H45-ZF101G Marine Heavy-Duty Anticorrosive Coating
Product Description
H45-ZF101G Marine Heavy-Duty Anticorrosive Coating
Product Introduction:
H45-ZF101G is a high-performance, two-pack epoxy heavy-duty anticorrosive coating specifically engineered to provide exceptional protection for steel and concrete substrates exposed to the most aggressive marine and industrial environments. This advanced formulation delivers outstanding adhesion to properly prepared surfaces, combined with excellent resistance to chemicals, fresh water, seawater, and corrosion, making it the ideal choice for both atmospheric and submerged service conditions. Its unique high-build capability allows for application at extremely high film thicknesses in a single coat, significantly reducing application time and labor costs while ensuring robust, long-lasting protection. With an exceptionally high volume solids content of 85% ± 2% and an ultra-low VOC level of less than 180 g/L, H45-ZF101G offers maximum application efficiency with minimum environmental impact, far exceeding conventional coating systems in both performance and sustainability. The coating cures to a glossy finish with a mix ratio of 3.4 : 1 by volume, providing a dense, impermeable barrier that effectively isolates the substrate from corrosive attack. Designed primarily for heavy-duty corrosion protection of steel or concrete structures in outdoor and underwater zones, including docks, harbors, and marine facilities, this coating also excels in demanding industrial applications such as the interior lining of steel pipes and concrete structures in petrochemical plants, power stations, and wastewater treatment facilities. When applied as part of a complete protective system, H45-ZF101G delivers the ultimate in corrosion resistance, mechanical strength, and long-term durability, ensuring structural integrity and minimal maintenance even under the most challenging exposure conditions. Its proven performance in both new construction and maintenance scenarios makes it the preferred heavy-duty coating solution for engineers specifying protective systems for critical marine and industrial infrastructure.

Surface Preparation:
All surfaces to be coated must be clean, dry, and free from contamination. High-pressure fresh water washing or appropriate fresh water washing should be carried out, and all oil, grease, soluble contaminants, and other foreign matter must be removed in accordance with SSPC-SP1 solvent cleaning standard.
Abrasive Blast Cleaning For Steel:
Steel surfaces should be abrasive blast cleaned to Sa2.5 (GB/T 8923.1-2011). If oxidation has occurred between blasting and the application of H45-ZF101G, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.
Mechanical Cleaning For Steel (Repair):
Areas to be repaired should be cleaned to St3 (GB/T 8923.2-2008) by mechanical methods. The area immediately surrounding the repair should be abraded to provide a key for subsequent coating application, and overlap areas should be kept to a minimum.
Mechanical Cleaning For Concrete:
Concrete surfaces can be abraded by power tool or washed by low-pressure water to remove loose concrete, attached organisms, mud, and other contaminants. If necessary, scrubbing with scour or chemical washing should be employed to remove oils, grease, wax, fatty acids, and other contaminants. Repair areas should be thoroughly cleaned to remove loose powder, attached organisms, mud, oil, grease, and other foreign matter. The area immediately surrounding the repair should be abraded to provide a key for subsequent coating application, and overlap areas should be kept to a minimum.
Method Of Application:
*Airless Spray (Recommended): Tip size and output pressure details not specified in the provided documentation. Consult your Sunrui representative for specific application parameters.
*Air Spray: Application parameters not specified.
*Brush / Roller: Suitable for small area application only.
Mixing Instructions:
The two components must be mixed thoroughly in the specified ratio of 3.4 : 1 by volume. Refer to the product data sheet for specific mixing procedures.
Thinner And Cleaner:
Consult your Sunrui representative for recommended thinner and cleaning solvent.
Flash Point:
The product has a high flash point, with Part A and the mixed paint exceeding 31°C, and Part B exceeding 29°C, ensuring safe handling under normal conditions.
Storage And Shelf Life:
Store in a cool, dry, and well-ventilated area, protected from direct sunlight, fire, and heat sources. Containers must remain tightly sealed. At 25℃, the product has a minimum shelf life of 12 months (subject to re-inspection thereafter).
Limitations:
1.Apply only in good weather conditions. The surface temperature must be at least 3℃ above the dew point, and ambient relative humidity should be below 85%.
2.In common with all epoxy-based coatings, H45-ZF101G will exhibit chalking of the film upon UV exposure. It should therefore be topcoated for exterior applications where UV resistance is required.
3.Drying times and overcoating intervals may vary due to on-site environmental conditions.
4.Avoid prolonged inhalation of solvent vapors or paint spray. Prevent skin and eye contact. Ensure adequate ventilation and fire prevention measures during application.
