Product Overview

This product is an eco-friendly soft composite silica micro-powder additive specially designed for high-performance industrial coatings. Manufactured using organic silicon modification technology and inorganic nanomaterial compounding processes, it combines environmental friendliness, flexibility, and functionality. It significantly enhances coating wear resistance, adhesion, and weather resistance while reducing VOC emissions, making it suitable for coatings in industrial anti-corrosion, automotive, construction, and flexible electronic devices.

 

Key Advantages

 

 Eco-Friendly & Non-Toxic: Lead-free, cadmium-free, halogen-free, compliant with RoHS/REACH standards, and produced with zero harmful solvent emissions.
 Enhanced Flexibility: Increases coating flexural strength by 30% and impact resistance by 50%.
 Weather & Aging Resistance: UV-resistant, salt spray-resistant (1,000 hours without peeling), extending coating service life.
 High Compatibility: Perfectly compatible with common resin systems such as epoxy, polyurethane, and acrylic.
 Low-Temperature Stability: Maintains flexibility in extreme temperatures (-40°C to 200°C) without brittleness or cracking.
