Rubber Cement - Formula

Formula

The formula for rubber cement varies according to its targeted application. Those commonly used in office and art applications are usually non-vulcanizing and seldom differ between brands. However, they have been reformulated over time due to concerns over the toxicity of the chemicals involved, especially in regard to its use by children. Consumer-grade products generally no longer contain benzene because of its link to certain cancers. Instead, they tend to be based on less toxic solvents such as n-hexane and n-heptane.

Rubber cement based on n-heptane is very popular and ubiquitous in the United States, but is generally unknown and unavailable as a consumer product in the UK and some parts of Europe. A similar solvent based product called "Cow Gum" was common in the UK, but is no longer in production. Current solvent based options include Marabu-Fixogum and Platignum "Studio Gum" which are marketed in the UK and Europe. A water-based latex adhesive available in the UK is Copydex. Marabu-Fixogum rubber cement and its thinner contain acetone as a solvent.

For tire patching, shoe repair, and other industrial applications, vulcanizing formulas are preferred. These contain chemical additives which enable them to cross-link and harden into a tougher, more resilient form.
