Product Description

International Intergard 345 is a two component, low VOC, high solids, fast curing epoxy primer / finish containing zinc phosphate anti-corrosive pigmentation.

Best Uses

International Intergard 345 is formulated as suitable for use as a one or two coat primer / finish coating or as an intermediate over recommended anti-corrosive primers.
Intergard 345 provides a combination of anti-corrosive barrier protection, chemical fume and spillage resistance, along with good abrasion resistance. Ideal for use in moderately corrosive environments and where fast drying/rapid recoating is desired.


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-SP6. If oxidation has occurred between blasting and application of Intergard 345, 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. A surface profile of 50-75 microns (2-3 mils) is recommended. Intergard 345 is suitable for application to blast cleaned surfaces which were initially to the above standard but have been allowed to deteriorate under good shop conditions for up to 7-10 days. The surface may deteriorate to Sa2 standard but must be free from loose powdery deposits.

Primed Surfaces
Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If the shop primer shows extensive or widely scattered breakdown overall sweep blasting may be necessary.

Concrete, Pre-Cast Blockwork etc
Intergard 345 is suitable for application to concrete. For the first coat it is recommended that Intergard 345 is thinned 10-15% by International Thinners in order to provide good penetration of the concrete substrate and act as a primer / sealer coat. Concrete should be cured for a minimum of 28 days prior to coating. The moisture content of the concrete should be below 6%. All surfaces should be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or disintegrating concrete. All poured and precast concrete must also be sweep blasted (preferred) or acid etched to remove laitence.
