Two-component RTV Moldmaking silicone rubber

Two-component RTV silicone rubber compounds for moldmaking are suitable for mold masters for molding with polyester resin, urethane foam, plaster, and low-melt-point metal alloys. These RTV rubber materials allow accurate reproduction of the shape of the original model. They are easy to use, so it is used widely in industrial applications, as well as by hobbyists looking to create the funny and perfect replica.     In the following this techique bulletin is going to talk about some features of this kind of molding silicone rubber. 1. Workability The base silicones and curing agent are mixed and then poured into the mold to create a silicone rubber mould quickly. Workable time and cure time can be adjusted according to customers’ needs. 2. Favorable mold-releasability The cured rubber can releases easily from the original model. 3. Dimensional stability These rubbers offer very good dimensional stability, with little shrinkage. 4. Good flowability They have excellent flowability so that the original form is reproduced easily and accurately. This includes even intricate shapes and details, such as fingerprints. 5. Good heat and chemical resistance These rubbers have outstanding resistance to heat and lots of chemicals. 6. Deep-section curability Moldmaking RTV silicone rubber compound cures uniformly regardless of its thickness. 7. Non-exothermic No heat is generated during curing process, meaning no adverse effects to the original model. We can supply good-quality silicone, which can be handled by brush molding or pourable molding. There are easy-to-use platinum-cure silicone rubbers which self-thicken for making brush-on molds of almost any original model. Mixed 1A:1B by volume, it can be applied with a brush to vertical surfaces without sagging and will cure with negligible shrinkage. 3 to 4 layers of silicones are all that is necessary to make a very durable production mold for casting wax, concrete or resins.For the platinum silicone, it will last for many years in your mold library.   If some information has interested you, or you wanna get more details of our RTV2 silicone, then you can enter our cellphone entrance: http://m.szrl.net or our computer entrance: http://www.szrl.net.
