A student uses rubber cement to attach a photograph to a poster board.

Definition

Noun: 1. An adhesive compound: A type of glue consisting of unvulcanized rubber dissolved in a volatile organic solvent, such as benzene or naphtha. It is used for joining materials, especially paper, where a flexible and temporary or repositionable bond is desired.

Usage

Rubber cement is primarily used in arts, crafts, and office settings. Its key characteristic is that it forms a bond that can remain flexible and, before it fully sets, can be repositioned. Excess adhesive can often be rubbed off easily once dry. - Use: Apply a thin layer to one or both surfaces, allow it to become tacky, and then press the surfaces together.

Examples
  • Noun:
    • She used rubber cement to assemble the collage for her art project.
    • For a temporary bond, rubber cement is often preferred over permanent white glue.
    • The solvent in rubber cement evaporates quickly, leaving the rubber behind as the adhesive.
Advanced Usage
  • "Repositionable adhesive": This phrase describes a key property of rubber cement, allowing items to be adjusted after initial placement before the adhesive fully dries.
  • In professional graphic design and paste-up (a pre-digital technique), rubber cement was the standard adhesive for laying out artwork and text.
Variants and Related Words
  • Contact cement: A related but stronger adhesive that also uses rubber in a solvent. It is typically applied to both surfaces, allowed to dry, and then bonded permanently on contact. Unlike standard rubber cement, the bond is immediate and very strong.
  • Adhesive: The general category for substances used for sticking objects together.
Synonyms
  • Flexible glue
  • Paper cement
  • Repositionable adhesive
Notes
  • The solvents traditionally used in rubber cement (e.g., benzene, naphtha) are highly flammable and have significant health hazards. Modern formulations often use heptane or other less toxic solvents.
  • It is distinct from construction or household cements (like PVC cement or super glue) which create rigid, permanent bonds on materials like plastic, metal, or wood.
