Polyurethane Molding Silicone Rubber

POLYURETHANE MOLDING SILICONE DESRIPTION
        Polyurethane molding silicone is a kinds of Two-parts silicone, part A is flowable liquid silicon, part B is curing agent/ catalyst ,which gets cured at room temperature 25℃ within 3-6 hours or heating curing .This product is perfect for mold making,such as the polyurethane statuary, plastic crafts, buddha statue crafts,ceramic statues ,etc.


POLYURETHANE MOLDING SILICONE APPLICTION
        RTV-2 mould making silicone rubber provided by HONG YE JIE is quite flexible, specially suitable for the products which are with fine details and patterns, so it can replicate the statuary perfectly due to its high tear and tensile strength. That means, it's suitable for polyurethane statuary, polyurethane arts, poly crafts, candle, soap arts,plaster and gypsum moldings ,ornamental plaster,etc.


POLYURETHANE MOLDING SILICONE FEATURES
1. Excellent tear and tensile strength.
2. Suitable for statuary molding with complicated texture and detailed pattern on the surface of product.
3. High temperature resistance, high duplication times and repeated use.
4. Excellent flexibility, very flexible to demould.
5. Suitable for pouring methods of operation for middle size molds making.
6. An exceptional fluidity with low viscosity and easy operation.



POLYURETHANE MOLDING SILICONE OPERATION
1. Prepare the original mold：Weight part A & part B according to the mix ratio recommended(100:2 to100:5),

2. Mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and bring problems in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.

3. Vacuum pumping:Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

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 .

5. Demoulding:After 3-5 hours later, can demould the silicone mold, It’s will be better for mold to demould after 24 hours Note: We suggest to set the silicone mold for another 24 hours after demould before put into large production .


POLYURETHANE MOLDING SILICONE NOTE
1.The curing rate of this product is closely relevant to the temperature. The higher thetemperature is, the greater the humidity is and the curing speed becomes faster.

2.Users can choose the curing agent according to the weather condition, and adjust the amount of the curing agent in order to reach the appropriated curing rate.
