ISO12944-2 Specifications
21/10/1999
C1MGS : C1; Medium Durability; Standard Cure
A high durability coating specification designed for environments classified by ISO 12944-2 as C1 very low corrosivity.
Surface Preparation & Commentsl Abrasive blast clean to Sa2½ (ISO 8501-1:1988) or SSPC-SP6 (SSPC-SP10 for optimum performance).
If oxidation has occurred between blasting and application, 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.
l Within the North American region it is possible to substitute Interseal 670HS for fabricator friendly Intergard 345 which offers rapid drying/hard dry properties.
l When cosmetic considerations are important it is recommended that this system is topcoated with either Interfine 629HS (e.g. interior) or Interthane 990

C2MGS : C2; Medium Durability; High Gloss; Standard
A medium durability (5 to 15 years) coating specification designed for environments classified by ISO 12944-2 as C2 low corrosivity.
Surface Preparation & Commentsl Abrasive blast clean to Sa2½ (ISO 8501-1:1988) or SSPC-SP6 (SSPC-SP10 for optimum performance).
If oxidation has occurred between blasting and application, 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.
l Where environmental legislation dictates that strict VOC limits are adhered to it is possible to interchange relevant products for the HS (high solids) equivalents. Full details of HS products are avaialble on request from International.
l Interfine 629HS can be used in lieu of the current topcoat for interior exposures, and/or the need for an Isocynate free coating exists.
