strength. 3, linear expansion coefficient, anti-shrinkage 4, good flame retardant properties. 5, low viscosity, good permeability. Two purposes: for dry-type transformers and high thermal conductivity, high temperature and freeze-resistant electronic products potting three appearance and characteristics: Item 107A 107B Viscosity (40 ℃ cps) 11000-15000 40-50 Color Black ( or specified) light yellow four, use of technology: 1, A material preheated to 60 ℃. 2, For the potting of electronic components at 100 ℃ heating, get rid of moisture. 3. The proportion of anti-shrink epoxy electronic potting A, B material mixing, the mixture was evacuated first to observe the surface without air bubbles, and then the electronic components for vacuum casting. 4, casting is completed, turn oven for heating solidified. 5, anti-shrinkage electronic potting epoxy curing process: 75oC for 2 hours + 95oC 1 hour + 110oC for 2 hours (can be adjusted according to user needs to enter) 6. The curing process for curing, after curing components With the oven to cool before they can be removed.
