更新时间:2019-04-26  浏览次数:


                                         Description

A two component solvent based inorganic   zinc-rich silicate primer, heat-resistant 400(752).



Properties

The coating dries quickly, is hard and   provided with excellent adhesive ability.

The coating can be solidified at low   temperature, adaptable to various climatic conditions; has very high zinc   content, acting well in cathodic   protection; and is heat resistant, capable of long-time service at 400(752).



Designed Applications

Preparable to be used together with a   variety of high-performance coatings, applicable to bridges, storage tanks,   pipelines, offshore installations and steel structure.

Suggested times of coating

Airless spraying once, dry coating   thickness as 50 microns.



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 relative humidity must be less than   85%; the temperature of base material must be over 3(37.4) above the dew point.

The working can be carried out at the air   temperature of -20(-4)~50(122).

When the temperature of base material is   over high (≥40(104)), spray gun has to be used   during working; but the temperature of base material must not exceed 60(140), and GLX-1 Thinner should be   added to prevent dry spraying. 



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.



Latter

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 30(86), GLX-1 Thinner should be added to prevent dry spraying during   working.

l           If the dry coating thickness   is below the requirement, recoating with VICHSILICATE4030 zinc   silicate anticorrosive primer is needed. Before recoating, the VICHSILICATE4030 zinc silicate anticorrosive primer should be diluted with 40%   GLX-1 Thinner, which is to increase the adhesive force between the layers of   paint film.
