Abstract
A UV-cured exothermic self-adhesive repair sheet having two components that may be combined in equal sizes. The first component comprises Polyester Resin (25-40%), Glass Fiber (15-25%), Styrene Monomer (<20%) and Inorganic Filler (25-40%). The second component comprises Acrylic Adhesive (75-95%) and Non-Woven Fabric (5-25%).
Claims11
A UV-cured exothermic self-adhesive repair sheet comprising:
- a first component comprising:
- 25-40% polyester resin;
- 15-25% glass fiber;
- styrene monomer, wherein said styrene monomer is less than 20% of the first component;
- and
- 25-40% inorganic filler;
- and
- a second component comprising:
- 75-95% acrylic adhesive;
- and
- 5-25% non-woven fabric;
- wherein the first and second components are combined in equal sizes.
A UV-cured exothermic self-adhesive repair sheet comprising a polyester resin layer and an acrylic adhesive layer, wherein said polyester resin layer has a composition that produces heat of 140° F.-200° F. for at least one minute when said polyester resin layer is cured.
A method for repairing a surface with a UV-cured exothermic self-adhesive repair sheet comprising:
- cleaning and drying the surface to be repaired;
- cleaning the surface to be repaired with acetone;
- removing a UV cured self-adhesive repair sheet from a sealed pouch, wherein said UV cured self-adhesive repair sheet comprises:
- a first component comprising:
- 25-40% polyester resin;
- 15-25% glass fiber;
- styrene monomer, wherein said styrene monomer is less than 20% of the first component;
- and
- 25-40% inorganic filler;
- and
- a second component comprising:
- 75-95% acrylic adhesive;
- and
- 5-25% non-woven fabric;
- wherein the first and second components are combined in equal sizes;
- cutting said UV-cured exothermic self-adhesive repair sheet to a size corresponding to said surface to be repaired;
- peeling off the backing of the UV-cured exothermic self-adhesive repair sheet to reveal the resin;
- pressing the resin side of the UV-cured exothermic self-adhesive repair sheet to the surface to be repaired to adhere the repair sheet to the surface;
- pressing firmly around the edges of the UV-cured exothermic self-adhesive repair sheet to create an airtight and watertight seal between the surface to be repaired and the UV-cured exothermic self-adhesive repair sheet;
- and
- applying UV light to the UV-cured exothermic self-adhesive repair sheet for a sufficient period of time to cure the UV-cured exothermic self-adhesive repair sheet.
