High Performance Coatings
Best coatings for highest standards
These are highly advanced SiO² coatings which were created to address the needs of the marine, military and aerospace sectors. They are massively resistant to corrosion, abrasion and temperature. They can be applied to metal, plastic, powder coated and painted substrates. The coatings can be heat cured, or cured at ambient temperature. They react with the substrates surface and forms an abrasion resistant coating with very high bonding properties on metal. It generates thin, transparent coatings with high impact strength and is resistant to alkali, abrasion and corrosion.
