Ultima SR-40 utilizes a high cuprous oxide load (40%) combined with the power of Irgarol to offer outstanding dual biocide, multi-season control in alltypes of fouling. It employs a unique controlled erosion technology to minimize coating build-up and keep underwater surfaces smooth. Its ablative surface wears away with use providing a continuous supply of fresh biocides while eliminating the need for sanding. Ultima SR-40 contains PTFE for added performance and reduced friction. It can be hauled and re-launchedwithout repainting. Formerly sold as Ultima SR and Horizons Pro, this formula has a proven track record as one of Americas premium ablative bottom paints. Ultima SR-40 is an excellent choice for power or sailboats with fiberglass, wood or steel hulls.Dual biocides with 40% copper for outstanding controlUnique controlled erosion minimizes build up & keeps surface smoothAblative, multi-season technology provides a continuous supply of fresh biocidesContains PTFE for reduced frictionExcellent for fiberglass, wood and steel boatsFormerly known as Ultima SR and Horizons ProVEHICLE TYPE: Synthetic Polymer/RosinCURING MECHANISM: Solvent ReleaseSOLIDS (theoretical): By weight...79 +/- 2%By volume...56 +/- 2%COVERAGE: 450 sq. ft/gal.VOC: 330 g/l max.
