Sherwin Williams Envoy TF500 - Formerly Leighs is a tin free ablative antifoulding based on a high performance polymeric resin system for the protection.
Sherwin Williams Envoy TF500 is formulated to provide protection against a wide range of grass and shell fouling where the use of tin-based biocides is precluded. Specifications utilising this product may be varied to provide the most cost effective system to meet operating conditions and service requirements. Compatible with an extensive range of existing bottom systems.
Use Sherwin Williams M535 Vinyl Primer Tiecoat as primer. Ensure surfaces to be coated are clean, dry and free from all surface contamination. Previous antifouling surfaces should be thoroughly high pressure washed and allowed to dry out. Damaged coatings should be re-prepared by spot blasting or power cleaning, and touched-up with anticorrosive primer before antifouling. Where conversion of a bottom from a high performance system to ablative is required it may be necessary to apply an overall coat of compatible sealer. An addition of 5% Cleanser Thinner No.5 is necessary, before brush application can commence, even then it is only suitable for application to small areas. Recommended application methods are via airless spray, roller or for small areas and touch up via brush. Indefinitely self overcoatable. Recommended cleanser thinner No5 for brush and roller application, or Thinner No9 for spray application.
