ROCKBOND FORM RELEASE (RB 7.18) is a general purpose chemical release agent. The chemically active ingredient contains fatty acids and these weak acids react slowly with the alkalies in cement to produce water-insoluble soaps. When applied at the recommended dosage, fatty acid based release agents, based upon volatile solvents, leave a dry film on the surface of the concrete, which becomes the release agent.

SPECIAL PROPERTIES

Provides a clean and easy release or “strike” without damage to either the concrete face or form.
Provides protection to timber formwork, impregnating and rendering it waterproof and resistant to rot.
In the case of steel moulds regular use will inhibit rust.
Has no adverse effect upon the form or the concrete surface.

USES

ROCKBOND FORM RELEASE (RB 7.18) is effective on all types of moulds and formwork as well as being suitable as a panel bondbreaker for tilt slab construction. While ROCKBOND FORM RELEASE (RB 7.18) is generally used for tilt slab construction, if preferred ROCKBOND TILT RELEASE (RB 7.21) can be used in this application.
