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.

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.
Condensation silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
1. Application of rtv liquid moulding silicone rubber :
liquid molding casting silicone rubber is mainly applied for making various
molds,such as reproduction of poly resin, epoxy, polyurethane-polymer, plaster,
gypsum casting and moulding, soaps, candle & lighting, architecture, decorative arts and crafts, plastic toy, gift and stationery, big statue, cultural relic product, etc.
2.Features of rtv liquid moulding silicone rubber
a. low viscosity, exceptional fluidity and easy operation:21000 cps suitable for pouring
b. resistance to deformation, high-temperature 220 degree centigrade
c. acid, alkali and aging-resistance
d. low shrinkage< 0.2%
e. good tensile strength 36 2 (kgf/cm)
f. high reproduction times
3. Operation tips of rtv liquid moulding silicone rubber
a. adding too much silicone oil will destroy the molecular of silicone rubber, which will cause a decrease of the tensile and tear strength of the mold and deformation may occur.
b. remember to take the proper silicone rubber to make the mold for suitable products. for products with delicate and complicated patterns, you are expected to use soft silicone to make molds. While for products with easy and smooth patterns, you should choose hard silicone rubber.
Plus: We have free CD on how to operate for our customers enclosed with product package.
