Sancon 200

Sancon 200 is a pneumatically placed urethane mortar, which eliminates the need for mortar repair prior to lining installation in concrete sewer structures, designed and applied by Sancon Engineering.

Product Description

Sancon 200 is 3/8" thick urethane mortar used to both protect and structurally rebuild a manhole, wet well, or tank structure.

Sancon 200 is a specially formulated 100% solids, aromatic, MDI (recognized for its superior hydrolytic stability) elastomeric polyurethane coating/lining system for water and wastewater applications. Fluid applied via airless proportioning equipment, Sancon 200 provides a seamless monolithic pinhole free lining for protection of all types of concrete and steel.

Recommended Uses

Sancon 200 is designed for use in gaseous or liquid phase exposures, found in water and wastewater vessels of all types, both steel and concrete.

Sancon 200 is suitable for the protection of concrete or steel in clarifiers, digesters, sedimentation basins, chlorine contact or aeration basins, sewer manholes, pipes or penstocks.

Characteristics

Sancon 200 is self-priming on concrete or steel surfaces, which are clean, dry and properly etched. Adhesion to concrete exceeds the cohesive strength of concrete and shows excellent adhesion to abrasive blasted steel by industry standards.

Surface Preparation

Concrete - No surface preparation is required on clean concrete surfaces free from curing compounds, oils, existing coatings or other foreign materials. Grit blasting is required where the coating is subject to immersion service.

Deteriorated concrete surfaces must be cleaned by high-pressure water to sound concrete. The surface must be free of oil, grease, and soft concrete or existing coatings.

Steel - Steel surfaces require grit blast to near white metal. (SSPC SP-10) Primer or coating must be applied to a dust free surface prior to surface rust appearing.

Application

The lining is applied to a thickness of 375 mils (3/8 inch) in one continuous coat. Without seams, free from any holes or defects. The cured liner, which hardens in minutes, is spark tested to insure coating integrity.
