Abstract
A method for stabilizing triphenylboron-pyridine (TPBP) in a solvent-based anti-fouling coating, such as a marine anti-fouling coating, by adding to the coating about 0.04 to about 0.40% wt., based on the total amount of the triphenylboron-pyridine, of 2,2,6,6-tetramethylpiperidinyl-1-oxy-radical (“TEMPO”). Also disclosed is a solvent-based anti-fouling coating, such as a marine anti-fouling coating, composition containing TPBP and TEMPO.
Claims22
A method for the stabilization of triphenylboron-pyridine in a solvent-based anti-fouling coating which comprises adding to the coating from about 0.04 weight percent to about 0.40% wt., based on the total amount of the triphenylboron-pyridine, of a sterically hindered nitroxyl radical of formula 1
- wherein each R is a methyl group.
A solvent-based anti-fouling coating composition comprising triphenylboron-pyridine and about 0.04 wt % percent to about 0.40% wt., based on the total amount of the triphenylboron-pyridine, of a sterically hindered nitroxyl radical of formula 1
- wherein each R is a methyl group.
