Food Grade Silicone RTV For Sugar Mold Making rtv silicone food grade are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1.

Food Grade Silicone RTV For Sugar Mold Making Appilications |
Especially suitable for the molding of sugar,chocolate,cakes ect. Food Grade Silicone RTV For Sugar Mold Making Feactures |
/Good fluidity and good operability and good for pouring method. /Excellent mechanical properties, in particular tear strength and tensile strength. /Excellent flexibility and it is easy to demould. /High temperature resistance, high duplication times and repeated use. /There are a range of catalysts/curing agent/hardener allows the Liquid rtv silicone rubber to fulfill requirements for various applications and various requirements on the operation time and curing time. How to use Food Grade Silicone RTV For Sugar Mold Making |
1.The cast pouring, for example: Prepare a frame, fix the prototype for copy into the frame, (if the prototype’s material is glass or ceramic, the release agent is necessary to prevent sticking. 2. Take 1 part A and 1 part B,mix themevenly. 3.Vacuum defoaming in 1~3 min,inject the rubber into the type box, then vacuum defoaming again, curing 24 hours in nature room temperature, use it after demold. 4. Demold after 3 hours’ room temperature curing, and then use it after 24 hours’ keep mold under the same condition.
How to make a perfect silicone molds with Food Grade Silicone RTV For Sugar Mold Making |
Firstly,the silicone rubber and catalyst must be mix evenly,mixing for 5-6 minutes,if you do not mix evenly,it will cause one part is dry but other part is wet. Secondly,if you have a vacuumed machine,that's will be perfect, vacuuming mixed silicone for 5-6 minutes,there will not have bubble. Thirdly,the silicone mould need 24 hours to complete dry,so when you finished the silicone mould,please after 24 hours later bring into production. I believe that the silicone mould will be perfect if you pay attention to these points.
