EZ-Spray Plastic was specifically formulated to be mixed and sprayed via Smooth-On’s EZ-Spray Jr. spray system. With high impact resistance, EZ-Spray plastic is versatile and can be sprayed over a rubber mold to create “mother molds” or support shells. It can also be sprayed or meter mixed into rubber molds as a fast setting casting resin. Cured plastic is lightweight, tough and durable. EZ-Spray plastic has a fast gel time for vertical surface application.
