Two-Component Silicones for Moldmaking


Let Eager Polymers' wide selection of two-component silicones be your one-stop source for mold-making. Silicones offer excellent natural release properties for casting and will pick up the finest details. Choosing the correct system will allow for the working and curing times and the flexibility to be tailored to your needs. Eager Polymers has been supplying the molding industry with silicone for over 20 years. Eager Polymers' silicones can be broken down into two categories:
Tin-cure systems: Platinum-cure systems:
