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 compatible paint | We recommend that this paint is used in company with following products: VICHSILICONAL4040If you want to know other kinds of compatible coating, please consult the technical services division in Wuhan Gelin Coating Limited Company.

Storage | 25℃(77℉) | 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. | |||||||||||
