Description

Calcium Naphthenate is a versatile metallic soap derived from naphthenic acids, serving as a key additive and catalyst in numerous industrial processes. Its primary value lies in its ability to function as a stabilizer, drier, and gelling agent, enhancing product performance and manufacturing efficiency. This compound is essential for industries such as paints & coatings, lubricants, plastics, and construction materials, where it improves drying times, thermal stability, and material consistency.

Application

• Paint & Coating Driers: Acts as a highly effective secondary drier (through-drier) in alkyd resin-based paints, varnishes, and printing inks to accelerate the oxidative drying and hardening process.
• Lubricant & Grease Additives: Used as a thickener and stabilizer in the formulation of multi-purpose greases, providing enhanced texture, water resistance, and structural stability.
• PVC Stabilizers: Functions as a cost-effective heat stabilizer in polyvinyl chloride (PVC) and other halogenated polymers to prevent thermal degradation during processing.
• Fuel & Oil Additives: Employed as a detergent and dispersant in lubricating oils and fuels to prevent sludge formation and keep engines clean.
• Catalyst & Curing Agent: Serves as a catalyst in esterification reactions and as a curing agent for resins and synthetic rubbers.
• Waterproofing & Construction: Used in concrete sealers, asphalt modifiers, and waterproofing compounds to improve durability and moisture resistance.
• Adhesives and Sealants: Imparts improved adhesion, drying properties, and stability to various adhesive and sealant formulations.

Quality Control

Our Calcium Naphthenate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes rigorous analytical testing, including assay (calcium content), viscosity, solvent content, and acid value determination. A Certificate of Analysis (COA) documenting all critical parameters is provided with every shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent solvent evaporation and moisture absorption.
