Additional Details

Silcoseal Classic is a solvent-based tilt-up cure and bondbreakerIts traditional, solvent-based formulation allows tilt-up panels to separate easily and completely without the use of pry bars or wedges commonly used with membrane-forming bondbreakers. The solvent-based formula also dries faster than water-based formulations and high humidity does not affect it.

Instead of being reliant on wax or hydrocarbon resins like other bondbreakers, Silcoseal Classic has an organic compounds formulation. These compounds react chemically with excess limes present in the concrete surface to form metallic soaps. Apply the product properly and the soaps eliminate wall panel sticking. The absence of wax or hydrocarbon resins means less Silcoseal Classic is needed per project, reducing application time and cost while ensuring exceptional results.

Silcoseal Classic also functions as a high quality cure. Independent tests have shown Silcoseal Classic meets the moisture retention properties of ASTM C309 when applied to a steel troweled surface prepared in accordance with ASTM C156 and CEN/TS 14754.
