Advantages:  Surfaces primed with primer can be welded. The thickness of the coating should not exceed 10 microns.

 

It has been designed to ensure that it can be used in various climatic conditions.

 

A small amount of orthophosphoric acid

 

Surface preparation  , GOST 9.402 or STB ISO 12944-4.

 

Oil, grease, paint, dirt and other substances, such as mineral contaminants, water-soluble salts, It is necessary to remove incisions, burrs, welding spatters, round sharp edges, teeth and welding seams. Dust-free, dust-free, cleaned with sandpaper (according to GOST 6456 is allowed), degreased with white spirit (GOST 3134) or gasoline ( THAT RB 100006485.148), and it is not necessary to reduce the amount of fluxes, alkaline slags and oxides formed during welding.

 

It is recommended to improve the protective properties of the surface oxides 1 – 2 according to GOST 9.402. It is recommended to apply the primer no longer than 6 hours after surface preparation.

 

It is not recommended to use acidic converters before applying the primer.

 

The color of water should not be below 3 ° C.

 

Application:  Before use, spraying or by brush. It can be diluted with the solvent (GOST 10214 or GOST 1928) and it can be used in a 1: 1 ratio by 40% by weight of undiluted primer, filtered through mesh No. 01H – 02N (GOST 6613) and applied by pneumatic spraying. For small areas.

 

The conditions of the environment, the environment, the temperature, the environment, the temperature, the temperature,

 

It has been kept in place for a minimum of 24 hours.

 

The primer is applied to the previously prepared surface of the product in one layer and dried for 60 minutes at a temperature of (20 ± 2) ° C. The dried thickness of the single-layer coating – 20 – 25 microns.

 

Theoretical consumption of of The a  primer for a single of layer-coating is 80 – 100 g / m2.

 

The Measures Security:  for When painting The Carrying out works, as with the a well as with the the after Their completion, IT is Necessary to Thoroughly Ventilate the room. Personal protection equipment (clothing, goggles and rubber gloves).

 

Storage:  Directly closed container, protected from direct sunlight. Keep away from fire. The primer is transported and stored at a temperature of 5 – 25 ° C.
