Provides fast, easy, economical sealing of saw-cut openings that protect traffic loop detector wires.

SEALTIGHT SEALEX Cold-Applied Loop Sealant is an efficient and economical material for traffic loop sealant application requirements.

Technical Description
SEALTIGHT SEALEX Cold-Applied Traffic Loop Sealant is a two-component, pourable sealant. It will not harm the insulation on electrical cables. SEALEX requires no special heating or application equipment. It bonds tenaciously to both Portland Cement and asphaltic concrete pavement. Summer temperatures will not cause SEALEX to flow from cracks or be picked up by vehicular traffic. Its bond and flexibility are retained during cold winter temperatures.

The product mixes quickly and easily. The container can be used for both mixing and pouring. It features a convenient pouring spout for direct application. SEALEX can be opened to traffic soon after application.

Viscosity: Like medium-weight oil.
Work life: Approximately 30 minutes.
Tack-free time: 60 minutes depending upon road surface temperatures and weather conditions.

SEALEX is ideal for sealing saw-cut openings used to hold the sensitized wiring loops that control traffic signals, parking lot gates, ticket dispensers, traffic counters and similar equipment installations.

Application Tools

Electric Drill with Mixing Paddle

Wooden Stir Stick


SURFACE PREPARATION: Openings for loop detector wires to be marked and sawed to width and depth specified by equipment manufacturer. Remove debris, dirt and dust from the openings with clean compressed air. Openings must be dry and free of any moisture.

MIXING: SEALEX has 2 components that are accurately pre-measured for ideal curing. Pour all of Part A Activator into Part B Base Material in the imperial gallon can suitable for mixing. Proper blending can be accomplished with a wooden paddle stirred by hand or with a slow-speed electric drill fitted with a typical commercial mixing paddle. In either case, components must be thoroughly mixed. Blend material from top to bottom as well as in a circular motion. Scrape sides and bottom of the container to assure complete integration of the 2 components.

After thorough mixing, replace lid tightly on container, extend the collapsible pouring spout built into the container lid, then begin pouring. Material will flow and completely encapsulate the cabling. Fill flush and strike off clean. If necessary to open to traffic early, SEALEX may be dusted with talc, dry cement powder, or any suitable dusting agent.

REMOVAL: The cable and sealant may be removed by running a knife along both saw cut interfaces and lifting the loop out in 1 piece.
