International Intertherm 50 is a single pack, aluminium pigmented silicone resin coating that is heat resistant up to 540°C.
International Intertherm 50 is suitable as a light reflective primer / finish for surfaces that can reach dull red heat of up to 540°C, such as exhaust stacks. For use at Newbuilding, Maintenance & Repair or On Board Maintenance.
Use in accordance with the standard Worldwide Marine Specifications. All surfaces to be coated should be clean, dry and free from contamination. High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.
PREPARATION FOR NEWBUILDING
Intertherm 50 is suitable for application to 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. Ensure that the zinc primer is fully cured prior to the application of Intertherm 50 by following the curing instructions on the relevant product data sheet. 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).
PREPARATION FOR MAJOR REFURBISHMENT
Abrasive blast clean to Sa2½ (ISO 8501-1:2007).
PREPARATION FOR REPAIR / OBM
Intertherm 50 may be applied directly over aged Intertherm 50 following thorough fresh water washing and degreasing provided the coating to be overcoated is in an intact and tightly adherent condition. Loose or flaking coatings should be removed back to a firm edge and Intertherm 50 or an appropriate primer should be used to repair the area before application of the full coat.
This material is a one pack coating and should always be mixed thoroughly with a power agitator before application. Apply using airless spray, conventional spray, brush or roller.
