Winch Components for East Coast Maritime

Neumann Industrial Coatings were engaged by East Coast Maritime to paint the winch components for their vessel Pacific Titan, a 26m workboat.  The winch is a 40T double drum reverse waterfall anchor handling and towing winch.

East Coast Maritime's Pacific Titan

Works included:

Surface Preparation

All of the winch component were abrasive blasted (sandblasted) with steel grit media to a Sa 2.5 blast grading.

Painting

The winch components were then primed with a single coat of Jotun Barrier Grey. This is a two component polyamide cured zinc rich epoxy coating. It is a very high zinc dust containing product.

It was then undercoated with a single coat of Jotumastic 90, which is a two-pack surface tolerant, abrasion resistant, high solids polyamine cured epoxy mastic coating. And then a second coat of Jotumastic 90 Grey, which is s a two component polyamine cured epoxy mastic coating. It is a surface tolerant, high solids, high build product. It is reinforced with glass flakes for improved abrasion and scratch resistance.

The final two topcoats were Jotun Hardtop Ultra Black, Hardtop Ultra is a two-pack polyurethane topcoat suitable for application by brush or roller with excellent gloss and colour retention.

Materials Used

Product Description:

This is a two component polyamide cured zinc rich epoxy coating. It is a very high zinc dust containing product. It conforms to the compositional requirements of SSPC paint 20, level 2. It provides very good corrosion protection as part of a complete coating system. To be used as primer in atmospheric environments. Suitable for carbon steel, repair of inorganic zinc silicate coating and damaged galvanised steel substrates. This product complies with ASTM D520 type II zinc dust.

Intended Uses:

Suitable for structural steel and piping exposed in corrosivity categories up to CX (ISO 12944-2). Recommended for offshore environments, refineries, power plants, bridges, buildings, mining equipment and general structural steel. Specially designed as a primer for coating systems where extended durability is required.

Product Description:

This is a two-component polyamine cured epoxy mastic coating. It is a surface tolerant, abrasion resistance, high solids, high build product. This product is tintable in a wide range of colours in Jotun’s Multicolor Industry (MCI) system. Specially designed for areas where optimum surface preparation is not possible or desired.
