What it is and why choose it
THINNER A CR / ACRI by Chugoku is a xylene-based thinner specifically designed for use with most chlorinated acrylic paints and antifouling coatings. Supplied as a clear, colourless liquid with a typical solvent odour, it is formulated to ensure proper application viscosity and flow while maintaining the performance of compatible marine and protective paint systems.
This thinner is suitable for a wide range of Chugoku products, including CMP AC, the ACRI series, SEA GRANDPRIX series, SEATENDER series and SEAFLO NEO series. When used as directed (usually not more than 5% addition), it helps optimise spray characteristics and surface appearance without compromising coating properties.
Main features
- Xylene-based formulation for controlled thinning of compatible chlorinated acrylic and antifouling paints.
- Wide product compatibility with selected Chugoku coating systems (CMP AC, ACRI, SEA GRANDPRIX, SEATENDER, SEAFLO NEO).
- High solvent strength to adjust viscosity effectively with low addition levels (normally ≤ 5%).
- Clear, colourless liquid that does not affect the colour of the paint.
- Typical aromatic solvent odour for easy identification during use.
- Flammable liquid and vapour (flash point approx. 25–26°C) requiring careful handling and storage.
- High VOC content (theoretical 870 g/l) suitable for professional and industrial coating operations.
- Formulated for European requirements; some physical properties may differ from the original Japanese data sheet to meet local regulations.

Section 8 – Personal protective measures
Personal Protection advice and additional information are given in the Safety Data Sheet. Minimum safety precautions when handling THINNER A CR / ACRI include:
- General measures: Observe precautionary notices on the container. Provide adequate ventilation and avoid breathing vapours, spray mist or sanding dust. Keep away from heat, hot surfaces, sparks and open flames. No smoking.
- Respiratory protection: If workers may be exposed above occupational exposure limits, use a respirator to EN 140 fitted with a combined particulate and vapour filter to EN 14387 with an assigned protection factor of at least 10 (e.g. A2P3). When working inside spray booths where ventilation is insufficient, use a compressed air-fed respirator during spraying and until vapour and particulate levels are below exposure limits.
- Hand protection: Use chemical-resistant gloves tested to EN 374. Suitable materials include nitrile (good for spray application), polyethylene (PE), PVA and butyl/Viton gloves, with thickness and breakthrough times selected according to exposure duration as indicated in the Safety Data Sheet. Replace gloves regularly and immediately if damaged.
- Eye and face protection: Wear safety eyewear to EN 166 designed to protect against liquid splashes.
- Skin and body protection: Wear anti-static protective clothing made from natural fibre or high-temperature-resistant synthetic fibre. Avoid skin contact; remove contaminated clothing and wash skin thoroughly with soap and water.
- Environmental protection: Prevent product from entering drains, sewers or watercourses.
