One, Introduction: Sclerosis in low-temperature solar power converters dedicated Potting Bicomponent sclerosis is a potting material, after curing it in the dense solid structure, with good flexibility, high thermal conductivity, and protective, waterproof , the role of the Security Chip.

Two, conventional performance:

Test items	Testing methods or conditions	87-3A	87-3B
Appearance	Visual	Black viscous liquid	transparent liquid
Density	25℃ g/cm3	1.5~1.5	1.00~1.10
Viscosity	40℃ mpa·s	7000~11000	20~30
Storage period	Room ventilation	6 months	6 months

　

Three, the use of technology:

Item	Unit or the conditions of	87-3A/87-3B
Mixing ratio	Weight ratio	100:20
Can use the time	25℃，min	0.5
Curing conditions	℃/hrs	25/72或70~80/6~4

• Note :87-3A because of the larger viscosity, the use of the best pre-80 degrees before / 2 hours pre-baking to-thinning, in order to operate.

Four, use: apply to solar energy conversion, sensors, circuit modules, such as mixed high heat of the casting components.

Five,  Characteristics after curing

Six, storage, transportation and Cautions:
1. Such products of non-dangerous goods, as a general storage and transportation of chemicals, product packaging, see barrels of storage period.
2. Please see the product model, and then pigeon-holing; accurate weighing, please give full uniform mixing.
3. When potting impregnation speed not too fast, in order to ensure uniform impregnation.
Seven, packaging specifications: Packing for A: 25KG or B: 5KG.

Note: The above performance data for the product in 70% humidity, the temperature at 25 ℃ typical testing data, only use customer information and can not guarantee that in a particular environment can be achieved when all the data. Please use customers to the measured data.
