COLLONIL NanoPro Waterproofing Spray for Leathers (300 ml)

Thanks to a combination of nanoparticles with a CFC-based resin (a substance with a well-known water and oil repellent effect), Collonil ® laboratories succeeded in improving its efficacy.

Applying these products does not alter treated material perspiration because particles do not form a covering layer; therefore, these article may be used also on high-tech materials.

Nanotechnology

Nanotechnologies may considerably change surface properties. 

Nanotechnology is the science of understanding and control of matter at the level of atoms and molecules: this research aims at producing materials with new properties.

Nanotechnology opens up completely new application areas: surface property may be definitely affected. For example, as regards automotive industry, nanoparticles make varnish more resistant to scratches; they reinforce materials in optical lenses and concerning leather production stain-resistant properties are strengthened.

''Roll-off'' effect

Nanostructured surfaces characteristics and superficial tension of water or oils prevent the infiltration in treated materials;

Leaves of certain plants and wings of insects remain clean of any oil and water owing to their surface property and nanostructure.

During “roll-off” effect attraction strength between surfaces and water is reduced: small “tips” on the surface prevent the drop to leak into the material underneath. The drop, consisting of a set of bigger molecules, slips on the very small extremities of nanoparticles. 

Leather treatment

Waterproofing with COLLONIL ® products which use nanotechnologies

According to Collonil® shoe and leather surface treatment is a fundamental application area: it allows waterproofing and increase of dirt-resistance.

All kinds of leather and fabric may be excellently waterproofed with these products.
