BOTE-COTE  EPOXY

 Revised 23/1/08

BOTE-COTE is an epoxy chemical composition particularly for application in marine and other timber construction.  It is especially designed for a unique concept – surface penetration and saturation of a substrate to create a strong impermeable layer fully sealed against water, dirt, and chemical ingress.  It has been developed over many years of testing, in real boats, under real sea-going conditions. 

The technology of wood-epoxy composites has been developed to the point where timber is employed as a fibrous structure in combination with a properly formulated epoxy resin such as BOTE-COTE to form a composite engineering material.  Application of BOTE-COTE to all surfaces on a boat produces an epoxy-wood sandwich, sealing the moisture content of the wood at the level it was at the time of construction – usually around 12% in a normal dry environment.  This epoxy coated surface is nearly impermeable to water vapour, remains tough and elastic, and has superior bonding capabilities.  In addition, BOTE-COTE functions as a fully compatible fibreglass or other fabric laminating resin, as a structural adhesive, and as a fairing compound, in combination with appropriate fortifying and filling compounds. 

Such an engineering material is strong and stable, and most importantly no longer suffers deterioration due to rot.  Rot is caused by fungous organisms feeding on the wood in the presence of water and oxygen.  Sealing the surface with impervious BOTE-COTE prevents entry of these components necessary for rot to develop. 

BOTE-COTE contains no volatile solvents or harmful chemicals, and is one of the safest epoxies on the market.  There is no loss of material nor pin holes resulting from evaporation, and no solvent vapours.  BOTE-COTE is easily applied by paint roller or brush to any properly prepared surface. 

As a two component material, the BOTE-COTE epoxy system consists of a resin and a reactive hardener.  Several hardeners are available to provide a range of reactivities to suit it for different climatic conditions.  Properly formulated fillers for making glues or fairing compounds are an integral part of the system.  BOTE-COTE is also available as a pre-thickened two part glue, and as a higher strength resin designed for lamination with advanced fibre reinforcements such as carbon fibre.
