Tin-based silicones, also called condensation-cure silicones, are two-component materials which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicones can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.
Product Feature of Electronic Potting Silicone Rubber HY-9055 silicone rubber is a kind of low viscosity, Inherent flame resistance, two components addtion cured potting silicone with heat-conducting. It cures with both on room temperature and heated temperature. It has the feature of the higher temperature the faster of the curing time. It can be applied to electronic components for insulation, waterproofing, fixed and flame retardant. It mainly applied in electronic components surface with materials of PC(Poly-carbonate)PP ABS PVC, etc. and metal materials. 2. Typical Application of Electronic Potting Silicone Rubber HY-9055 electronic potting silicone rubber could be applied to - high powered electronics, - DC/DC module and circuit board which requires heat dissipation and high temperature resistance. -It can be broadly used for LED screen, Wind Power Generator, PCB substrate, etc. 3. Technical Guidelines of of Electronic Potting Silicone Rubber a, Pls put part A and part B in separate container and stir evenly before mixing the two part together. b, Mixing Ratio: part A: part B = 1:1 c, Deaeration the mixture in vacuum pump under 0.08 MPa for 3-5 minutes.Then the mixture could be used for pouring. Note: The thickness of the silicone affects the curing time. If the silicone used is a little thick,then the curing time will be a little longer.The temperature also affects the curing time.When in lower temperature, we suggest customers appropriately heat the mixture to accelerate vulcanization. With temperature of 80?100?, the silicone will cure in 15 minutes; while in 25? room temperature, the silicone will cure around 8 hours.
The pad printing silicon rubber is a carrier which transfers the patterns from the steel plate onto the products' surface. The pad printing silicon rubber has the advantages of good printing effects,good quality,good resilience and without any impurity. Pad printing silicon rubber is mainly applicable to the printing of irregular patterns on plastics toys,electronplating products,electronic toys, trademarks,artwork gifts ,stationeries etc. Applications of liquid pad printing silicone rubber Pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys and trade makers . Pad printing silicone rubber as a carrier which transfer patterns on the steel plate to the toys products surface. 2. Features of liquid pad printing silicone rubber a. resistance to deformation, high-temperature b. high printing times c. good aging resistance d. exceptional elasticity e. great printing effect 3. Operation Instructions of liquid pad printing silicone rubber Pad printing silicone rubber is two-component silicone, part A is liquid silicon rubber, part B is catalyst. The usual mixture of silicone rubber and catalyst is 100: 2 or 100: 3. E.g. we take 100g of liquid silicon rubber and 2g-3g catalyst, mix them and pour it to your mold. A fter 2-4 hours, you will get a Pad printing silicone rubber. HY-918 with the advantages of high temperature resistance, abrasion resistance, good printing effect, etc. , which made of top-quality raw material due to adding American Dupont Teflon high-temperature resistance new material, is processed through high-temperature machining. The product is mainly applicable to plastics toys, electroplating products, electronic toys, trademarks and irregular pattern printing. The silicon pad is a carrier which transfer printing the patterns on the steel plate onto the toy products' surface. HY-918 is a kind of silicone rubber to make the printing pads for plastic toys, craft works, product printing. Characteristics good printing effects good quality good resilience and without any impurity.

Strenghts for platinum cure molding rubber silicone rtv Operation of platinum cure molding rubber silicone rtv Rtv625 is suitable for making moulds for small size products by pouring method; Rtv630 is suitable for making moulds for small or medium size products by pouring and brushing method; 25kg/drum or 200kg/drum
400 1:1 Most suitable for medium sized product 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. 25kg/drum or 200kg/drum
25 Dielectric permittivity(1.2mhz) 3.0~3.3 Volume resistivity(cm) 1.01016 Fire resistance 94-v1 (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.
