Various grades of powder styrene butadiene rubber asphalt modifier
Application fields
Various grades of styrene butadiene rubber powder asphalt modifiers are mainly used as building waterproof material. Such as self-adhesive rolling, non-curing waterproof coating, reactive self-adhesive rolling. Some of the high content powder styrene butadiene rubber asphalt modifiers can also be used in the modification of road asphalt.
Product features
Styrene-butadiene rubber powder asphalt modifier, which is polymerized by styrene and butadiene at low temperature (5) and it is born by the characteristics of waterproof rolling material and non-curing waterproof coating.
When mixed the bituminous waterproofing roll with XY-5 styrene butadiene rubber powder, because of the active functional groups of powdered styrene butadiene rubber itself, it makes waterproof material to produce a special activity, making the material in the solidification process of Portland cement, with silicate cement of chemical compounds, producing chemical combination, forming a strong cohesive force and improving the waterproof materials and cement bond. At the same time, powdered styrene butadiene rubber can also greatly improve the performance of low temperature and tensile properties of the waterproof materials.

Pad printing silicon rubber usages:
pad printing silicone rubberis mainly use forprinting irregular patterns on plastic toys, shampoo, pen, glass , electroplating toys and trade makers and so on .
Pad printing silicon rubber description
silicone rubber and curing agent evenly.
Step two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: the time for vacuum-pumping should be less than 3a5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step three: pouring the vacuumed mixture into the original mold slowly,
Shelf life for pad printing silicon rubber
8~10months, when stored in a dry & cool place under the room temperature 25.
Packing for pad printing silicon rubber
20kgs/drum vacuumed packing
Faq of pad printing silicone rubber:
Why the silicone pad did not absorb ink?
Any silicone pad or liquid silicone rubber could absorb ink well. If large patterns or big letters need to print, the printing pad can absorb ink well. For small letters, please do not use hard silicone pad, as it can not absorb the printing ink thoroughly from the steel plate.

s than 10 minutes.
Note: the time for vacuum-pumping should be less than 3a5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Shelf life for silicon rubber for mold making
10~12months, when stored in a dry & cool place under the room temperature 25.
Faq silicone rubber for mold making:
Why is the silicone mold oily?
The molding silicone rubber itself doesn't contain any oil, so it won't be oily. If the mold is oily, it may because you add compound silicone oil which is the compound of silicone oil and white oil. But the white oil is not silicone oil but a kind of petrochemicals.

(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.
