What is EPICON T-800 PART A and why choose it?
EPICON T-800 PART A is the base component of a two-pack, high-build epoxy phenolic coating developed by Chugoku for heavy-duty anticorrosive protection. When mixed with its hardener, it forms a chemically resistant lining for storage tanks and transfer piping, delivering excellent adhesion, toughness and abrasion resistance. It is suitable for use in product carrier tanks, crude oil tanks, chemical tanks and associated pipework, and meets strict international standards for aviation fuel and cargo oil tank protection.
This base component is formulated to provide outstanding resistance to salt water, fresh water, petroleum products, crude oil, alkalis and weak acids, while allowing high dry film thickness per coat by airless spray. It is certified as an IMO PSPC-approved coating for cargo oil tanks (COT) and complies with EI 1541 for aviation fuel storage systems, making it a reliable option for demanding marine, industrial and terminal environments.

Yes. EPICON T-800 is IMO PSPC type-approved for cargo oil tanks (COT), making it suitable for use as part of approved COT protective systems.
-
What mixing ratio should I use for Part A and the hardener?
The recommended mixing ratio is 84 parts base (EPICON T-800 PART A) to 16 parts hardener by volume.
-
Which thinner should be used?
The product is designed to be thinned with EPOXY THINNER B (0–10 % by volume). In some regional documents EPOXY THINNER A or D is also indicated; follow the project specification.
-
What is the recommended film thickness per coat?
By airless spray, apply 115–246 µm wet film thickness to obtain 75–160 µm dry film thickness per coat.
-
Can I apply it by brush or roller?
Yes. Brush and roller application are allowed, but more coats may be required to achieve the specified dry film thickness. Stripe coating of edges and welds is recommended.
-
What surface preparation is needed for maintenance work?
Remove oil, grease, salts and contaminants by high-pressure fresh water cleaning and thorough drying. Then abrasive blast damaged areas to Sa 2½ or power tool clean to St3 as a minimum.
-
How important is ventilation inside tanks during curing?
Ventilation is essential. In confined spaces such as tank interiors, continuous forced ventilation must be provided during and after application to remove solvent vapours and promote proper curing.
-
Does the coating chalk or fade outdoors?
Yes. As with other epoxy coatings, EPICON T-800 may chalk and fade when exposed to sunlight; this is a surface effect and does not necessarily indicate loss of protective performance.
-
Where can I find detailed chemical resistance information?
For specific cargo or chemical resistance, you should consult your local CMP representative.

Section 8 – Individual protection measures
Exposure controls
- Engineering controls: Provide effective local exhaust ventilation and general extraction to keep solvent vapour and particulates below occupational exposure limits. Use spray booths or local exhaust for spray application.
- Environmental controls: Prevent the product and its residues from entering drains, sewers or watercourses.
Personal protective equipment (PPE)
- Respiratory protection:
- When exposure may exceed limits, use a respirator conforming to EN 140 fitted with a combined particulate and vapour filter to EN 14387 with an assigned protection factor ≥ 10 (e.g. A2P3).
- During spray application in booths or confined spaces, use compressed air-fed respiratory protection until vapour and particulate concentrations are below limits.
- When dry sanding, flame cutting or welding old coatings, provide local exhaust ventilation and/or appropriate respiratory protection, as these operations can generate hazardous dust and fumes.
- Hand protection:
- Use chemical-resistant gloves tested according to EN 374.
- Recommended materials: Nitrile gloves for general application; Viton/butyl gloves for intense or immersion contact with solvents; polyethylene (PE) gloves as under-gloves in high-exposure or uncertain conditions.
- Typical minimum thicknesses (PE gloves): 0.062 mm; other materials as specified in the safety data sheet.
- Replace gloves regularly and immediately when damaged; follow the glove manufacturer’s instructions for use and service life.
- Eye and face protection:
- Wear chemical splash goggles or equivalent eye protection tested to EN 16321 / EN 166.
- Where splashing or spray mist may occur, consider additional face protection.
- Skin and body protection:
- Wear antistatic protective clothing made from natural fibres or high temperature–resistant synthetic fibres (EN ISO 13688).
- Use appropriate protective footwear and avoid static-generating materials.
- Hygiene measures:
- Avoid skin and eye contact and inhalation of vapours or spray mist.
- Do not eat, drink or smoke in application areas.
- Remove contaminated clothing immediately and wash skin thoroughly with soap and water; never use solvents or thinners for skin cleaning.
