In this tutorial we mold a diecast auto overall body using Gel-25. PlatSil Gel-25 cures to an A25 in about 1 hour so it is excellent for quickly 2 piece molds. Gel-25 is extremely reduced viscosity so it is best for quick molds and does not require degassing for most programs. The last product auto overall body was cast in EZ Flo sixty casting resin with yellow PolyColor included. There are numerous PlatSil Silicones that would operate effectively for this approach: 73-20 (for truly tiny quickly molds), 73-25 (For larger 2 piece molds that require a more time pour time), or 73-15 (for tiny 2 piece molds or lower block molds). All of those choices may possibly be employed with no vacuum degassing. If you are heading to be pressure casting, vacuum degassing is a must! Less than pressure micro bubbles can extend or contract creating surface area imperfections in the last resin cast.
The mold in this online video required about 5 lbs of PlatSil Gel-25. You can uncover Gel-25 in 2lb kits or larger on our webstore: http://www.shop.brickintheyard.com/PlatSil-Gel-25-2lb-Kit-Gel25U2.htm
