Applications:

Coating & Wrapping Application

In order to properly apply coating and wrapping to a surface, it is important to follow specific guidelines:


Temperature Requirements

The volume solution temperature of the surface being coated or wrapped must be maintained at or above 5℃. Additionally, the actual application should take place at a temperature of 5℃ or higher to ensure proper adhesion and curing.


Application Process

First, apply a thin coat of paste to the area. The paste should be applied to threads, cavities, shoulders, pits, and other irregularities. This will ensure that the paste fills in any crevices or gaps, creating a smooth surface for further coating and wrapping.


In areas with more significant irregularities, such as flanges and valves, stuff mastic into the uneven areas. The mastic should be molded and packed into the irregularities to eliminate bridging and voids.


Wrapping Process

Once the paste and mastic have been applied, wrap petrolatum tape tightly around the surface. This will ensure that the tape adheres firmly and creates a water-tight seal.


Finally, to protect the petrolatum tape from mechanical damage and provide better isolation from air, it is recommended to wrap PVC tape around the outside layer of the petrolatum tape.
