Brief Introduction of liquid RTV Silicone Rubber
RTV-2 silicone rubber is generally named as two-part room temperature vulcanized silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
Features of Mold Making Raw Material RTV Silicone Rubber:
Outstanding release properties
High Flowabilty and long woring time
Medium Hardness
High tear resistance
High elasticity for easy removal of complex replica parts

If you need RTV-2 silicone for making molds for concrete stone & gypsum decor, please click the picture below.
1-Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
2-vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available
3-Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.
We are happy with MC RTV-2 silicone rubber and quality. I've also been very happy with your best service, let's continue discussions and work on more. --- Mike (from NY, USA)
100% love the liquid silicone. I will be ordering more this week. ----Kody (from Turkey)
We are very pleased with the quality of RTV-2 silicone rubber and the performance. ------Richard from UK
The RTV-2 silicone rubber has arrived and is excellent------John from Iran
I have selled some RTV molding silicone for my customer, they are very happy, so thank you-----Adam
We are manufacturer, and specialized in manufacturing different hardness, different viscosity silicone rubber series, we are competitive in price with good quality.
Quality Certificate of RTV liquid silicone rubber:
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
