Lead Drier

Whatsapp Order

Lead Drier is a chemical additive primarily used in the coatings and paints industry to accelerate the drying and curing process of oil-based paints, varnishes, and coatings. It functions as a catalytic agent that promotes the oxidative polymerization of drying oils, reducing the drying time and improving the film formation. Lead driers are traditionally lead-based salts such as lead naphthenate or lead octoate, valued for their effectiveness at low concentrations. Due to toxicity concerns, their use is increasingly regulated and often replaced by safer alternatives.

Lead Drier

Primary Uses

Paints and Coatings Industry

Accelerates drying of alkyd and oil-based paints and varnishes to improve productivity.
Enhances hardness and durability of the dried paint film by promoting even curing.
Used in primers, enamels, and industrial coatings to reduce tackiness and improve surface finish.

Printing Inks

Acts as a drying agent in certain ink formulations to reduce drying time and prevent smudging.

Wood Finishing

Speeds up drying of wood stains and varnishes, aiding in quicker processing and handling.

Secondary Uses

Artist Paints

Sometimes used in oil paints by artists to control drying times and improve workability.

Adhesives and Sealants

Incorporated into some solvent-based adhesives to hasten cure and set times.

Industrial Applications

Used as a catalyst in some polymer and resin curing processes where drying speed is critical.
