Nox-Crete Silcoseal Select (Water-based)

SILCOSEAL SELECT is a new generation cure and tilt-up bondbreaker. In contrast to most conventional cure and bondbreakers, SILCOSEAL SELECT does not contain any wax or hydrocarbon resins and, as a result, does not depend on a physical barrier deposited on top of the casting slab to prevent bonding.

Instead, SILCOSEAL SELECT consists of a special formulation of chemically reactive organic compounds in a predominately water based solvent system which chemically react with calcium hydroxide, a byproduct of the cement hydration reaction, present in the concrete surface pores. The reaction products are amorphous gels which, in conjunction with other combined special organic compounds in SILCOSEAL SELECT, eff ectively seal concrete surface pores.

Moisture entry or exit is restricted, allowing good retention of concrete mixing water to assist in providing proper cement hydration and concrete curing and also minimizes concrete surface cracking and crazing. Properly applied, SILCOSEAL SELECT positively prevents the bonding of tilt wall panels to casting slab fl oor surfaces.

Feature and Benefits

• SILCOSEAL SELECT is more eff ective than all other previous versions of SILCOSEAL.
• Provides improved resistance to the “osmotic eff ect” by restricting the natural tendency for water to migrate from freshly placed panel concrete through the bondbreaker fi lm and into the less moist casting slab. Reducing the “osmotic eff ect” greatly improves panel concrete surface appearance resulting in a smooth, uniform surface profi le, color and appearance.
• Achieves exceptional wall panel surface appearance.
• Leaves no residue or resulting staining on wall panel or casting slab fl oor surfaces when properly applied.
• Achieves a crisp, positive release that minimizes panel surface defects and reduces panel resurfacing/patching costs.
• Does not contain any wax or hydrocarbon resins like many conventional bondbreakers which often leave a diffi cult-to-remove residue on wall panel and casting slab surfaces. When this residue is not properly removed, it often causes fl oor and exterior wall panel paint and coating adhesion problems.
• Meets the moisture retention properties of ASTM C309 when applied to a steel troweled surface prepared in accordance with CEN/TS 14754.
• SILCOSEAL SELECT dries faster than all other previous versions of SILCOSEAL due to a special blend of fast-drying solvents.
