1.3 Feature and usage:
This advanced product which is nontoxic, odorless, tasteless with the advantages of good electric conductivity and thermal conductivity, rust prevention, wear resistance, strong adhesion ability etc. It can improve the quality of coating and prevent the zinc mist produced in welding and cutting, thus improving the working environments. This product has been on the market for many years, capable of partly replacing(about 20%-50%)zinc powder, widely applied as electric conductivity paint and corrosion –preventing zinc-rich paint, being a ideal new-generation product of low price(30%-40%lower than that of zinc powder)
1.4 Recommended use:
It can be used for epoxy zinc-rich priming painting or finishing, replenishing zinc, electric welding in the manufacture of motorcar and other machines; These anticorrosive painting or finishing suitable for ocean ships,containers,and other anticorrosive building and steel structures.
1.5 Practical uses:
a. Coating: as a partial substitute of zinc powder (25% calculated as weight)
b. Welding coating: It enable single layer or multi-layer coating to have the welding performance, applicable to the painting of coating, binding agent, sealing agent etc.
c. Conducting coating: Making the coating have electric-conducting and heat-conducting performances
d.Shielding layer against electromagnetic interference as a partial replacement of nickel pigment or copper pigment shielding layer(25% calculated as weight)
e.Capable of lowering sintering temperature and promoting press-forming efficiency and increase the wet strength of non-sintering powder
1.6 Packing: in 25kg or 50kg woven bag with PE bag inner or customer’s demand
