1.Use:pipe synthetic primer
2.Compatibility:special paint for Pipecoat corrosion prevention tape to add adhesiveness of tape
Corrosion protection primer
Primer is made up of butyl rubber, unsaponifiable resins, tackifier, stabilizer, and solvent.
The primer is applied to the appropriately prepared pipe surface before application of inner layer tape.
It is used for improving bonding strength and sealing between the anticorrosion tape and the steel pipeline.
AP primer is to support PipeCoat series to play its feature to the greatest extent. And PipeCoat tape must make use of AP primer. The operation of AP primer is simple with fast drying (at normal temperature, only 5-10minutes is required for drying), no consolidation is demanded, after drying, can start winding of tape immediately.
Conformable to irregular pipe
Compatible with general coating system
pipe coating primer
Paint the primer on the pipeline without rust evenly. Waiting until the surface is dry, and then wrap the tape on the pipe tightly and smoothly. For repairing of the local damage of tape, the primer should also be painted first before sticking the tape. Before use, the primer should be shaken or stirred until it is even. If the primer is too thick for evaporation, additional solvent may be used for dilution.
Purpose of AP primer:
1. With completion of surface pretreatment, steel surface may be uneven, primer may fill such unevenness to form a smooth film to increase contact area of pipe with adhesive layer for a strong bonding force.
2. After pretreatment of pipe, primer may be able to get rid of dust on the pipe surface.
3. The moisture of pipe surface will volatilize with AP primer, thus reducing possibility of corrosion.
Time interval from pretreatment to paining of primer shall be within 4 hours, and timer interval from primer painting to winding of tape shall be within 8 hours and the primer surface shall be dry and without dust (winding of tape on very windy or humid days is not suggested).
For use of AP primer, primer shall be mixed and stirred to be even in a container. If primer is thick, add some thinner to dilute. Make use of clean brush, roll and other mechanical methods to paint primer. The primer painted on pipe shall not have missed spots, no bubbles, blots or dripping, and even film is to be formed. Each liter of primer shall cover pipe area 10-12 m2 with manual operation. With drying of primer, start winding of adhesive tape.
