Description

Tapecoat TC 7030 High-Build, High-Temperature Epoxy is a one-coat, stand-alone protection that exceeds all performance criteria for prevention of corrosion of above and below ground metal surfaces. This tough coating can be used for any general application including high temperature pipelines with a maximum constant operating temperature of up to 250°F (121°C).

TC 7030 is an environment-friendly two-component, 100% solids material that provides up to 30 mils of high-build thickness for tough abrasion resistance-to-backfill and soil stress damage. This surface-tolerant epoxy provides exceptional corrosion prevention for reconditioning pipelines, protecting joints, patching pipeline coatings, and covering irregular fittings and metal surfaces.

Application

Surface must be clean and dry. Commercial blast to SSPC-SP6. Remove oil and grease with suitable solvent. Salt and other contaminants may be removed by high pressure fresh water cleaning. Pour entire contents of Part B Curing Agent (small container) into Part A Resin (large container), and mix thoroughly for approximately 3 to 5 minutes. Do not alter the amounts of A and B in the mixture. Apply epoxy by brush, pad, roller or spray.

Primer should be dry to touch before applying Tapecoat hot applied tapes or sleeves. As a stand alone coating, TC 7030 Epoxy provides superior corrosion protection above and below ground.

Specially selected Tapecoat reinforcing scrim can be applied over wet epoxy. After scrim has been applied, apply a second coat of TC 7030 Epoxy.
