Home / Abrasion & Scratch Resistance
Tougher surfaces last longer
The reason is that abrasion and scratch-resistant coatings last longer and require less frequent recoating. And, in some applications, help protect substrates from corrosion.
Benefits when using Levasil Colloidal Silica
1. Improved abrasion, scratch and corrosion resistance
2. Safe handling
3. Easy to use
How it works ?
Coating formulations made with colloidal silica help surfaces resist abrasions and scratches in two principal ways:
1. Colloidal silica increases the cross-linking density of reactive groups in organic resins thanks to its high number of hydroxyl surface groups.
2. Colloidal silica particles are very hard (5.5 on the Mohs scale of mineral hardness) and significantly improve coating hardness.
