1. Ensure the original's surface is pristine and devoid of any loose particles.
2. Accurately weigh 100 parts of Part A base and 2 parts of CA25 Curing Agent into a clean container.
3. Thoroughly stir Part A base silicone before use to prevent filler separation from extended storage.
4. Blend Part A and Part B evenly until the CA25 is fully integrated into the base.
5. Promptly pour the combination of Part A base silicone and CA-25 curing agent onto the original surface.
6. Allow de-molding after 24 hours to enhance the silicone mold's replicate efficiency.
Note: It is highly advisable to remove entrapped air using a vacuum chamber, allowing the mixture to expand and collapse fully. After an additional 1-2 minutes under vacuum, inspect and use the mix if it is bubble-free. Expect a 3-5 times volume increase upon vacuum de-airing, thus choose a suitably large container.

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.
