Low linear shrinkageApplications of RTV2 silicone for architectural restoration mouldingRTV-2 Silicone are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.Physical properties of RTV-2 silicone good for pouring or brushingItem No.: RTV2028Color: WhiteViscosity: 32000 cpsHardness: 28 shore ATensile strength: 4.2 MpaTear strength: 31 N/mmElongation: 510 PercentPot life: 30-40 minsMix ratio: 2 PercentCuring time: 4-6 hoursHow to make the silicone mold?1. PreparingThe surface of the original objects should be clean and free of loose material. If your products have thin flower patterns, and especially have porous subst`rates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.2. MixingPlease weigh Part A silicone base and part B CA30 Curing Agent with ratio of 100: 2 into a clean container. Stir Part A base silicone thoroughly before use, then Mix Part A and Part B evenly until the curing agent completely dispersed in the silicone base. Manual or mechanical mixture can be used, but do not last much time or allow the temperature to exceed 35& 176 C (95& 176 F). Its suitable to mix small quantities to ensure thorough mixture of silicone base and curing agent.Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mixture to completely expand and then collapse. After a further 1 to 2 minutes under vacuum, the mixture 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.3. Pouring the mixture and curing Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original object, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature), we advice you de-mould after 24 hours, it is will improve the replicate times of silicone mold.Storage When the silicone rubber is stored at or below 30 centidegree` in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.NoteMC Silicone RTV-2 mold making rubber is an industrial product and must not be used in food molding, dental human skin molding applications.Package of RTV-2 molding silicone rubberPart A base silicone: 20kg/drum, 25kg/drum or 200kg/drumPart B CA30 Curing Agent: 800g/bottle, 1kg/bottle and 10kg/bottle
