What is UNY MARINE HS M PART A and why choose it?
UNY MARINE HS M PART A is the base component of a high-solids, high-build polyurethane finish from Chugoku. Based on acrylic polyol and non-yellowing poly-isocyanates, it is designed as a durable glossy topcoat for demanding industrial and marine environments. When mixed with its dedicated hardener, it delivers long-term gloss and colour retention, strong mechanical resistance and excellent adhesion to properly prepared primers.
This base is suitable for professional coating systems on steel structures, bridges, wind turbines, chemical and petrochemical plants, power generation facilities and other metal structures where a tough, chemically resistant polyurethane finish is required.

Section 8 – Personal protective measures
General exposure controls
- Provide adequate ventilation using local exhaust and general extraction to keep solvent vapour and spray mist below occupational exposure limits.
- Avoid inhalation of vapours, spray mist and sanding dust.
- Prevent the product from entering drains or watercourses.
Respiratory protection
- If exposure may exceed limits, use a respirator conforming to EN 140 with a combined particulate and vapour filter to EN14387 and an assigned protection factor of at least 10 (for example A2P3).
- During spray application in booths where ventilation is insufficient, use compressed air-fed respiratory protection until vapour and particulate levels are below exposure limits.
Hand protection
- Use chemical-resistant gloves tested according to EN 374.
- Polyethylene (PE) and polyvinyl alcohol (PVA) gloves are indicated in the SDS for high protection, with minimum thickness around 0.062 mm for PE and 0.2–0.3 mm for PVA (depending on exposure time).
- Nitrile gloves provide good protection during spray application; Viton gloves are suitable for intense solvent contact.
- Glove breakthrough time should exceed the actual working time; replace gloves at first sign of damage.
- PE gloves may be used as under-gloves in difficult situations such as high or unknown exposure.
Eye and face protection
- Wear safety eyewear tested to EN 16321 / EN 166, designed to protect against liquid splashes.
Skin and body protection
- Wear suitable protective clothing, including anti-static garments of natural fibre or high-temperature-resistant synthetic fibre (EN ISO 13688).
- Avoid repeated or prolonged skin contact; use protective creams only on clean skin before exposure.
Additional safety notes from SDS
- The product is classified as a flammable liquid and vapour and may cause drowsiness or dizziness and an allergic skin reaction; repeated exposure may cause skin dryness or cracking.
- Keep away from heat, hot surfaces, sparks and open flame. No smoking during handling or application.
- Do not use pressure to empty containers; they are not pressure vessels.
