condensation curing silicone rubber for mold making

1.Application of 2 part condensation cure molding silicone rubber: 

2 part condensation cure molding silicone rubber mainly used for shoe molds, sand casting, sole sampling, plaster models, simple products, products with non-complex patterns, as well as product models with stable size and non-deformation.

2. Features of 2 part condensation cure molding silicone rubber:

2 part condensation cure molding silicone rubber, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration. 

3. Operation instruction of condensation cure molding silicone rubber:

condensation cure molding silicone rubber is composed of two components.Component A is white flowing liquid while component B is the curing agent.

Steps:

a.take silicone rubber of 100g and add 2% curing agent for  mixing evenly.

b. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles.

c.After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame

Note: 2 partcondensation cure molding silicone rubber is used for pouring or brushing technique. That is to say,

firstly fix the product or sole model to be duplicated onto a plane plate,

then enclose the plane frame with wooden plates to prevent the leakage of the silicon ,

thirdly mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model,

at last  brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.

 FAQ of 2 part condensation cure molding silicone rubber 

 1.Why is the appearance of the finished mold striate and unsmooth?

t is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should polish the product, spray the Brushing RTV-2 silicone rubber mold spray evenly on the product. In this case, the problem can be avoided.
