Petrolatum paste, also known as petroleum jelly paste, is a thick and greasy ointment made from petroleum. It is commonly used as a protective barrier on the skin to help prevent moisture loss and soothe dry, chapped, or irritated skin. Petrolatum paste can also be used to treat minor cuts, burns, and diaper rash. It is non-comedogenic, meaning it does not clog pores, and is generally safe for all skin types.
| Waterpoofing for | buried or exposed or marine |
| Sealing for | pipes rods, cables, valves and metal fittings, tanks |
| Consist of | petrol tape,petrol mastic,petrol primer,outer wrap protection tape |
| Backing | Non-woven, stitch-bonded, synthetic fabric carrier |
Uses
For long-life corrosion protection,
sealing and waterproofing of atmospheric buried and submerged metal surfaces.
High degree of conformability
application over irregular surface profiles including gas utility, sewer, potable water, mining,
Application
55% overlap for all applications,
For vertical applications the tape shall begin at the bottom and proceed up – providing a“weatherboard” overlap.
“cigarette wrapped” when space is too restricted or confined to apply in the preferred spiral manner, with the overlap on the topside of the pipe –providing a “weatherboard” effect.At the completion of each roll, smooth the overlaps by hand. Maintain a 100mm overlap when overlapping one roll with the end of a new roll.
