International Intertherm 715

International Intertherm 715 is a single pack, temperature indicating paint, which exhibits a visual colour change in response to rising temperatures, identifying hot spots and internal insulation failures.

Please note, this product has a Minimum Order Quantity of 954 tins.

Best Uses

Intertherm 715 is normally used on reaction vessels on chemical and petrochemical sites as a one-time warning of dangerous temperature increases. It is suitable for application both on-site and in the fabrication yard.

Intertherm 715 can also be used in two coats as a self-priming system over stainless steel, or over an inorganic zinc primer for optimum corrosion protection to carbon steel substrates.

Application

The recommended application method for this product is Air Spray. Brush and Roller can be used for small areas only.

Ensure all surfaces are 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-SP6. If oxidation has occurred between blasting and application of Intertherm 715, the surface should be re-blasted to the specified visual standard.

Any surface defects that have been revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.

Shop Primed Surfaces
Intertherm 715 is suitable for application to unweathered steelwork freshly coated with zinc silicate shop primers.

If the zinc shop 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 SSPCSP6.

System Compatibility

Intertherm 715 can be applied directly to abrasive blast cleaned surfaces. However, if an improved anti-corrosive performance is required, Interzinc 22 is recommended.
