UN 1263 Quick Details
UN 1263
Product name: Paint related material (flammable)
DOT Class: 3
Placard type: Flammable
ERG Guide: 128 (check current ERG)

Common Hazards of UN 1263
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
Chemical Identity & Physical Properties
| Also known as | PaintPaint thinner mixtureLacquerEnamel paintSolvent-based paintCoating material |
| Appearance | Viscous liquid, color varies widely (clear to various pigmented colors). Odor ranges from mild to strong solvent-like depending on formulation. Liquid at room temperature. |
| Flash Point | Typically -4C to 23C (25F to 73F) depending on solvent content |
| Boiling Point | Variable, typically 35C to 150C (95F to 302F) depending on solvent mixture |
| Vapor Density | Heavier than air (typically 3-5), vapors will accumulate in low areas |
| Water Reactivity | No significant reaction with water, but insoluble and will float |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
