OPTICALLY CLEAR BIOFOULING RESISTANT COMPOSITIONS AND METHODS FOR MARINE INSTRUMENTS

摘要

An optically clear biofouling resistant coating compositions specially formulated for very high light transmission and more particularly coating compositions which can be applied to marine instruments and sensors. The compositions provide a biofouling resistant coating on the surface of the marine instruments and sensors which prevents underwater organisms from adhering and growing on the surfaces of the structures over a long period of time.

主权项

1. A biofouling-resistant coating on a substrate used for submerged marine applications, the coating comprising:
a tie coat on the substrate used for submerged marine applications; and a biofouling-resistant composition comprising a curably reactive organopolysiloxane having at least one terminal reactive functional group, at least one silicon bonded organic group, and an organopolysiloxane cross linking agent; wherein said terminal reactive group is a hydroxyl group, an alkoxy group, an aryloxy group, an amino group, an amido group, a halogen, or a vinyl group; and said silicon bonded organic group is a methyl group, an ethyl group, a vinyl group, a haloalkyl group, or a phenyl group; wherein the biofouling-resistant coating has greater than 50% light transmission of wavelengths between 400 nm and 800 nm, and wherein the coating has a refractive index of 1.30 to 1.56.
