Tectyl 4033

Tectyl 4033 Self-Healing, Non-Flammable, Water-Based & Water-Displacing Black Underbody Corrosion Preventive Wax Coating Free of Hazardous Air Pollutants

Tectyl 4033 is a premium, water-based, thixotropic black corrosion preventive underbody wax designed to provide exceptional levels of corrosion protection and weathering for a variety of automotive underbody surfaces and industrial applications.
This premium water-based underbody coating is recommended ideally for use in the transportation industry as an undercoating for metal and wood surfaces, compatible with both new and used transportation equipment such as automobiles, trailers, last mile cargo trucks, and delivery vans.

When subjected to minor damage, Tectyl 4033’s waxy and non-tacky cured dry film can heal itself, displaying increased longevity and performance through the powerful water-resistant capabilities of its wax-like film when compared to asphalt-based coatings, being completely impervious to moisture-based corrosion 90 minutes after application.
This high quality, black corrosion inhibiting underbody coating can be applied over top previously coated surfaces and demonstrates excellent adhesion to numerous wood, metal, and plastic materials typically found on various transportation equipment.

This non-flammable, water-repelling underbody wax is formulated with an extremely low Volatile Organic Compound/Content (VOC) of just 0.6 lbs. per gallon and is completely free of Hazardous Air Pollutants (HAPs) making it suitable for numerous workplace applications.
Tectyl 4033 is a superior black corrosion preventive wax film designed to supply automotive underbodies with maximized corrosion prevention through intense water displacement, self-healing capabilities, and an environmentally friendly formulation.
