Electronic potting glue is divided into: addition molding electronic glue and condensation type electronic silicone
Addition molding electronic si is divided into:93, 94 series and 90 series A / B components conventional ratio 1:1, room temperature curing ,The 93 and 94 series are the same system, both are added transparent electronic potting silicone 93 series model: 9300 (the surface is somewhat sticky), 9305, 9310, 9315, 9325 Color transparent, suitable for ordinary potting, waterproof and moisture-proof
The edge is shock-resistant and has no tensile and tear resistance. Only the newly developed 9345# has a certain toughness and is not easy to tear.
94 series models: 9400, 9404 two models, 94 series viscosity is better than 93 series
Viscosity contrast: 9405 > 9400 > 9300 9405 is the softest
90 series models are: 9015, 9025, 9035, 9045, 9055, etc. Colors are white and gray, mostly used for potting of electronic components, waterproof and moisture proof Insulation and shock resistance, the 90 series has a certain thermal conductivity and flame retardant effect.
There are two models of condensation electronic silicone: HY-210, HY-215 Both models have a hardness of 15 shore A, and A/B components have a ratio of 10:1.
210 color: just made it is transparent, it will be slightly turbid or red for a month or so.
215 color: black
