POWDER MIXTURE for thermodiffusion zinc coatings TEDIZIN 

ТU 721 - 024 - 12288779 - 2006



POWDER MIXTURE for thermodiffusion zinc coatings TEDIZIN is designed for zinc coating (Sherardizing) to protect fastening and other goods from carbon and low-carbon steel, and cast iron.


POWDER MIXTURE consists of:

- component А – a inert filler packaged in polypropylene bags; shipping weight is 50 kg;

- component В – a zinc powder packaged metal cans; shipping weight is 25 kg;

- component С – a activating composition packaged metal cans; shipping weight is 15 kg.


State Registration Certificate No. 66.01.40.172.П.004365.12.02 / 27 December, 2007.


Component А is an inert refractory material applied in 10 - 15 production cycles (depending on surface preparation of goods) after coating quality decreases it should be utilized with no restrictions. Component В (zinc powder) and component С (activator) are additives in every production cycle and their quantity depends on surface square and dry film thickness, they have been used completely during one cycle.

The quantity of component B per goods quantity деталей is calculated by the equation:


mZn = 7 * F * m * d,

mZn –quantity of component B (zinc powder) (g);

F – specific surface area of goods (m2/g);

m – goods quantity (kg);

d – dry thermodeffusion film thickness (micron).


If a specific surface area of goods is unknown that quantity of component B is taken to be 0.4-0.8 g per 1 kg of goods to get 1 micron film thickness, then quantity of component B is corrected depending on achieved film thickness. At the average, to achieve 1 micron film thickness on 1 m2 area it is necessary to use 7 g of the component В.

Component С is loaded as 10- 20 % by weight of component В.
