Product Description

Product Description

    RTV-2 Mold Liquid Silicone Rubber Candle molds is a two-part-kind liquid silicone, which belongs to food-grade silicone, can be cured at room temperature, and mainly used for mold making of food-grade molds, jewelry casting, tire molding, rapid prototyping, vacuum foaming, etc. It also suits any condensation silicone's application for molding.
    With appropriate hardness, good tensile and tear strength, and excellent resistance to deformation, finished silicone molds have not only a durable life but also good performance.

How to Use

As addition/platinum cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem, so kindly follow the tips below:
* Do not mix with liquid condensation/tin cure silicone rubber or even the tool which used for condensation/tin cure silicone
* Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As, Hg, Ph
* Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem

1. Stir part A (100g) and part B (100g) with 1:1 mixing ratio evenly. Then get the mixture for vacuum-pumping.

(If there is no vacuum machine, you can just pour the mixture slowly from the corner so that less bubbles caused)

2. Enclose the products (the original model) with four plastic plates or wooden plates.

3. Clean your products and brush a layer of release agent (detergent or soap water) on your products.

4. Pour the mixed silicone into the model frame.

5. After about 3 to 5 hours, when the silicone is cured, remove the original model, and then you get a finished addition cured silicone mold.

FAQ

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.
