It’s hard to imagine a world without color and wollastonite has become a key ingredient in paints and coatings applications.
Our untreated extender grades and unique surface-modified wollastonite have become industry-leading additives in varied liquid and powder coatings as well as paint formulations.
Common applications using our grades include:

• Industrial and Marine
• Powder Coatings
• Architectural Coatings
• Block Fillers/Textured
• Roof and Underbody

Wollastonite is the only pure white extender that is acicular in shape. This, in combination with its unique chemistry including an alkaline pH of 9.9, offers coatings many benefits.
Our surface modified wollastonite products, WOLLASTOCOAT® pigments, are designed specially for the coatings industry. These high tech materials offer enhanced performance through barrier properties.

Benefits to using Wollastonite in the following coating applications:

Industrial and Marine

• reinforces film integrity and cohesion
• improved adhesion to metal substrates
• excellent corrosion and blister resistance
• good stability in most water-based systems
• enhances resistance to brittle failure and film degradation
• synergism with anti-corrosion inhibitors
• surface treatment improves homogeneity and engineered reactivity
• lowers film transmission properties
• reduces cracking, checking

Powder

• cost-effective gloss reduction
• increased crack and chip resistance
• enhanced colour-fastness and moisture/corrosion resistance
• superior reinforcing performance
• lower specific gravity than competing materials
• heat stable, resistant to ultra-violet degradation and chemical attack
• lowers film transmission properties

Architectural

• pH buffer – prevents downward pH drift
• burnish resistance
• improved tintability
• in-can and nail head corrosion protection
• reduced drying times
• stain blocking
• maintains wet edge
• improved color acceptance/development

Block Fillers and Textured Coatings

• improved reinforcement
• asbestos replacement
• mud crack resistance
• low water demand
• ease of application

Roof and Underbody

• key ingredient in the replacement of asbestos
• high G.E. Brightness
• improved strength and sag control
• reduced susceptibility to UV related cracking
