Condensation cure silicone rubber Description

    DC-C25 liquid tin cure(condensation cure ) rubber is a kind of two part silicone rubber with mixing ratio of 100:2~10:1

    and the normal curing remperture is room temperture, so it is also call room temperture cure silicne rubber or RTV(Room temperature vulcanized silica gel)

   

 

Characteristics of condensation cure silicone rubber 

*excellent fluidity and good operability, easy to demold

* hihg tensile and tear strength  

* bubble releasing easily

*Non-deformation

*Low shrinkage

*Aging resistance ,high temperature resistance (220℃)

*Environmentally, food-grade

 

Application of condesation cure silicone rubber

    condesation cure silicone rubber is mainly used for making molds . For Example, making mold for  concrete stone,GRC,polyurethane products ; wax, candle decoration ; rapid prototyping and tyre molds; ,candy and similar products.

Operation instructions

Step 1: prepare the original molds 

Prepare an perfect original mold and clean it totally before operation .

*Notes:Make sure your original molds(Model) and operation tool cleaned up totally to avoid uncure problem .

 

Step 2: Take 100 G part A and 2 G part B(catelyst ) (Or 100 G part A and 10 G part B) and mix them evenly.

 

Step 3: Vacuum pumping

Without exception, this step takes less than 8 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

 

Step 4: Pouring casting or Brush operation

*Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .

        2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .  

        3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .
