Abstract

The subject invention pertains to compositions and methods of coating objects using BOC-butenolide. The invention also relates to compositions and methods for enhancing the performance and longevity of the coated objects with BOC-butenolide, including inhibiting fouling often caused by marine organisms.

Claims (18)

1. A method for enhancing the performance and/or longevity of an object or surface, said method comprising contacting or applying an effective amount of a composition comprising BOC-butenolide according to formula (I) to a surface and/or an object:

2. The method of claim 1 , further comprising releasing the BOC-butenolide from the composition after application to the object and/or surface at a rate of about 140 μg cm −2 day −1 to about 150 μg cm −2 day −1 .

3. The method of claim 1 , wherein the performance and/or longevity is enhanced by one or a combination of the following:

a) inhibiting, limiting, or ceasing corrosion;

b) inhibiting fouling by living organisms or non-living substances;

c) inhibiting abrasion; or

d) cleaning.

4. The method of claim 1 , wherein the composition further comprises a coating component.

5. The method of claim 4 , wherein the coating component is a polymer, binder, pigment, solvent, buffering agent, or any combination thereof.

6. The method of claim 5 , wherein the polymer is a Poly(ε-caprolactone)-based polymer, according to formula (II):

wherein n is about 1 to about 10 and m is about 1 to about 10.

7. The method of claim 1 , wherein the surface and/or object is submerged in water or is a medical device.

8. The method of claim 7 , wherein the submerged surface and/or object is a ship, hull, tubing, pipe, pump, propeller, buoy, or rope.

9. A composition, comprising BOC butanolide according to Formula (I):

and at least one coating component wherein the coating component is a Poly(ε-caprolactone)-based polymer, according to formula (II):

wherein n is about 1 to about 10 and m is about 1 to about 10.

10. The composition of claim 9 , wherein the composition is a paint, stain, adhesive, primer, sealant, finish, varnish, polish, lacquer, anti-fouling substance, and/or anti-abrasive substance.

11. The composition of claim 10 , wherein the BOC-butenolide is at a concentration of about 25 μg/mL and the polymer is at a concentration of about 80% to about 99%.
