HY- E625Addition Molding Silicone rubberDescription:HY-E625# addition molding silicone is generally named two-components silicone rubber, Part A is a flowable liquid, part B is the curing agent. It features an exceptional fluidity and good operability. The mixing ratio is 1:1, mainly be suitable for making molds application.Applications:HY- E625# addition molding silicone could be mainly used for making concrete stones, precision molds, PU molds, for life casting, fabric finishing, shoe soles making， seal for electronic components and solar circuit board, trademark decoration. etc.Technique Data:ModelHY-E625# AppearanceTranslucentMixing Ratio1:1Operating time (Mins 25°C)30 - 50Curing time (Mins 25°C)120 - 240Curing time (Mins 60°C)20 - 30Hardness (A°) 25±2Density ( g/cm 3 )1.08Viscosity (CS) (Part A)30000 ± 5000Viscosity (CS) (Part B)5000 ± 500Viscosity (CS) (After mixed)10000 ± 2000Tensile-strength( kgf /cm2 )50± 5Tear-strength (kgf /cm2 )15 ± 2Elongation-break(%)500 ± 50Retractility(%)≤0.1OPERRATING INSTRUCTION: 1. Clean your products and brush a layer of release agent (detergent or soap water) on the surface of your product.Note: The model should not have been used to make molds for tin cured silicone rubber before. Otherwise, the addition silicone will not get cured. (Use a new model to test it)2. Enclose the product (the original model) with four plastic plates or wooden plates.3. Mixing part A and part B with 1:1 mixing ratio and stir 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)4. Pour the mixture 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 .SHELF LIFE: Twelve (12) months from date of shipment when stored at 24℃ in original unopened packages.PACKAGE: Packed in clean 20kg/pail, 200kg/pail.
