更新时间:2019-04-26  浏览次数:


Description

 A fast drying, two component,   weldable inorganic zinc silicate shop primer.



Properties

The coating dries quickly, is hard and   provided with excellent adhesive ability. The coating can be solidified at   low temperature

With good oil resistance, water resistance,   age resistance, cathodic protection property   and ocean climate resistance;

The rust cycle is 6~7 months;

The coating is heat resistant, capable of long-time service at 400℃(752), of with excellent capable of flame cutting and solderability.

The content of lead and heavy metal   all are in accordance with the requirement   of environmental standards in theUnited Statesand Europe.



Designed Applications

Applicable to the temporary protection of   steel structure in offshore installations, chemical plants, petrochemical   plants power stations, bridges   etc.

Suggested times of coating

Spraying once, dry coating thickness as 15~20   microns, The   thickest part as no more than 25 microns.



Subsequent coats

Epoxy zinc   phosphate antirust paint, micaceous iron epoxy antirust paint, epoxy   intermediate coat; chlorinated rubber, polyurethane and organic silicate   finish paint.



Surface Treatment

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     Use sand blasting for surface   treatment: remove oxide skin and iron rust, with the cleanness reaching Sa   2.5 Level, roughness: 40~75 microns. If oxidation appears on the steel   product surface to be coated after sand blasting, this surface should be   treated with sand blasting again until it reaches the specified standard.

Ø     It is not recommended to use   this product on the surface on which rust removed manually.



Temperature of

base material

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

The recommended temperature of base   material is 30~40(86~104).



Usage

Mixing

The product is packed in two containers   separately that form a unit. For use every time, completely and uniformly mix   it according to the specified compounding ratio; and keep stirring during   spray painting in order to prevent zinc dust precipitation. The product must   be used up within the specified mixture pot life.

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.

6 months (Exceeding the storage life, the   product must be retested, and can be used only if passing the test.)

The product should be kept at cool and   dry place, away from heat sources and fire sources.




Precautions

l           If the temperature is above 3086℉, 5~10% GLX-1 Thinner should be added to prevent dry spraying   during working.

l           If the dry coating thickness   is below the requirement, recoating with VICHZINC1020   is needed. Before recoating, the VICHZINC1020   should be diluted with 40% GLX-1 Thinner, which is to increase the adhesive   force between the layers of paint film.
