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.

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.
