Technical datasheet for SMP sulfonated phenol-formaldehyde resin detailing properties, quality indexes, storage and packaging.
The SMP sulfonated phenol-formaldehyde resin is used in salt‑water drilling mud containing calcium under high temperature and high pressure to reduce filtration, prevent borehole collapse, and lubricate drilling tools.\n\nThe document lists key quality indexes such as appearance, moisture content, pH, chloride concentration and filtration, and describes packaging options for both liquid and powder forms.
| Appearance | Brown(red) or yellowish powder |
|---|---|
| Moisture | ≤10.0% |
| pH | 9.0-10.5 |
| Chloride concentration | 100.0-160.0 g/1 |
| Filtration | ≤25.0 ml |
SMP reduces filtration, prevents borehole collapse, and lubricates drilling tools in salt‑water drilling mud containing calcium under high temperature and high pressure.
Liquid SMP is packed in 25 kg or 50 lb barrels, while powder SMP is packed in woven sacks with plastic lining, 25 kg per sack, each labeled with product name, manufacturer, lot number and net weight.
