Product Description

    Two component RTV Silicone rubbers is a kind of elastomer, somebody also call it silicone elastomer. What OTT provide is RTV2 silicone rubber, it's liquid silicone which will vulcanize in both room temperature or heated temperature with good self-leveling ability. It including part A+ part B with mixing ratio 100:3, 1:1 or 10:1 for your choice.

Features:

1.Almost nil shrinkage

2.Good fluidity, operability and excellent operation

3.Good resistance to weather, temperature, aging, acid

4.Excellent tear strenght, comfortable duplcation times

5.High chemical resistance to aggressive components of some types of resins

6.Food grade silicone(environmental, odorless and nontoxic

7.High resistance to high temperature and aging(resist -60 to 200ºC)

 

Product Parameters

Tin cure silicone
 

Part A: Silicone rubber is a white liquid

Part B: Catalyst is a non-toxic and odorless liquid, with transparent color.

ATT: We can provide fast/medium/slow catalyst for hot, warm or cold season.

Notes: 1.The data are based on the operation under room temperature of 25°C.

2. The data-sheet of viscosity, hardness, working time, curing time can be adjusted according to your requirements.

Instructions

1. Make sure the surface of the original is clean and free of loose material. 

2. Weight 100g Part A base and 3g parts B of Curing Agent in a clean container.

3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.

4. Mix Part A and Part B evenly until the catalyst completely dispersed in the base. 

5. Pour the mixed Part A base silicone and curing agent as soon as possible onto the original

6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.

Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 min under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

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.
