Application

DC-A15 silicone Rubber is mainly used for making molds of concrete stone,GRC,polyurethane products ; wax, candle decoration; rapid prototyping and tire molds; chocolate, candy and similar products molding. 

Description

DC-A15 is a kind of two part silicone rubber in addition cure or platinum cure type with mixing ratio of 1:1 or *0:1.It can cure at room temperature as well as under heat. Its a kind of food grade silicone which has got the United States FDA certification. And mainly used for mold making.

 Characteristics

An exceptional fluidity and good operability, easy todemold

Aging resistance, high temperature resistance 

Environmentally, food-grade, FDA Certification.

Good tensile and tear strength

Outstanding bubble releasing

Very Low shrinkage

Non-deformation

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 and operation tool were cleaned up totally to avoid uncured problem .

 Step 2

   1.Weigh the two part exactly by electronic weight. If any part not in exactly weight, it may cause changing of hardness, or even cause uncured problem.

 2.Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. Whats more, the finished molds will meet a short life. All of these will cause a waste of silicone rubber.

 

Step 3: Vacuum pumping

Without exception, this step takes less than *0 minutes. Otherwise, it will causecross 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 low 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 wont be easy to flow away and easy to brush .  

        3.We suggest to set the silicone mold for another *2 hours after demould before you put it into a large production .
