Dacron UV Coated Sailcloth is knife coated with a urethane impregnated with Titanium Dioxide-Plus and white pigment. The UV coating molds to each filament for increased adhesion and a longer lifespan than older coatings that tend to crack and flake. Use as a UV sacrificial cover to add strength and UV protection to your furling sail. This UV Dacron is also perfect for lightweight awnings or in crosscut sails. Coated on both sides.
