Frequently asked questions for Silicon rubber for manual mold What should we do when the air bubbles appeared in the process of mold making ? To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles. 25KG,200KG/DRUM PACKING Delivery Lead Time : within 3 days after payment confirmed in bank
Silicon rubber for molding making is primarily intended for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts, crafts industry, a large statue buddha, relievo furniture, furniture decorative materials, statues buddha artifacts copied, building decoration materials, large-scale cerment mold, artificial fossils factory, europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on. Silicon rubber for molding is white or red flowing liquid with general hardness of 22-50A centi degrees after curing. Molding silicon rubber is a kind of elastic silicon rubber whose features with resistance to deformation,high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation. Silicon rubber for mold making operationsú¦ If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed. 25KG,200KG/DRUM PACKING Delivery Lead Times : within 3 days after payment confirmed in bank.
Silicone rubber for pad printing operation instructions: Pad printing silicone rubber is two-component silicone, part A is the liquid silicone rubber, part B is the catalyst. The usual mxing ratio for silicone rubber and catalyst is 100 : 2-3, eg. we take 100grams of liquid silicone rubber, then we add 2-3 grams catalyst, mix then evenly and pour it to your mold. Then after 2-4 hours, you will obtain a printing pad. Frequently asked question of pad printing silicone rubber: The reasons why the silicone pad has a short service life are listed as follows: (1)The problem caused by inappropriate filtration of silicone rubber, and impurities in the packaging process due to the uncleanness of barrels and bags. (2)The short service life of the silicone pad has a close relationship with the adding amount of silicone oil. The more the silicone oil added, the softer the silicone pad will be. The silicone oil will destroy the molecule of the silicone rubber, thereby bringing about the non-durable and easy ageing of the silicone pad.

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.
