HMG Thinner 2642 is a medium-slow, solvent-based thinner designed for use with cellulose-based HMG coating systems. It is used to adjust the viscosity of compatible cellulose paints and coatings for easier application, improved flow, and the correct finish where HMG specifies Thinner 2642 in the relevant product datasheet. HMG lists the product code as TNR2642 and describes it as a medium-slow thinner for cellulose-based systems.
It is commonly associated with HMG cellulose products such as Industrial Cellulose, M99 Cellulose, and Cellulose APS Primer. Bailey Paints also identifies HMG 2642 as a solvent-based thinner and lists it as particularly suitable for M99 Cellulose.
Key details: flashpoint -17°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 2642 as for industrial and professional use only and for surface coating / thinner applications. It is classified as a highly flammable liquid and vapour and may cause skin irritation, serious eye damage, respiratory irritation, drowsiness or dizziness; it is also suspected of damaging the unborn child, may cause hearing-organ damage through prolonged or repeated exposure, may be fatal if swallowed and enters airways, and is harmful to aquatic life with long-lasting effects. 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.
