INTERGARD 345 - YELLOW (71036) - 3.03L (4:1)

Use
Suitable for use as a one or two coat primer/finish coating or as an intermediate over recommended anti-corrosiveprimers.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/rapidrecoating is desired.

Surface preparation
All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application, all surfacesshould 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 SSPC SP6 or Sa2½ (ISO 8501-1:2007). If oxidation has occurred between blasting andapplication 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.Intergard 345 is suitable for application to blast cleaned surfaces which were initially to the above standard but havebeen allowed to deteriorate under good shop conditions for up to 7-10 days. The surface may deteriorate to Sa2standard but must be free from loose powdery deposits.

Primed Surfaces
Weld seams and damaged areas should be blast cleaned to SSPC SP6 or Sa2½ (ISO 8501-1:2007).If the shop primer shows extensive or widely scattered breakdown overall sweep blasting maybe 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 thinned10-15% by International Thinners in order to provide good penetration with the concrete substrate and act as aprimer/sealer coat.
Concrete should be cured for a minimum of 28 days prior to coating. The moisture content of the concrete should bebelow 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 andprecast concrete must also be sweep blasted (preferred) or acid etched to remove laitence.

Systems recommendation
Intergard 345 is normally applied directly to blast cleaned steel, however, it can also be applied directly over thefollowing primers:
Intercure 200HS
Intercure 200
Intergard 251
Intergard 269
Intergard 345
Interzinc 52
Interzinc 315

The following topcoats are recommended:
Interfine 629HS
Intergard 740
Interthane 870
Interthane 990

Required tools
Airless spray
Recommended
Tip Range 17-21 thou (0.43-0.53 mm)Total output fluid pressure at spray tip not less than 2503 psi(176 kg/cm²)

Maximum film build in one coat is best attained by airless spray. When applying by methods other than airless spray,the required film build is unlikely to be achieved.

Air spray (Pressure pot)
Recommended
Gun DeVilbiss MBC or JGA
Air Cap 704 or 765
Fluid Tip E
Application by air spray may require a multiple cross spray patternto attain maximum film build. Lower or high temperatures may require specific application techniques to achievemaximum film build.

Brush & roller
Suitable - Small areas only
Typically 3.0-4.0 mils (75-100 microns) can be achieved
When applying Intergard 345 by brush or roller, it may be necessary to apply multiple coats to achieve the totalspecified system dry film thickness.

Drying time

Warnings

• This product will not cure adequately below 41°F (5°C). For maximum performance ambient curing temperatures should be above 50°F (10°C). 
• Surface temperature must always be a minimum of 5°F (3°C) above dew point. 
• When applying Intergard 345 in confined spaces, ensure adequate ventilation. 
• In moderately corrosive environments, it is recommended that a minimum of 4 mils (100 microns) dry film thickness should be specified to ensure adequate anti-corrosive performance. However, in non-aggressive, low corrosive environments such as those equating to C2 as per ISO 12944 part 2, it is acceptable to specify Intergard 345 as a single coat at 3.2 mils (80 microns) dry film thickness. 
• Condensation occurring during or immediately after application may result in a matte finish and an inferior film. When utilizing certain colors, particularly the darker shades via the Chromascan system where maximum addition of colorants is required, it is necessary to allow an increase in the quoted drying and overcoating times. Consult International Protective Coatings for further details. 
• Exposure to dew or rain prior to specified hard dry time may cause a deterioration in surface appearance which may in turn impair overall performance. This phenomena is particularly prominent in darker shades. In common with all epoxies, Intergard 345 will chalk and discolor on exterior exposure. However, these phenomena are not detrimental to anti-corrosive performance. 
• Where a durable cosmetic finish with good gloss and color retention is required, overcoat with recommended topcoats. 
• Note: VOC values are typical and are provided for guidance purpose only. These may be subject to variation depending on factors such as differences in color and normal manufacturing tolerances. 
• Low molecular weight reactive additives, which will form part of the film during normal ambient cure conditions, will also effect VOC values determined using EPA Method 24.
