Best Uses

International Intertherm 875 is ideal for use in a wide range of industrial environments including petrochemical plants, oil refineries, offshore structures, chemical plants and power stations. Suitable for areas subject to intermediate service temperature that require a coloured finish.

International Intertherm 875 is a heat resistant finish coat for application over properly primed steelwork. For use at both new construction and as a maintenance coating. Suitable for steelwork operating at temperatures up to 260°C (500°F). Does not require heating between coats.

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.

Abrasive Blast Cleaning
Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation has occurred between blasting and application of Intertherm 875, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.

Intertherm 875 can be applied over approved anti-corrosive primers. The primer surface should be dry and free from all contamination, and Intertherm 875 must be applied within the overcoating intervals specified (consult the relevant product data sheet). In the case of zinc primers, where necessary, remove weld spatter, smooth weld seams and sharp edges and blast clean welds and damaged areas to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. The shop primer or other primer surface should be dry and free of all contamination (oil, grease, salt etc) and overcoated with Intertherm 875 within the overcoating intervals specified for the primer (consult the relevant product data sheet).

Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. Ensure the zinc primer has fully cured and is clean, dry and free from zinc salts prior to overcoating. If the shop primer shows extensive or widely scattered breakdown overall sweep blasting may be necessary.

This material is a one component coating and should always be mixed thoroughly with a power agitator before application.
