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: 1\Industrial and Marine 2\Powder Coatings 3\Architectural Coatings 4\Block Fillers/Textured 5\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.
Benefits to using Wollastonite in the following coating applications: Industrial and Marine 1\reinforces film integrity and cohesion 2\improved adhesion to metal substrates 3\excellent corrosion and blister resistance 4\good stability in most water-based systems 5\synergism with anti-corrosion inhibitors 6\surface treatment improves homogeneity and engineered reactivity 7\reduces cracking, checking
Powder 1\cost-effective gloss reduction 2\increased crack and chip resistance 3\superior reinforcing performance 4\lower specific gravity than competing materials 5\heat stable, resistant to ultra-violet degradation and chemical attack 6\lowers film transmission properties
Architectural 1\burnish resistance 2\improved tintability 3\in-can and nail head corrosion protection 4\reduced drying times 5\stain blocking 6\maintains wet edge 7\improved color acceptance/development
Block Fillers and Textured Coatings 1\improved reinforcement 2\asbestos replacement 3\mud crack resistance 4\low water demand Ease of application
