Marine Self Polishing Co-Polymer Anti-Fouling

Product Description

It has been observed that buildup of marine growth along the underside of vessel hulls has caused many problems.

Some of the problems are as follows

  • The operators face a lot of downtime when these build up of marine growth has to be cleared.
  • Ship and boat drag force increased so that high consumption of fuels.

Flosil-BET Coatings has developed an environment friendly Anti fouling coating system that is acrylate self polishing.

Aqua SPC a one component acrylic, hydrolysing antifouling coating based on ion exchange technology. It provides very good fouling protection and improved hull performance. This is achieved through self polishing characteristics reducing hull deterioration, friction and speed loss. To be used as finish coat in immersed environments only.

  • Anti fouling Silyl acrylate based controlled depletion.
  • Excellent adhesion, durability and abrasion resistance.
  • Marine growth reduction on stationary vessels
  • Easily Repairable giving room for isolated repairs
  • Usable on steel, fiberglass and wooden surfaces
  • Can be easily cleaned /brushed off, even underwater

Systems and Compatibility

Following primers are compatible with the system:

Aqua Sealer, Aqua ST, Aqua ST-03, Aqua Mastic

Following products are compatible with the system as a mandatory Tie Coat:

Hull Koat, Hull Jet

  • Hull of Boats and Vessel
  • Power Stations Intake Areas.
  • Fast Boats and Yacht – Rudders and Keels.
  • Sea Chest

  • Chain Locker
  • Jetties
Air Temperature 5-50° C
Substrate Temperature 5-60° C
Relative Humidity 50% minimum, 85% maximum
Surface temperature shall always be at least 3°C above Dew Point. Do not expose the coated articles where there are chances of condensation on the surface.

Surface Preparation

All surfaces to be coated shall be dry and free from oil, grease, dust, dirt and any foreign matter that can adversely affect adhesion of coating. Solvent cleaning as per SSPC SP1 shall be conducted wherever necessary.

NEW CONSTRUCTION STEEL - Prepare the surface by abrasive blasting to Sa 2½ as per ISO 8501- 1:2007. Surface shall have angular surface profile between 40-75μ. If oxidation occurs between the surface preparation and coating application, the surface shall be re-blasted to meet the specification.

MAJOR REFURBISHMENT/REPAIR STEEL - Substrates showing damage to the existing anti-fouling shall be spot blasted to Sa 2½ as per ISO 8501-1:2007. Edges of the spot blasted area must be feathered down to avoid lifting of the coating. After preparation, surface shall have angular surface profile (anchor pattern) of 40-75μ.

FIBREGLASS/WOOD - Substrate shall be power sanded in order to smoothen the texture of fiberglass and also to provide smooth transition between the laminate edges/welds. Aged wood or old wooden boat must be allowed to dry sufficiently before coating with the system.

Air temperature : 5 ~ 38℃, Surface temperature: 5 ~ 45℃

Relative humidity : below 85%

The surface temperature must be at least 3℃ above the dew point to prevent moisture condensation.
