The purpose of this presentation is to introduce you to low-pressure, ambient temperature spraying of polyurea and to discuss the advantages of low-pressure spray equipment. Some of the inherent advantages are equipment cost, ease of use, less over-spray, and equipment mobility. This presentation will be divided into several key areas. We will examine features and benefits, general equipment specifications, capabilities, operation of the system, typical periodic maintenance requirements and examples of available options.

The need for corrosion mitigation and repair is a perennial concern for a wide array of industries. An attractive evolution in coatings application for mitigating the effects of environmental/operational degradation is cold spray of metallic replacement layers. As cold spray technologies continue to become more commonplace, portable, low-pressure cold spray systems presents an opportunity to bring metallic repair to the field for heavily damaged or corroded assets.
People have been spraying two-component materials for decades. Some processes are very rudimentary, such as mixing by hand and brushing the material on the surface. More recent techniques would be impingement mixing the material (using air to force the materials together and then spraying the material on the surface).
With modern advances in technology and materials, application equipment for two-part protective coatings has become easier to use. The benefits of using plural-component equipment far outweigh the risks. In today’s competitive market, plural-component sprayers provide the reliability and quality necessary to get work done and also provide the profit potential to help a business stay ahead of the competition.
A recent technology has been introduced where improved mechanical durability and aesthetically pleasing finish is achieved using pre-manufactured intumescent fire protection. This paper will detail how the pre-manufactured intumescent technology will provide an attractive alternative to spray application to achieve up to 2-hour rating with simple installation techniques that result in ultra smooth, no orange peel finish. This alternative process can be used on new construction, maintenance and building retrofits with little disruption on the job site.
The spray-applied, two-component, ambient-cured polyurea, which features no VOC’s and low odor, can be applied at colder temperatures than current available coatings. This wider temperature application range extends the season for restoring outdoor concrete substrates. The technology provides quick dry times; leading to faster return-to-service and helping applicators and owners meet tight deadlines.
Spray applied polyurethane and polyurea coatings, which are based on isocyanates, are widely used in a number of markets today. Several of these applications are in the automotive industry where many of the automotive paints and other coatings in use contain isocyanates. In the last 15 years, the use of isocyanates in the application of a spray applied truck bed liner (TBL) has been growing in popularity.
The polyurea technology has been developed by Texaco chemical in the 80’s. First developed for the reaction-injection-molding (RIM), it has been adapted for spray application. The development in the spray equipment in the 90’s has enabled the commercialization of 100% solid polyurea spray elastomeric coatings.
Application and curing dynamics of paints are rarely quantified over a wide range of varying climactic conditions; yet this information is critical to the final performance of the coating. There is a growing need among raw material suppliers, formulators, and applicators to better understand the performance of products under the extreme humidity and temperature conditions experienced during application.
