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.

Noun

1. an adhesive made by dissolving unvulcanized rubber in a solvent like benzene or naphtha
