Secondary Containment Systems

Containment systems serve as a backup when the primary system fails. Degraded coatings compromise the system’s ability to perform when needed. The corrosion often remains undetected until the system fails.

Intellathane Systems For Secondary Containment

Intellathane SL-50 is a pure polyurea formulated with a slower reaction time for enhanced sprayability and self-leveling — ideal for large horizontal surfaces and detail work where workability and wire-trimming matter.
See technical data

Intellathane 7347 is a 100% solids, high-performance plural component spray-in-place polyurea protective coating designed to self-level upon application.
See technical data

Intellathane 550 is a two-component, 100% solids polyurea spray elastomer with fast reactivity and designed for use in harsh environments where high temperature, chemical, and/or abrasion resistance is needed.
See technical data

Intellathane 7100 is a two-component, 100% solids, plural component, spray-applied pure polyurea elastomer with instantaneous reactivity designed for use in harsh environments where high-temperature, chemical, and/or abrasion resistance is critical.

Why Secondary Containment Systems Fail

Containment structures generally remain dry most of the time. The coating is only tested when something goes wrong, which is why deterioration often goes unnoticed until an inspection or an incident.

Concrete floors and dikes
Sumps and collection points
Tank pads and ring walls
Loading and transfer areas
Earthen and geotextile-lined containment

Secondary Containment Failure Points

Chemical exposure
Cracking and movement
UV and weathering
Substrate deterioration

What Protection Entails

Secondary containment requires protection that resists the chemicals being contained, accommodates substrate movement, creates a continuous barrier, and withstands environmental exposure.

Chemical Compatibility

Intellathane systems are tested and rated for continuous immersion, temporary immersion, or incidental contact based on chemical type and concentration, allowing the system to be matched to the specific containment environment.

Crack Bridging

Elastomeric Intellathane systems accommodate substrate movement rather than cracking or fracturing, helping maintain a continuous protective barrier.

Seamless Application

Spray application creates a seamless, monolithic membrane across floors, curbing, and transitions, eliminating joints where liquids can penetrate.

UV Exposure

Aromatic systems may discolor with UV exposure without affecting performance. Where color retention is important, UV-resistant Intellathane options are available.

Containment by Industry

Oil & Gas Containment
Tank farms, terminals, loading racks, and process areas require protection against hydrocarbon exposure and outdoor conditions. Intellathane can be applied to concrete containment structures or geotextile-supported systems where no concrete structure exists.

Chemical Processing & Bulk Liquid Storage
Process areas, chemical storage, and bulk liquid terminals require containment for acids, caustics, and other process chemicals. Intellathane systems can be matched to the specific chemical exposure.

Facility Containment
Chemical storage rooms, battery charging areas, equipment pads, maintenance shops, and mechanical rooms need containment that withstands spills and daily use. Fast-curing Intellathane systems combine containment with resistance to traffic, cleaning, and equipment loads.

What Delayed Action Costs

Containment failures can lead to environmental incidents, cleanup costs, reporting obligations, and regulatory compliance activity. Once a coating fails, chemicals and moisture can also reach the underlying substrate, accelerating deterioration and turning a routine recoating project into a more extensive and costly repair.
