EXPERIMENTAL FORMULATION OF ANTI FOULING PAINT WITH TRIBUTYL TIN OXIDE ASTOXIC PIGMENT

Abstract

Results of the experimental formulation of ;J.n antifouling paim
incorporating TBTO as toxic pigment are presented in this paper.
Of the various resins tested, namely, phenolic, cashew nut shell liquid
(CNSL), epoxy, li11seed oil with rosin and limed rosin, the paint
compositiOn with limed rosin gave the critical leaching rate of TBTO·
Acid alkali test showed dissolution of matrix and visible migration
of toxin to the surface. Accelerated corrosion tests had not recorded
any signs of corrosion in panels painted with or without barier
coat. Raft exposure studies indicated that the new formulation could
resist fouling accumulation on painted panels for 9 months.
