The Guardian Butylwrap System
Butylwrap MP Primer
The Guardian Butylwrap MP Primer system consist of butyl-based elastomers blended with polymeric resins dissolved in an organic solvent system. It can be used for machine or hand brush applications, and provide excellent adhesion to the pipe substrate and cathodic disbandment resistance.
A liquid adhesive system is ideal for hand brush applications to rough and reconditioned grit-blasted pipe surfaces. It provides a uniformly smooth, instant tack surface for coating systems.
Caution: The Butylwrap MP Primer is FLAMMABLE. Store away from heat sources. Read all label instructions prior to use. Please request an application specification and storage guideline from Seal for Life.
The Guardian Butylwrap MP Primer is an excellent adhesion, has superior cathodic disbandment resistance and ensures permanent bonding of coating systems. We recommend using it for the prevention of corrosion on metallic pipelines. Also, it can be easily customized to fit local and national standards.

The Guardian Butylwrap is a wraparound corrosion protective coating, consisting of one layer of epoxyprimer and two layers of PE film. The product is used in a wide range of applications where products or installations need to be sealed against air and water ingress.
It can be used for the coating of pipes, coating of risers, coating of flanges, coating of manholes, coating of valves, underwater coating of riser, coating of welded sockets, repair of all type of coatings, sealing of pipe and cable conduits, sealing of pipe casings, which are constantly exposed to elevated temperatures.
Guardian Butylwrap 1080/1055 is a multilayer system used for the protection of steel pipelines, Liquid Adhesives can be used as primers for this system. The inner layer of Butylwrap 1080 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer (out layer) of Butylwrap 1055, achieves a complete bond to the Butylwrap 1080 inner layer.
It can save time without preheating, and achieves superb bonding to PE, PP, FBE and AE. Moreover, it has a long shelf-life, is impermeable to water oxygen, and its superior cathodic disbandment offers the optimum barrier for long term protection against corrosion.
