SPRESIN Model-Pro Polyurethane Casting Resin 1 Gal and Cast-a-Mold 25T RTV 1/2 Gal, Silicone Mold Making Rubber, Crafts, Woodworking, Hand Molds Casting & Jewelry Making

Model-Pro is a two-part polyurethane casting resin with a 2.5-minute working time and the impact resistance and strength necessary for practical and artistic applications. It is commonly used to make figurines, models, molds, prototypes, and reproductions for both hobbyists and professionals alike. Model-Pro is versatile and easy to use. This rigid polyurethane casting resin is formulated without any solvents for safer, odorless casting. Model-Pro casting resin uses a simple 1:1 mixing ratio and can be mixed by hand or automated dispensing equipment since it contains no fillers. Room-temperature-vulcanized (RTV) silicone molds play well with polyurethane resin casting, and Model-Pro cures in just 15 minutes, so you can quickly demold and get to the next step of your project. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- Cast-A-Mold 25T is a general-purpose tin cured, room-temperature-vulcanizing (RTV) silicone casting rubber used for creating flexible rubber molds. You can use these liquid silicone mold-making kits for casting polyurethane, epoxy and polyester resins, as well as materials like cement, concrete, wax, soap and plaster. These liquid silicone mold-making supplies are easy to use and de-air, with materials that cure at room temperature on almost any surface. Cast-A-Mold 25T mold-making silicone provides a working time of 1 hour and is ready to demold in less than a day.
