3M™ Scotchkote™ Fusion Bonded Epoxy Coating 134 1 - Introduction

The cost of the coating is only a small fraction of the cost of a tubing string, yet the coating is the major means of assuring extended operation by preventing deterioration and service disruption due to corrosion loss . 3M™ Scotchkote™ Fusion Bonded Epoxy Coatings represent a significant improvement in internal coating technology for the oil, gas and water industries .

2 - DescriptionScotchkote fusion bonded epoxy coating 134 is a one - part, heat curable, thermosetting epoxy coating designed for corrosion protection of metal . The epoxy is applied to preheated steel as a dry powder which melts and cures to a uniform, coating thickness . This bonding process provides excellent adhesion and coverage on applications such as valves, pumps, pipe drains, hydrants and porous castings . Scotchkote 134 FBEC assistant to waste water, corrosive soils, hydrocarbons, harsh chemicals and sea water . Powder properties allow easy manual or automatic application by electrostatic or air - spray equipment . When applied over a suitable primer, it is appropriate for operation at moderate temperatures and pressures in the presence of H2O, CO2 and CH4, crude oil and brine .

Scotchkote 134 FBEC consists of a blend of epoxy resin and curing agent additives, pigments, catalysts, leveling and flow control agents . Possible combinations of raw materials are extensive; hence careful selection has been made by 3M so that the resultant coating will serve in the environment encountered . Scotchkote 134 FBEC has been designed to allow trouble - free, consistent production application at the coating plant . Selection of the chemical elements for the fusion bonded epoxy coating is very important . The molecular structure of the epoxy resin, the type and reactivity of the hardener, catalyst and additives all play an important role in the ultimate coatability and performance of the fusion bonded epoxy .

3M Company maintains a divisional laboratory group dedicated to the research and development of fusion bonded epoxy coating . The group’s personnel have many years of experience in the formulation and evaluation of epoxy coatings . This effort is assisted by 3M staff laboratories with broad - based expertise in scientific disciplines applicable to coating and surface technology . In addition, 3M synthesizes and manufactures specialized epoxy resins, hardeners, catalysts and additives used to formulate Scotchkote FBE coatings to meet unusual performance and operational requirements .

3 - HistoryScotchkote 134 FBEC has been used extensively in the oil and gas industry to coat the exterior and interior of line pipe . Over 40,000 miles (65,000 km) of Scotchkote coated pipe have been installed thoughout the world . This technology has been expanded through 3M research to develop chemically stable, high temperature/pressure resistant internal linings for use in drill pipe, primary and secondary recovery tubing, and pipe for oil, gas and water transportation . Coating properties have been proven by rigorous 3M autoclave testing, and the results verified by independent laboratory and customer investigation .

4 - ManufacturingAll Scotchkote fusion bonded epoxy coating powders are made using the fusion blend process developed by 3M . Ingredients are first pulverized, properly proportioned and homogeneously dry mixed . Next, the blended materials are carefully and thoroughly mixed in the molten state using a continuous melt mixer . The fused blend is cooled and then pulverized into the final powered form . Particle size distribution is carefully monitored to meet optimum application standards required by the various coating plants . The fusion blend process assures that each particle of the coating powder contains all active ingredients, thus eliminating changes in reactivity due to separation or stratification of ingredients during transportation and application .

5 - Process and Quality ControlProcess control is essential to the quality of the finished product . 3M maintains rigid incoming quality inspection of raw materials, precise measurement and metering of critical components, controlled environmental conditions and processing temperatures for the chemical constituents, and a discerning outgoing inspection of the finished coating powder to assure uniformity of product application and performance . Among the quality control tests performed on 3M powder coatings are: gel time, cure, flow, fluidization, particle distribution, adhesion, impact, appearance and moisture content .

6 - Packaging, Storage and Shipping

Scotchkote 134 FBEC is packaged in a heavy duty, polyethylene bag in a stout, easy open, fiberboard carton which is clearly labeled with product number and manufacturing identification . This package protects the coating powder from humidity and contamination during shipment and storage . The net weight is 65 U .S . lbs . (29 .5 kilos) . The sealed cartons are palletized on wooden pallets with net weight of 1170 lbs . (530 kilos) and securely banded for shipment . The packaged product must be shipped and stored at temperatures not exceeding 80˚F (27˚C) .
