Abstract

Chemical compositions are disclosed. One exemplary composition, among others, includes: a basic component, an acidic component, at least one acrylate component, oxidizing agent, reducing agent, and a binder. The binder includes a viscosity modifier and a surface tension modifier. The binder is capable of stimulating a reaction between the basic component and the acidic component. A portion of the binder is capable of undergoing a polymerization reaction between at least one acrylate component, the oxidizing agent, and the reducing agent. The polymerization reaction being initiated by the redox reaction between the oxidizing agent and the reducing agent.
