Usage of rtv silicone rubber for mold making: molding silicone rubber is suitatble for Product duplication and mold manufacture Application rtv silicon rubber for mold making: 1. toys, gifts 2. decoration, plate engrave 3. human replica, art crafts, 4. resin crafts, unsaturated resin crafts 5. poly resin crafts, candle crafts, plastic crafts 6. stationeries, plaster crafts, Bunddhist statue crafts, etc. Features of rtv silicone rubber for mold making : a. good characteristics of easy-operation b.light viscosity and good flowability c. favorable tension d. low shrinkage e. no deformation f. high temperaure resistance, acid and alkali-resistance and ageing resistance Detaials of rtv silicone rubber for mold making: Place of Origin: Guangdong, China(Mainland) Brand Name: Hong Ye silicone rubber Model Number: HY620#, HY628#, HY638#, HY640# Payment & Shipping Terms of rtv silicone rubber for mold making MOQ: 200kg Price: FOB Shenzhen USD6.2~8.3/Kilogram Package Details: 25kg/drum and 200kg/drum Delivery Time: within 3 days after getting your bank receipt Payment Terms: T/T, L/C Supplier ability: 8 Ton/ day Operations of rtv silicone rubber for mold making: mould silicone rubber is a kind of flowing liquid, and it consists of two component, part A is aflowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the origianal moldel, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix them evenly. Then after vacuum-pumping the mixture, you cn pour it into the mold frame. The sillicone mold will cured in 2~3 hours. Note: the time for vacuum-pumping should be less than 3-5mins, othewise, once the silicone rubber has cross-link reaction during vacuumizing. it will not be operated. FOQ of rtv silicone rubber for mold making: 1. Why does the addition cure molding silicone rubber cures after a long time? 　　In spite of the correct proportion of the curing agent and the silicone rubber, the mold silicone rubber needs a quite long period for curing at the room temperature, because it is can be completely cured by heating up the temperature and stressing. The general proportion of silicone rubber and curing agent is 10:1 and their reactions are as follows: 　　The silicone rubber will be cured in 6 hours at the temperature of 50℃. 　　The silicone rubber will be cured in 2-3 hours at the temperature of 80℃. 　　The silicone rubber will be cured in 30 minutes at the temperature of 100℃. 　　The silicone rubber will be cured in 15 seconds at the temperature of 200℃. 2.How to deal with the mold which has a dry surface and a non-dry internal layer during the use of the silicone rubber? 　　The molding silicone rubber, which belongs to the condensation cure silicone rubber is cured by absorbing the moisture in the air. During the mold making process, the water content in the silicone rubber is dried but not adding supplementing appropriate amount of water, so the above phenomenon arises. The solution is that: the phenomenon is not a quality defect; It arises because the water content is not well controlled in order to prolong the shelf life of the silicone rubber; proper amount of 0.05% water is enough to be added into the silicone rubber for even mixing during use.
