Liquids, Solvents, and Adhesive Agents use in Repair
COATINGS
Techthane (Oil based): 2-part urethane coating (plus pigment)
Use: High damage areas or abrasion wear areas. Builds extra urethane thickness to withstand heavy usage. Also to
increase UV stability of fabric. (Not intended to repair over-damaged nylon weave!)
Working life: Approx. 2 hours when catalyzed.
Shelf life: 3 months when stored in airtight containers.
Wing PN#A3511 - Techthane Coating Kit - 16oz
Goop (Oil-based): Melted Polyurethane in a solution of THF (tetrahydrafuran)
Use: To fill small scratches and repair minor cosmetic issues. Not used to fix damaged nylon.
Shelf life: 5-6 months when stored in an airtight container.
Wing PN#A3533 - Goop - 1oz
Recommended Adhesives Used In Polyurethane Repair
Clifton 2-part adhesive (Water based):
Use: Securing Polyurethane to Polyurethane
Shelf life: 5-6 months if stored unmixed in airtight containers.
Working life: Once catalyzed, 2 days (depending on airflow, and amount of adhesive mixed). The greater the
quantity, the longer the working life.
Wing PN#A3530001 - Adhesive - 8oz (Part1) / Wing PN#A3530002 - 1oz Catalyst (Part2)
Clifton 1-part adhesive (Water based):
Use: Securing Polyurethane to Polyurethane.
Shelf life: 5-6 months when stored in airtight container.
Working life: 2 days (depending on airflow and amount of adhesive mixed. The greater the quantity the longer the
working life.
Wing PN#1800035 - Adhesive - 4oz
“Flashing-Off” or “Drying to the Touch”
MEK (Methyl ethyl ketone) and acetone are chemicals that serve to clean, soften, and open the pores of the Polyurethane -
a necessary process for any successful repair. In the following fabric repair sequences, reference is made to MEK “flashing-
off” or “drying to the touch” before applying Polyurethane coatings. Both are terms for evaporation. In other references,
directions are to immediately apply adhesives BEFORE the MEK flashes or dries to the touch. The reasons for the different
procedures are that Polyurethane coatings are oil-based, while MEK and the Clifton adhesives are water-based. When
applying an oil-based coating on a water-based solvent it is necessary to let the solvent evaporate, or flash-off before
application or the Polyurethane coating won’t set properly. On the other hand, MEK and the Clifton adhesives are
compatible. The MEK helps to create a better bond wet than it would after evaporation, or flashing.
CAUTION: The repair environment and materials will have a direct effect on the integrity of the repair. For best
results follow these instructions as closely as possible.
