Product Description

International Intertherm 181 is a two component, high temperature resistant pipework topcoat based on inorganic silicate technology.

Best Uses

Intertherm 181 has been specifically designed for application over inorganic zinc primers, which provides a single specification to be used for the protection of all pipework from corrosion at continuous operating temperatures up to 400°C (752°F), and intermittent temperature surges up to 500°C (932°F).

Intertherm 181 is ideally suited for use in the petrochemical industry, especially refineries and offshore structures, where significant volumes of insulated and uninsulated pipework can be coated with a single specification at works, reducing complexity of work schedules etc.

Application

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Metallic Zinc Primed Surfaces
Intertherm 181 should always be applied over a recommended zinc based primer. Intertherm 181 is suitable for application to steelwork freshly coated with zinc silicate primers. If the zinc silicate primer shows extensive or widely scattered breakdown, or excessive zinc corrosion products, overall sweep blasting will be necessary. Other types of shop primer are not suitable for overcoating and will require complete removal by abrasive blast cleaning.

Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 (or SSPCSP10 for optimum performance), and reprime with zinc silicate. Ensure that the surface of the primer is clean, dry and free from contamination and zinc salts before application of Intertherm 181. Ensure zinc primers are fully cured before overcoating.

Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the
working pot life specified. Agitate Base (Part A) with a power agitator. Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.
