carbonblack composites Mold Release Wax + PVA Combo (Large)

15 sample prepared of composite.. 12 from these agent and 3 from simple silicone grees...silicon sample have nice superb finish and good quality but this aget destoryed my 12 composit sample.. Wax Problems.. 1- wax is thik white which will be good before casting but after casting all the wax will create a unremovable thik layer on acrylic sheet or mold that mean you can not use this mold again... 2- surface is of composite will be very poor.. but composite can be remover from mold very easily.. PVA OR BLUE LIQUID AGENT Problems 1- bad bad bad bad bad and very bad product don't buy this blue liquid 2- it is not a liquid so when you apply this on wax coated mold it will creat thousands of boubles on it these bubles will not ge whatever you do.. thus because of these bubbles after the casting, surfaces of composite will also have thousand of bubles over there.. 3- very very poor surface finshi of the composite sample after application of this agent.. Never use these bubbles or bubbling liquid it will destroy your casting ... I realised it after 12 sample.. then i switch to silicon grease... Overalll its not a good product for any casting of composite... Specially that blue liquid agent... Don't buy.. 3-
