Silicone Rubber for Concrete Stamp Moulding: Discover the superior quality of our Durable, Flexible Liquid RTV2 Silicone. Perfectly engineered for precision and resilience, this product guarantees optimal performance for all your stone stamp molding needs.
Step 1: Prepare the Original Molds
Ensure your original molds are flawless. Secure them firmly on a board, creating a stable base. Then, use four additional boards to enclose the original molds securely, providing a reliable framework for your silicone work.
Step 2: Accurately measure and mix 100 grams of Part A silicone rubber with 3 grams of Part B curing agent. Blend thoroughly until the mixture is consistent and ready for application.
*Important Notes: Mold-making silicone rubber is a fluid compound consisting of two parts. Part A is a flowing white liquid, while Part B serves as the curing agent or catalyst. Adhere strictly to the following procedure:
1. Precisely weigh both components using an electronic scale. Incorrect proportions, such as excess catalyst, will accelerate the curing process, complicating the procedure and limiting your working time.
2. Ensure thorough mixing of Part A and Part B for uniformity. Inadequate mixing can lead to partial solidification, reducing mold life and resulting in unnecessary waste of silicone rubber.
Step 3: Vacuum Pumping (Optional)
This critical step, if performed, should be completed in under 10 minutes. Exceeding this time can trigger a cross-linking reaction, preventing further processing.
Step 4: Casting or Brushing Operation
*Notes: 1. For simple-patterned products, we recommend the pouring method for its ease and simplicity, ensuring smooth flow and efficient de-airing. Low viscosity silicone is ideal for this technique.
2. For intricate patterns, opt for the brushing method to achieve precise pattern replication. High viscosity silicone is essential here to maintain control and accuracy during application.
3. We recommend allowing the silicone mold to cure for an additional 12 hours post-demolding before initiating large-scale production, ensuring optimal durability and performance.

Silicone Rubber for Concrete Stamp Moulding Durable Flexible Liquid RTV2 Silicone:
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.
