Dex-O-Tex Aero-Flor Coating



1.) PRODUCT DESCRIPTION

A) Composition

Dex-O-Tex Aero-Flor is a durable, chemical-resistant floor coating designed for use in aircraft hangars, service bays, manufacturing areas, etc. Aero-Flor offers good chemical resistance, excellent cleanability, and superior appearance. The material is available in a range of colors as well as clear and white. It is noticeably light reflective.

A polyurethane material, Aero-Flor is applied over an epoxy primer coat. Although quite glossy, Aero-Flor offers good traction underfoot. For additional slip-retardance, it is also available in three skid-resistant profiles.

Dex-O-Tex Aero-Flor conforms to all requirements of U.S. General Services Administration Specification A-A-50542 ("Coating System: Reflective, Skip-Resistant, Chemical-Resistant Urethane for Maintenance Facility Floors"). Aero-Flor is VOC compliant, although it does have some solvent odor during installation.

This product can be used in both interior and exterior service. Dex-O-Tex Aero-Flor possesses excellent resistance to ultraviolet light including freedom from color change or degradation.

B) Typical Uses
Dex-O-Tex Aero-Flor is used in manufacturing areas, automobile service bays, aircraft hangars, etc.
