When you add Levasil Colloidal Silica to waterborne wood coatings such as clear lacquer, it improves the mechanical properties of the coating. This results in wood coatings that are easier to apply, adhere better, and last longer. And as an end result wood surfaces that are harder and smoother and keep their rich luster naturally.

Colloidal silica enhances both open-time and the penetration of wood coatings, for better appearance and easier application. In fact, our Levasil Colloidal Silica products will give waterborne wood coatings that desirable “solventborne look” – so-called “anfeuerung”.

When added to wood coatings, colloidal silica creates a silica skeleton that improves mechanical properties. The coatings become smoother and more durable – scratch-resistant –, and their wetting abilities are enhanced. This ensures an even application as well as good overcoatability properties. 

The hard, glass-like nature of colloidal silica particles also enhanced the anti-blocking properties of waterborne wood coatings. This makes sanding between the application of different layers of coating much easier.
