ProSIl 1025 RTV Silicone Mold Making Rubber Kit (Gallon)
Brand: ProSil 1025
Color: White A, Blue B.
<b>Prosil 1025</b> mold making rubber is a two-component material, consisting of Part A base silicone and Part B curing agent, cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, PU, GRC, cement, resin, polyester, wax etc. <br><br> <b>APPLICATIONS: </b> Prosil 1025 is suited for reproduction of cement molding, concrete stones, artificial stones,plaster molding, figures, art objects, decoration molding, gypsum products, resin products, etc. <br><ul> <li>Shore A: 20</li> <li>Cure Time: 24 hours</li> <li>Viscosity: 22,000 cps</li> <li>Mix Ratio: 10A:1B</li> <li>Shrinkage:0.3%</li> <li>Specific Gravity: 1.2</li> <li>Tear Strength: 143 pli</li> <li>Elongation: 600%</li> <li>Tensile Strength: 3630 psi</li> </ul> <b>MIXING:</b> Please weight 100 Part A base and 10 parts of 1025 Curing Agent in a clean container. Thoroughly stir Part A base silicone before use, as filler separation may occur upon prolonged storage. Mixing Part A and Part B evenly until the 1025 Curing Agent is completely dispersed in the base. Hand or mechanical mixing can be used, but do not for an extended period of time or allow the temperature to exceed 35C (95F). Mix suitably small quantities to ensure thorough mixing of base and curing agent. It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 minutes under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.<br><br> <b>POURING THE MIXTURE AND CURING: </b> Pour the mixed Part A base silicone and 1025 curing agent as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature. Demold after 24 h
