Description
Liquid RTV2 Silicone GRC Casting Silicone Rubber for Moulding MaterialCondensation Molding Silicone is generally named as two-parts silicone rubber that is vulcanized
at room temperature, and used for model designing work of all kinds of products with simple
or intricate patterns, such as artificial stones, craft stones, gypsum crafts, GRC/GFRC, GRG,
fireplaces, fountains, ornaments, resin crafts, resin marble works, shoe soles, Art sculptures,
decorations, candles, soaps, PU, furniture moldings, etc. With good resistance to deformation, heat, acid, alkali and expansion, finished silicone molds have very good performance in reproduction process and fine details on designing models

Condensation molding silicone rubber is a kind of flowing liquid, and it consists of two
components,
part A is a flow-able liquid silicone rubber, part B is the curing agent.
1. Firstly, after your previous work of dealing with the original model, take some liquid silicone
rubber, add 3% curing agent of the amount of silicon and mix them evenly.
2. Then after vacuum pumping the mixture, you can pour it into the mold frame.
3. The silicone mold will be cured in 3 to 5 hours.Liquid RTV2 Silicone Grc Casting Silicone Rubber for Moulding MaterialOTT New Material Co., Ltd. is located in Guangzhou, Guangdong. We are a leading professional silicone material manufacturer, integrating the R&D, production and sales. Main products are Condensation molding silicon rubber, Addition molding silicone rubber, Addition electronic potting silicone rubber,Condensation electronic potting silicone rubber,leather printing roller silicone rubber,LED strip light silicone rubber,human casting silicone rubber,etc over hundreds kind of silicone rubber and related products. Our customers are from all over the world. If you are interested in our products, please feel free to cont act us for further information.1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is: #A, Please choose the right liquid silicone according to your products. #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use. #C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
