5 Then slowly sift in the zinc filler under agitation. Power mix Part Bseparately and add slowly to the mixture. Pour mixture through a 30 mesh screen. DO NOT MIXPARTIAL : Sifting zinc through a window screen will aid in mixing process by breaking up or catching dryzinc lumps. ThinningNormally not required but may be thinned up to 15% with Thinner # 2 or Thinner # 76. In hot orwindy conditions, may be thinned up to 15% with Thinner # 33. Use of thinners other than thosesupplied by Carboline may adversely affect product performance and void product warranty,whether expressed or implied.

8 This product simply requires the substratetemperature to be above the dew point. Condensation due to substrate temperatures below the dew point can cause flash rustingon prepared steel and interfere with proper adhesion to the substrate. Special application techniques may be required above orbelow normal application conditions which are as follows: material 16 C to 29 C, surface and ambient 16 C to 32 C and humidity0% to 90%.CURING SCHEDULE Surface to HandleDry to Recoat & Topcoatw/ other finishes2 C (36 F)8 Hours6 Hours10 C (50 F)5 Hours2 Hours24 C (75 F)2 Hours30 Minutes38 C (100 F)1 Hour30 Minutes These times are based on a 75 micron dry film thickness.

9 Higher film thickness, insufficient ventilation, or cooler temperatures willrequire longer cure times and could result in solvent entrapment and premature recoat time is unlimited. Must have a clean, dry surface free of chalk, zinc salts, etc. per typical good painting StonCor Africa Technical Service for specific information. Curing DetailsRelative Humidity: 50%CLEANUP & SAFETY CleanupUse Thinner # 2. In case of spillage, absorb and dispose of in accordance with local applicableregulations. SafetyRead and follow all caution statements on this product data sheet and on the MSDS for thisproduct.

10 Employ normal workmanlike safety precautions. Hypersensitive persons should wearprotective clothing, gloves and use protective cream on face, hands and all exposed areas. Carbozinc 859 PRODUCT DATA SHEET September 2018CZ859 Page 4 of 4 CLEANUP & SAFETY VentilationWhen used in enclosed areas, thorough air circulation must be used during and after applicationuntil the coating is cured. The ventilation system should be capable of preventing the solvent vaporconcentration from reaching the lower explosion limit for the solvents used. In addition to ensuringproper ventilation, appropriate respirators must be used by all application personnel.
