Mode of action
This product is easy to dissolve, disperse and activate and it's also convenient to measure, operate and transport. It has outstanding adhesion property in the adhesion structure of rubber and brass plating, galvanized steel wire, cord or thread; It has special properties to be resistant to thermal oxidation, saline, moisture and corrosion.
Product advantages
Compared with ordinary cobalt salts, this boron-modified structure has a more durable bonding effect. Its bonding strength decreases slowly in humid and hot environments or in salt water. The particles are uniform, and they disperse well during mixing, making them less prone to agglomeration. The addition amount is small, and a small amount can significantly increase the adhesive rate of steel wires. It can improve the processing safety of the rubber compound and reduce the risk of scorching. It is compatible with natural rubber formulations and is widely used in high-end scenarios such as tire belt layers, steel wire conveyor belts, and heavy-duty seals.
Storage and guarantee period
Keep it in cool and dry place and it could be stored for one year with original package.
Packing
Carton lined with plastic bag. Net weight: 25kg/carton
FAQ
Q: What are the differences between boronate cobalt and ordinary new decanoic cobalt?
A: After boron modification, it has stronger resistance to aging and salt water, and better bonding stability over a long period of use.
Q: In which rubber products is it mainly used?
A: Radial tires, steel wire tubes, conveyor belts, metal composite rubber seals, etc.
Q: What are the storage requirements?
A: Store it in a sealed container in a cool and dry place, protected from light and moisture, away from oxidants, and avoid clumping.
