Siloxanes & Silazanes

Based on 686 products - Last update on the Nov 4, 2025

Silicones and silazanes appear as clear to slightly hazy liquids that cure into protective, hydrophobic coatings. These materials offer excellent weatherability, chemical resistance, and durability, ensuring long-lasting protection against harsh environmental conditions. They are ideal for high-performance protective coatings, automotive clearcoats, and industrial finishes. 

Silicones and silazanes are favored for their balance of flexibility and resistance to high temperatures. The industry is advancing toward low-VOC and modified silazane formulations to enhance sustainability. Available in solvent-based and waterborne forms, they support diverse applications while complying with environmental and workplace safety regulations.
