Properties

The   paint film is tenacious and abrasion resistant, provided with excellent

adhesive and impact resistant   ability;

With good oil resistant and   solvent resistant ability;

With   excellent saltfog resistant and water resistant ability;

Of extremely good anticorrosion property,   suitable for single-layer coating or to be applied as the primer in   high-performance formula. The dry coating has the high zinc content, which complies with the composition and performance   requirements of HG/T3668    in China Chemical Industry, acting well in cathodic protection.

Designed   Applications

As   the primer prepared for heavy anticorrosive coating, able to provide maximum   protection and adapts to various strongly corrosive environments. Applied to   ship equipment, bridges, petrochemical plant, power plant, etc.

Intervals   of recoating

Suggested   times of coating

Airless   spraying once, dry coating thickness as 50~70 microns, brush painting or   roller painting for 2~3 times.

Surface   Treatment

Ø   Use sand blasting till the level of Sa 2.5 to remove oxide skin   and iron rust, roughness: 40~75 microns;

Ø   Be sure to get rid of the oil stain and weld spatters on the steel   plate before rust removal, and burnish welding seams and closed angles;

Ø   For the surface coated with shop primer, oil stain, moisture, zinc   salts and dust must be removed. For the partially rusty part, adopt local   sand blasting till Sa2.5 Level for rust removal, or adopt elastic grinding   wheel buffing till St.3 Level.

Temperature   of

base   material

The   temperature of base material must be over 3℃(37.4℉) above the dew point.

When   the temperature of base material is below 5℃(41℉), the reaction of epoxy and solidifying agent becomes slow, which   is not suitable for using.

Safety   Protection

There   should be good ventilating devices provided at the work site. During working,   wear the appliances for labor protection such as gauze mask, spectacles,   gloves, etc. to avoid skin contact with and suction of solvent or paint fog.   Smoking is forbidden at the work site, and all fire sources shall be   isolated.

Precautions

l           Long-time exposure of the   zinc-rich primer will cause the formation of zinc salts (also called white   rusts) on it. On the surface with zinc salts, cleaning level sand blasting or   mechanical rust removal should be adopted for secondary surface preparation   and removal of all impurities.

l           Overthick coating will   prolong the minimum interval of coating and handling time, and may have   adverse effect on the intervals of recoating.
