(pls note all data of pcb electronic potting silicone rubber with black color above is in 25c with 55% humidity conditions. We don't guarantee a same date if testing under different conditions, or when data was regenerated).
Warm tips for for pcb electronic potting silicone
1. Sealing package for storage. The mixture should be used up at once to avoid wasting.
2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.
3. When it gets stratified after a period of storage, please mix hy-210# evenly before using,
It does not affect the performance.
Shelf life and transportation
1. Twelve(12) months when stored at 25c in original unopened packages.
2. This is a non-dangerous product, it can be transported as general chemicals.
3. Products exceed the storage life should be confirmed normal before using.
Technical guidelines
1. Pls put part a and b in separate container and stir evenly before mixing the two
Parts together.
2. Mixing ratio part a:part b is 10:1
3. Bubble release if necessary, deaeration the mixture under 0.08 mpa for 3 minutes.
4. Hy-215# is cured at room temperature, so pls put it under room temperature after
Pouring. It comes to next process when basically cured, and it takes about 24 hours
For completely cured.

Addition cure silicon rubber for artificial stone products advantages:
Flexible, high and low temperature resistance, resistance to ultraviolet radiation, environmental protection, water repellent, good air permeability, good insulation, shrinking smaller
Addition cure silicon rubber for artificial stone products points of attention:
1, prone to poisoning, can not mix with condensation, ionic compounds containing n, s-, p, organic matter and of sn, as, hg, ph., easy molding plastic poisoning, resulting in the phenomenon of not curing.
2, comparing with condensation cure silicone, addition cure silicone's adhesive properties to be worse.
3, addition cure silicone affect by temperature greatly when cured under room temperature.
4, addition cure silicone is easy to poisoning, please clean the tools which are used for condensation silicone rubber, so that it can avoid poisoning.
Its fobidden to add the pigment or powder to addition cure silicone rubber arbitrarily, its easy to make the catalyst to be poisoning.
5, addition cure silicone rubebr has two-component, the component a and component b, please pay attention to clean the component a containers before using for the component b, and vice versa
6, in order to avoid the hardness change, we should mix the component a and component b according to its mixing ratio strictly, no atter its 1 : 1 or 10 : 1.
