mould making silicone rubber with platinum catalyst for resin jewellry craft
Applications,
HY- E642# addition molding silicone could be mainly used for making concrete stones, precision molds, PU molds, resin molds, gypsum casting, candle molding,for life casting, fabric finishing, seal for electronic components and solar circuit board, trademark decoration. etc.
Description
HY- E642# addition molding silicone is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 1:1,mainly be suitable for making molds application.
Item No | Color | Hardness (A°) | Viscosity (CS) | Tensile-strength( kgf /cm2 ) | Tear-strength (kgf /cm2 ) | Elongation-break(%) | Mixing Ratio of silicone and catalyst | Application(most for resin, gypsum and cement product to make moulds) | |
E635 | Translucent | 35±2 | 8000±2000 | ≥60 | ≥13 | ≥400 | 1:1 | Most suitable for medium sized product | |
E642 | Translucent | 42±2 | 10000±2000 | ≥60 | ≥15 | ≥450 | 1:1 | Most suitable for large sized product |
Addition Molding Silicone for PU molds copied
OPERRATING INSTRUCTION of HY-E642# molding silicone:
1. Stir part A and part B with right mixing ratio (1:1) evenly. And get the mixture for vacuum-pumping. (If there is no vacuumizer, you can just pour the mixture slowly from the corner so that less bubbles caused)
2. Enclose the product (the original model) with four plastic plates or wooden plates.
3. Clean your products and brush a layer of release agent(detergent or soap water) on your product.
4. Pour the mixture with correct mixing ratio into the model frame.
After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold .
The solutions of the sticky of the Liquid silicone mold?
The main reason for this problem is that you do not handle the products or original molds well, then you should deal with the original mold or products carefully before molding. Such as for the products with a complicated
pattern or a unsmoothed surface, you should polish and clean the products after which it will be molded ,then spray the release agent. Normally, the release agent can be Vaseline , detergent. liquid wax Etc. In practical process, you can bush different release agent according to different material.
The second reason is that the operator pour the silicone into the mold when the mixture is mixed evenly, then the finish silicone mold will not cure and dry entirely..
SHELF LIFE:
Twelve (12) months from date of shipment when stored at 24°C in original unopened packages.
