Winch Components for ECM
Neumann Industrial Coatings were engaged by East Coast Maritime (ECM) 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.
Scope of Works
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
Jotun - Barrier - Polyamide Cured Epoxy
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.
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.
Jotun – Jotamastic 90 – Polyamine Cured Epoxy Mastic
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.
Provides long lasting protection in environments with high corrosivity. Can be used as primer, mid coat, finish coat or as single coat system in atmospheric and immersed environments. Suitable for properly prepared carbon steel, galvanised steel, stainless steel, aluminium, concrete and a range of aged coating surfaces. It can be applied at sub zero surface temperatures.
General: Primarily designed for maintenance and repair.
Marine: Outside hulls, exterior and interior areas.
Protective: Recommended for offshore environments, including splash zones, refineries, power plants, bridges, buildings, mining equipment and general structural steel.
Jotun – Hardtop Pro – Polyurethane
This is a two component chemically curing acrylic polysiloxane coating. It is a high solids product. It has a high gloss finish. It has excellent gloss and colour retention. It has very good mechanical properties and chemical resistance. To be used as topcoat in atmospheric environments. The product is fully recoatable at any stage of curing. It cures down to 0 °C. The product does not contain isocyanates, neither does it generate di-isocyanates during hotwork / welding or fire.
Protective: Recommended for offshore structures, tank farms, refineries, power plants, bridges and buildings. Suitable for a wide range of industrial structures.
Marine: Recommended for topside, deck and superstructure.
