L-H06-12 Marine Thick Epoxy Paint
Product Description
L-H06-12 Marine Thick Epoxy Paint
Product Introduction:
L-H06-12 is a high-performance, two-pack epoxy primer engineered for heavy-duty corrosion protection in marine and industrial atmospheric environments. This thick-film coating delivers excellent adhesion to properly prepared steel substrates, combined with outstanding resistance to oil, salt spray, humidity, and a wide range of chemicals including water, saline solutions, and oil-based solvents. Its robust anti-corrosive properties make it an ideal choice for protecting critical steel structures exposed to aggressive conditions. With a VOC content of less than 420 g/L, it provides effective protection while meeting environmental compliance requirements. The product is formulated for easy application and offers reliable long-term performance, making it a trusted solution for both new construction and maintenance projects. The product has a volume solids content of 60% ± 2% and provides a matte (no gloss) finish. It is supplied as a two-component system with a mix ratio of 4.5:1 by volume (10:1 by mass).
The product is supplied in a convenient two-component packaging system: Part A (base) is provided in 20 kg / 9.5 L within a 20 L container, while Part B (curing agent) comes in 2 kg / 2.1 L within a 3 L container. Regarding safety and handling, the flash points are as follows: Part A is greater than 31°C, Part B is greater than 28°C, and the mixed paint has a flash point greater than 31°C, which should be taken into account during storage and application to ensure proper fire prevention measures are in place.
Intended Uses：
*For use in marine and industrial atmospheric environments.
*For protection of steel structures including ships, drilling platforms, port facilities, bridges, hydraulic facilities, and other steel installations.
Method Of Application:
*Airless Spray (Recommended): Tip size range 0.38–0.53 mm, output pressure ≥17 MPa.
*Air Spray: Tip size range 2.0–3.0 mm, output pressure ≥0.4 MPa.
*Brush/Roller: Suitable for small areas only.
*Thinner/Cleaner: Thinning is not recommended. Use HX-501 only in exceptional circumstances (maximum 5% by volume). Cleaner is also HX-501.

Storage:
Store in a cool, dry, and well-ventilated place, protected from direct sunlight, heat sources, and fire. Containers must remain tightly sealed. Shelf life is a minimum of 12 months at 25°C, subject to re-inspection thereafter.
System And Compatibility:
For the most suitable matching primer and coating system, please consult your Sunrui sales representative.
Surface Preparation:
All surfaces to be coated must be clean, dry, and free from contamination. High pressure fresh water wash or fresh water wash, as appropriate, shall be carried out, and all oil, grease, soluble contaminants, and other foreign matter shall be removed in accordance with SSPC-SP1 solvent cleaning.
*Abrasive Blast Cleaning: Abrasive blast clean to Sa 2½ (GB/T 8923.1-2011). If oxidation has occurred between blasting and application of L-H06-12, 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 (Repair): The areas to be repaired should be cleaned to P St3 (GB/T 8923.2-2008) by mechanical method. Abrade the area immediately surrounding the repair to provide a key for subsequent coating application. Overlap areas should be kept to a minimum.
Limitations:
1.This product will not cure adequately below 5°C. For maximum performance, ambient curing temperature should be above 10°C.
2.In common with all epoxy-based coatings, L-H06-12 will exhibit chalking of the film upon UV exposure (surface degradation, not a functional failure).
3.Apply only in good weather conditions. The surface temperature must be at least 3°C above the dew point, and ambient relative humidity must be below 85%.
4.Drying times and overcoating intervals may change according to on-site environmental factors.
Health And Safety:
Avoid prolonged inhalation of solvent vapors or paint mist. Prevent skin and eye contact with the product. Ensure adequate ventilation and take proper fire prevention measures during application.
