Cotol-240™ makes GEAR AID urethane adhesives including Seam Grip®, Aquaseal®, and Freesole®, dry faster and it preps slick surfaces for better bonding. The solvent cleans and prepares the surface, readying it for urethane adhesives. It speeds the tack time to 15 minutes and the full cure time to less than two hours. Cotol-240 is also ideal for removing tar, sap, glue, and other resins from various surfaces including glass, plastic and metal.

Product Application

Shake Cotol-240 for 30 seconds before use to blend the thickening agent and return to it's liquid state. For easiest clean up, wear disposable rubber gloves. Read below for directions on how to use with Seam Grip, Aquaseal and Freesole.


  1. Spot test in an inconspicuous spot for color fastness. Apply a small amount to the damaged area with brush.
  1. Buff thoroughly with a rag until dry, or allow to air dry.
  1. For fabric surfaces, apply adhesive as usual. Smooth surfaces should be roughened with sandpaper, then repeat steps 1 and 2.
  1. If a white film appears after Cotol-240 dries, remove with soap, water and a sponge.


  1. Mix 1 part Cotol-240 to 3-4 parts Seam Grip, Aquaseal, or Freesole using a stick, toothpick, or knife. Mix thoroughly on a non-absorbent surface such as plastic.
  1. Immediately apply the mixture to the damaged area.
  1. Keep repaired area level and cure at least 2 hours before using. Test before use.

STORAGE: Cap tightly. Store in cool, dry place. 

Why is Cotol-240 Cloudy or Hard?

To comply with child safety laws in the State of California, a thickening agent was added to the 1/2 oz. bottle of Cotol-240.  Before using Cotol-240, shake the bottle for at least 30 seconds.  The new formula should not affect bonding.  However, if used as a pre-cleaner, the thick version Cotol-240 will leave a white film. You can remove this by wiping with a soapy sponge. Water alone will not work.
