Rubber Cement, a long-time staple of the graphic arts studio, can be used and stored safely if instructions are followed carefully, but artists should be concerned with both flamability and toxicity. Dick Blick is happy to identify and supply alternatives to rubber cement for many applications.
Flammable materials (like most rubber cements and their thinners) cannot be shipped by air. Federal Express charges an additional fee for shipping flammable materials in one-gallon and larger containers. If you choose Federal Express as your shipper, this charge will be added to your invoice.
