Specifications

Technical documents and conditions of use

See the technical documents below for specification sources and conditions. Verify the exact grade and document version before application. Specification sources

This document covers the relevant product series. Confirm the exact model, substrate preparation, mixing ratio, dry film thickness, temperature, humidity, curing and test conditions. Typical series values are not guaranteed values for every application.

Verify performance and service-life statements against the relevant reports, specimen preparation, test standards and service conditions. Service-life figures without supporting reports are not durability guarantees; site photographs do not replace film-thickness testing or project acceptance records.

Features

  • Without additional layers of protection, suitable for ship decks, hulls, cabins, etc., corrosion protection scenarios, especially for equipment such as oceanic vessels, offshore ships, yachts and other long-term exposures to the marine environment and outdoors, and protection against suntan, ocean atmospheric erosion and long-term immersion of seawater
  • Elongation at break exceeds 200%, accommodating hull movement during sailing and minor wave-induced deformation while bridging fine cracks at welds, joints and surfaces. A dense three-dimensional network blocks seawater, oxygen and marine salts to prevent rust, corrosion and leakage, accommodating deformation in ship steel structures and hull shells.
  • Waterproofing depends on substrate preparation, specified film thickness and detailing. Conduct the project-specified water test after full cure.
  • Review the grade-specific SDS, emissions data and ventilation requirements before use. Wear appropriate protective equipment. Drinking-water or food-contact applications require specific evidence and approval for the intended use.
  • Select the coating according to actual mechanical loads, chemical media, concentration, temperature and exposure. Confirm suitability by testing and establish an inspection and maintenance plan.
  • It can also be demagogized, based on the use of ships and shipping management needs, to integrate corrosion protection with marking, to balance protective and cognitive properties, and to facilitate the classification of ship parts and routine inspections.

Selection guide

Marine corrosion protection requires distinguishing the service environments of decks, hulls and compartments. Compare seawater and salt-spray exposure, hull movement and surface wear rather than selecting solely on appearance or adhesion results from ordinary building coatings.

Formulation notes

Confirm marine atmospheric exposure and prolonged seawater immersion separately, including welds and joints in the system review. For special compartments or drinking-water or food-contact uses, verify the relevant test documents and project requirements rather than relying on general corrosion-resistance descriptions.
