The PPG LP144 multi-purpose epoxy series datasheet details its properties, application methods, and specifications for protective coatings.
LP144 is a multi‑purpose epoxy coating that forms a tough, abrasion‑resistant and durable film with excellent adhesion to steel, galvanized steel, aluminum and inorganic zinc surfaces. It is intended for use as a primer/middle coat on steel structures, equipment, tanks, pipelines and marine, power, petro‑chemical and ship applications.
The datasheet provides application guidelines such as airless or conventional air spraying, recommended dry film thickness of 100‑200 µm, mixing ratio 4:1 with LN141‑20 thinner, pot life of 4.5 hours at 21 °C, and surface preparation standards (e.g., SSPC‑SP6 for new steel). Technical specifications include VOC, spreading rate, volume solids and spraying parameters. This manual is written in Chinese.
| Recommended dry film thickness | 100‑200 µm |
|---|---|
| VOC | 292 g/L (2.4 lb/gal) |
| Theoretical spreading rate (100 µm DFT) | 7.8 m²/L |
The recommended dry film thickness is 100‑200 µm.
New steel should be blasted to SSPC‑SP6 (Sa2) standard.
Yes, it is a versatile shop‑applied primer for offshore, marine, power, petro‑chemical and ship structures.
