摘要： Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, are formed from a coating composition comprising a substantially non-zinc containing primer and a topcoat. The primer includes an epoxy resin having an epoxy equivalent weight of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a hydroxyl equivalent weight of about 200 to about 500, and a filler material. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 520 to about 930, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a carboxyl functional polyester with an acid number of about 45 to about 75 mg KOH/g, a foaming agent and a reinforcing fiber.

摘要： Zonal isolation tools and methods of using same are described. The zonal isolation tools include a wellbore sealing member expandable by fluid pressure to contact a wellbore over an initial contact area, an inflation valve open during expansion of the sealing member to the initial contact area and closed upon the fluid pressure reaching a predetermined setting, a vent between the sealing member and a wellbore annulus adapted to open after the inflation valve is closed, and a compressive load imparted to the sealing member via a linear piston to achieve a sealing point at the leading edge of the sealing member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.
