A Low VOC and Sprayable Siloxane Nonskid/Nonslip Coating for the U.S. Navy & Non-Military Markets

A Low VOC and Sprayable Siloxane Nonskid/Nonslip Coating for the U.S. Navy & Non-Military Markets
Available for download

Qualified U.S. Navy nonskid coatings are two-component (2K) epoxy-based systems that contain various sizes of aggregate. Once mixed, these highly viscous coatings are applied using a napless roller to generate a “peak and valley” profile that provides skid/slip-resistance when cured. The roll-application process is slow and inconsistent, and appearance is often determined by experience of the applicator.

Qualified U.S. Navy nonskid coatings are two-component (2K) epoxy-based systems that contain various sizes of aggregate. Once mixed, these highly viscous coatings are applied using a napless roller to generate a “peak and valley” profile that provides skid/slip-resistance when cured. The roll-application process is slow and inconsistent, and appearance is often determined by experience of the applicator. Furthermore, these epoxy-based coating are not UV durable and quickly begin to color fade and degrade after only a short period of exterior exposure. Spray-applied versions of these coatings have demonstrated enhanced corrosion-resistance, and hence extended service-life, due to a more homogeneous surface; however, this application method has met resistance in the Fleet due to the difficulty of spraying these viscous materials and the lack of suitable commercially available spray equipment. The Naval Research Laboratory has recently developed a novel siloxane-based nonskid/nonslip coating that is exterior durable (color and profile retention), low in VOCs, lower in viscosity than epoxy-based nonskids, and can be applied using commercial pressure-pot spray equipment. NRL has also teamed with a small company to develop new spray equipment (pressure-pot and gun) that is capable of applying the siloxane nonskid with large aggregate for generating surface coefficient-of-friction (COF) values that are equivalent to those found on rolled nonskids. Spray demonstrations of the siloxane nonskid coating have been performed on Navy surface ships and submarines that operate in unique environments, yet both the coating and equipment are applicable to non-military markets where non-slip coatings are currently utilized.

A Total Performance Approach to Concrete Preparation for Epoxy Systems

Now more than ever, epoxy coatings on concrete will only prove successful if diligent care is given to the details of concrete preparation. Preparation is more than grinding or facing of an existing surface and should ideally begin in the developmental stages of the structure.

A Study of the Effect of Film Thickness and Blast Profile on Accelerated Underfilm Corrosion Creep

Product Number: 41213-779-SG

Publication Date: 2013

The creepage of corrosion underneath a coatings film applied to a steel test panel is often used as a performance test for the anti-corrosion properties of a coating system. Underfilm corrosion creep, also sometimes referred as scribe creep in the laboratory environment, is defined as the degree of corrosion emanating away from a scribe line underneath a coating film applied to a steel substrate.

A Novel Alternative Surface Preparation for Duplex Coating of Galvanized Steel

Product Number: 41213-783-SG
Author: Richard Schertzer
Publication Date: 2013
$20.00

This paper details a novel surface preparation process that is suitable for Duplex coating of galvanized steel intended for a variety of atmospheric and embedded service applications. It provides all the properties necessary for excellent coating performance and longevity, including high adhesion, excellent resistance to cathodic disbondment, and resistance to ingress of water, without the drawbacks associated with abrasive blasting, the traditional surface preparation method.
