ZRC ZERO VOC PRODUCT

SPECIFICATION CRITERIA

TYPE: Two pack water based galvanizing compound.

GENERAL PROPERTIES: ZRC® ZERO VOC is a high-quality metallic zinc coating based on a trade secret binder which affords true galvanic anti-corrosion protection to metals without the necessity of sandblasting for most metals. Also withstands high temperatures.

SUBSTRATES: Apply to properly prepared carbon steel, cast iron, and aluminum surfaces. Not recommended for hot-dip galvanizing surfaces.

NOT RECOMMENDED FOR: Contact with potable water, acids or alkaline environments will require appropriate top coats.

SALT FOG EXPOSURE: 10,000 + Hours (ASTM B1I7)

PROHESION/QUV EXPOSURE: 2000 + Hours (ASTM D5894)

or if topcoat is to be applied

  

Sandblast to SSPC-SP10 (near-white cleaning) (SIS Sa 2-1/2)

High Temperature

  

Sandblast to SSPC-SP10 (near-white cleaning) (SIS Sa 2-1/2)


MIXING RATIO: 1 part Liquid: 3.1 parts Powder by weight. Containers are pre-measured to ensure proper mixing ratio. ALWAYS add powder to liquid. Homogenize thoroughly and strain through 30 mesh filter before application. To mix less than entire kit contents, weigh ingredients and use ratio printed above.

POT LIFE: 24 hours (longer times before use will result in diminished performance).

INDUCTION (SWEAT-IN) TIME: None

APPLICATION METHODS:

Recommended Procedure

Connect hose directly to
pump ensuring a hose
length of 50 ft. max. Use
in-pot agitator or
continuous recycling. Use
least pressure possible.
Start at 1500 lbs. (105 Kg/cm3)
and increase as required
for good spraying.


APPLICATION (continued):

CLEAN UP: Water

DRY TIME (set to touch): When ambient air-dried, 15 minutes @1.5 mil (38µ) thickness.

ADDITIONAL COATS: Additional coats (up to 6.0 mils total dft (152 µ) may be applied, allowing a minimum 4 hour cure time at 25ºC/ 77ºF to extend corrosion protection.

TOUCH-UP: Touch-up should be done using our ZRC Cold Galvanizing Compound, available in liquid and aerosol.

TOPCOATING: 24 hours after application of one coat of ZERO VOC (1.5 mil dft) to a sandblasted surface, ZERO VOC may be topcoated with acrylic, chlorinated rubber, epoxy, urethane or vinyl-type products. DO NOT TOPCOAT WITH ALKYD, or ALKYD-MODIFIED ACRYLIC-TYPE PRODUCTS!
