Addition type silicone sealant
HT-9801A/B
HT-9801 A/B is a two-component silicone addition system thermalconductivity encapsulant, has the following characteristics:
1, plastic material at room temperature under the mixed storage time is longer, but in the heating conditions can be fast curing, especially for automatic production line.
2, temperature resistance, high temperature resistance, good. After curing (-60 ~ 250) temperature range, the silicone rubber was maintained and the insulation performance was excellent.
3, the curing process of small shrinkage, has a better waterproof, moisture and anti aging properties.
A typical use: it is used for high power electronic components, for cooling and temperature resistant sealing protection requirements of high power module and a circuit board. Such as encapsulating module, automotive HID lamp power supply module, auto ignition system power supply module, solar panels, transformers, sensors and so on.

Three, the use of technology:
1, according to the weight ratio of 1:1 two groups into the mixing tank mixing uniform.
2, the mixed good adhesive materials are filled in the sealing device, generally without the vacuum deaeration, if you need to get the high thermal conductivity, it is recommended vacuum deaeration after reperfusion.
Four, note:
1, plastic material should be sealed storage. Mixed good adhesive should be used to avoid causing waste.
2, this product is a non dangerous goods, but not the entrance and eye.
3, after a long time, the filler will be in the plastic settlement. Please use after mixing evenly, do not affect the performance.
4, glue liquid contact with the following chemicals will make the glue is not cured:
1) N, P, S organic compounds.
2) Sn, Hg, Pb, As plasma compounds.
3) containing alkynes and multi vinyl compounds.
Five, packaging specifications: 50KG/ sets (A 25kg/ 25kg/, B plastic bucket)
Six, storage and transportation:
1, a cool dry place storage, storage period is 12 months (25 C).
2, such products are non dangerous goods, can be transported by the general chemical.
3. The A and B components of the colloid are required to be sealed and kept carefully in the transportation process!
4, more than the preservation period of the product should be confirmed that there is no exception to use.
The above performance data is the typical data measured in the laboratory environment of the temperature 25, humidity 70%, only for the use of the reference, and can not guarantee the full data in a specific environment, please customers in the use of experimental data as the standard.
