HMG Thinner 2604 is a slow, solvent-based thinner designed for use with recommended HMG coating systems. It is used to adjust the viscosity of compatible coatings for easier application, improved flow, and better control where a slower evaporating thinner is required. HMG lists the product code as TNR2604 and describes it as “a slow thinner for use in recommended HMG systems.”
It is commonly associated with HMG systems such as Acrythane ACE, Acrythane SC601, Monothane, Polykote primers, PVC17, and Acrythane XSC21. Supplier listings also describe it as a slow drying thinner recommended for large areas, helping maintain a wet edge, and for use in hot conditions; Online Paint Shop lists it for 2K Acrythane Top Coat and High Build Anti-Corrosion Primer.
Key details: flashpoint 24°C, store between 5°C and 25°C, keep cans sealed when not in use, and use within 12 months from delivery when kept in original sealed containers. Always refer to the SDS, product datasheet, and tin label before use.
Safety note: the safety data sheet identifies Thinner 2604 as for professional use only and for surface coating applications; it is not intended, labelled, or packaged for consumer use. It is classified as a flammable liquid and vapour and may be harmful if swallowed, cause skin irritation, cause serious eye irritation, may damage hearing organs through prolonged or repeated exposure, and may be fatal if swallowed and enters airways. Use good ventilation, keep away from ignition sources, and wear suitable eye protection, solvent-resistant gloves, and any respiratory protection required by the SDS or site risk assessment.
