Transparent silicone products with silica - glass, special silicone solar concentrator
Product Description
QJ-2558A / B, QJ-2558A / B is a platinum complex catalyst curing two-component transparent liquid silicone rubber, the basic compound, crosslinking agent, catalyst, additives.
Purpose
Transparency requirements for forming a high after the field, such as solar concentrator glass, solar lens and so on.
Features
Strong adhesion, high transparency, high-temperature, low shrinkage, the product does not contain heavy metals and aromatic solvents, curing process does not produce volatile substances, environmental protection and the human body without toxic effects.
Use
The A and B mixed at a 1:1 ratio of compression molding, 150 ℃ × 5MINS vulcanization molding, depending on the thickness of products, extend or shorten the curing time.

Notes
1 can not access with N, P, S and other organic matter, Sn, Pb, Hg, Bi, As and other ionic compounds, including alkynes and vinyl compounds, in order to avoid poisoning the platinum catalyst can not be cured.
2. A mixed with B, must be used within 12 hours, in principle, will slow crosslinking, which led to failure, if the ambient temperature is high, should attract even more attention.
