Red lead is a type of orange-red powder which is also known as minium. It is commonly used in rust proof paints and in manufacturing process of storage batteries. Let us go in-depth and examine other properties of red lead.
What is red lead?
Red lead, also known as Lead Tetra Oxide is a type of bright red powder that is utilized for making red pigments and lead glass. If paint has red lead then it helps in protecting steel and iron from problems such as rusting.
Chemical Properties
As per red lead suppliers in Bangalore, chemical composition of red lead makes it water insoluble. Additionally, it is prepared through oxidation of lead monoxide (litharge) or metallic lead. Moreover, commercial products by lead suppliers in India oftentimes have litharge in the form of an impurity.
Red Lead Primer
Primer consisting of red lead is considered oldest and a commonly utilized anti corrosion pigment that is applied over metal surfaces. It is able to resist salt water and as such, was the primer of choice for painting decks and hulls of ships.
Normally, steel surfaces were painted using 85% to 95% red lead to achieve better corrosion resistance.
Other Uses of Red Lead
1. Red lead provided by red lead suppliers in India finds its use as an effective curing agent in many of the polychloroprene rubber compounds.
2. It is also utilized as a replacement for magnesium oxide to offer improved water resistance.
3. Earlier, it was also utilized in engineer’s scraping, which has now been replaced by engineer’s blue.
