Surface must be clean, dry, and in sound condition. Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion.

Iron & Steel (immersion service) Remove all oil and grease from surface by Solvent Cleaning per SSPC-SP1. Minimum surface preparation is Near White Metal Blast Cleaning per SSPC-SP10/NACE 2. Blast clean all surfaces using a sharp, angular abrasive for optimum surface profi le (1-3 mils / 25-75 microns). Remove all weld spatter and round all sharp edges. Prime any bare steel the same day as it is cleaned or before fl ash rusting occurs.

Iron & Steel (atmospheric service) Remove all oil and grease from surface by Solvent Cleaning per SSPC-SP1. Minimum surface preparation is Commercial Blast Cleaning per SSPC-SP6. For better performance, use Near White Metal Blast Cleaning per SSPC-SP10/NACE 2. Blast clean all sur-faces using a sharp, angular abrasive for optimum surface profi le (2 mils / 50 microns). Remove all weld spatter and round all sharp edges. Prime any bare steel the same day as it is cleaned or before fl ash rusting occurs.

The following is a guide. Changes in pressures and tip sizes may be needed for proper spray characteristics. Always purge spray equipment before use with listed reducer. Any reduction must be compliant with existing VOC regulations and compatible with the existing environmental and application conditions.

Reducer/Clean Up ...........Hi-Flash Naphtha, R2K5

Airless Spray (use Tefl on packings and continuous agitation) Pressure.........................2000 - 3000 psi Hose...............................3/8" ID Tip ...................................019" Filter ...............................none Reduction .......................As needed up to 5% by volume

Conventional Spray (continuous agitation required) Gun ................................Binks 95 Fluid Nozzle Air Nozzle.......................68P Atomization Pressure .....50 psi Fluid Pressure ................20 psi Reduction .......................As needed up to 5% by volume

Keep pressure pot at level of applicator to avoid blocking of fl uid line due to weight of material. Blow back coating in fl uid line at intermittent shutdowns, but continue agitation at pressure pot.

Brush Brush..............................Small areas only; Natural Bristle Reduction .......................Not recommended

If specifi c application equipment is not listed above, equivalent equipment may be substituted.

Surface preparation must be completed as indicated.

Mix contents of Part B thoroughly with low speed power agitation.

Make certain no pigment remains on the bottom of the can. Then combine one part by volume of Part A with four parts by volume of Part B. Thoroughly agitate the mixture with power agitation. After mixing, pour through a 60 mesh screen. Allow the material to sweat-in as indicated below prior to application. Re-stir before using.

Continuous agitation of mixture during application is required, otherwise zinc dust will quickly settle out.

If reducer solvent is used, add only after both components have been thoroughly mixed, after sweat-in.

Apply paint at the recommended fi lm thickness and spreading rate as indicated below:

P T Stripe coat all crevices, welds, and sharp angles to prevent early failure in these areas.

When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle

Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profi le, roughness or po-rosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions, and excessive fi lm build.

Excessive reduction of material can aff ect fi lm build, appearance, and adhesion.

Do not apply the material beyond recommended pot life.

Do not mix previously catalyzed material with new.

In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with Hi-Flash Naphtha, R2K5.
