Forms a smooth, glossy surface that will not shrink or pull away from corners or curved surfaces Particularly recommended as a parting agent for separation between polyester or epoxy resins and various mold surfaces, but may be used with most thermoset resins TIPS: PVA can be brushed on. Generally, apply in three layers: the first, a thin mist, allowing 10-15 minutes to dry completely - then apply two heavier flow coats, allowing each to dry completely (15-20 minutes each) May be applied over polyester repairs, or gel coat, as a surface layer for airless tack-free cure Mold Release Wax is a special blend of imported waxes specifically formulated to provide the maximum number of releases per application. For fiberglass applications. Especially useful on tooling and new molds. This wax is a non-silicone white wax specially formulated to produce a tough, durable, high-gloss surface. When used with our PVA mold release agent, Mold release wax delivers excellent release characteristics. Special preparation is required when using on a new mold: Apply four total coats before initial use. Apply two coats of wax and buff off excess. Allow one hour for solvents to evaporate, producing a tougher wax barrier. Apply final two coats. Then apply 2 coats of PVA for perfect release Review: Waste of money and poor quality - 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- ## Features - conatins 800g mold release wax + 1000g PVA release agent - PVA Water soluble - Can be brushed on - Create a smooth, glossy surface that won’t shrink or pull away - Produces a tough, high-gloss surface with excellent release characteristics ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08K7PHM8K | | Best Sellers Rank | #33,533 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #498 in Universal Adhesives | | Capacity | 1 count (Pack of 1) | | Color | Blue | | Country of Origin | India | | Customer Reviews | 4.0 4.0 out of 5 stars (7) | | Date First Available | 26 September 2020 | | Item Part Number | CBC279 | | Item Weight | 500 g | | Net Quantity | 1.0 Count | | Primary material | Plastic | | Shipping Weight | 500 Grams | ## Product Details - **Brand:** carbonblack composites - **Item Form:** Paste, Liquid - **Net Quantity:** 1.0 Count - **Number of Items:** 1 - **Recommended Uses For Product:** Smooth, Gloss Enhancement - **Specific Uses For Product:** Smooth ## Images ![carbonblack composites Mold Release Wax + PVA Combo (Large) - Image 1](https://m.media-amazon.com/images/I/416KSq8sg2L.jpg) ![carbonblack composites Mold Release Wax + PVA Combo (Large) - Image 2](https://m.media-amazon.com/images/I/41zSHllXhbL.jpg) ![carbonblack composites Mold Release Wax + PVA Combo (Large) - Image 3](https://m.media-amazon.com/images/I/61WMwz9og2L.jpg) ![carbonblack composites Mold Release Wax + PVA Combo (Large) - Image 4](https://m.media-amazon.com/images/I/81car9izzvL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐ Waste of money and poor quality *by P***R on 31 May 2022* 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..
