Identifying Roof Failure Points

Chemical Dynamics has several decades of experience in the determination of the causes of coating failures and the determination of probable cause of exterior coating failures. Such roof failures may include corrosion, paint peeling, color change, severe chalking, cracking and spotting of coatings and damage due to scratches.  Normally coated metal roofs will demonstrate accelerated failure rates versus building sidewalls, as exposure to the sun, wind and precipitation is more severe.

Failures may be caused by one or more of the following issues: poor cleaning and/or poor metal pretreatment, poor quality metal, paint degradation (pigment and/or resin) of either or both primer and topcoat, paint formula defect, inadequate cure of coating, painting defects, paint contamination, damage and scratches during handling and building erection, and lastly aggressive climate conditions (chemical attack or environmental issues such as acid rain or a corrosive environment).

We have provided services including failure mode analysis, building site reports, test reports, analysis, expert witness reports, recommended failure remediation, and testimony on behalf of building owners as well as for companies that supply building materials.

Automotive Paint for Aggressive Environments

Some portions of the automobile must be coated with paint that offers a variety of unique long life performance attributes including resistance to harsh chemicals such as fuels, oils and hydraulic fluid, and also offer resistance to stone chipping, road salts and moisture in a variety of forms. Lastly, such coatings must also be conductive so the build-up of static electricity does not cause volatile materials to ignite.

Since there was no such coating on the market, especially a water born coating, Chemical Dynamics developed and patented this coating for use on fuel filler tubes, fuel lines and other components of cars requiring these properties. This technology named Infinicoat was one of a handful of PACE Award finalists among several hundred contestants in recognition of the value and innovation that this product brought to the automotive industry. Infinicoat is currently used on multiple domestic model cars.

Rust Erase Product Resolves Your Rust Issues

Conventional coatings that are applied to rusty metal require several preparatory steps that include removal of rust and scale by sanding, scrapping or sand blasting, followed by surface cleaning with solvent and/or detergent and then metal treatment to provide a surface for paint bonding. Rust Erase is a revolutionary new coating that penetrates & encapsulates rust without the need for prep or sanding.

Rust erase is a single component polymeric penetrant that does not need any mixing or reduction with solvents and is applied with or without surface preparation over rusty, scaly steel or non-oxidized metal. Unlike conventional paint technologies, Rust Erase penetrates and bonds to the base metal surface, polymerizes and then adheres tenaciously to provide a long lasting protective finish and proven protection in aggressive corrosion testing- used with or without a topcoat.

Lastly, Rust Erase is patent pending as it represents a significant technological breakthrough.

Energy Efficient Window Coatings Save Thousands of Dollars

Chemical Dynamics, LLC has successfully developed coatings that offer the coated surface an ε much lower that 0.9, thus reducing heating bills. In recognition of the energy savings properties of this coating, the Department of Energy Building in Washington D.C. utilized this technology to coat their aluminum window frames.

Coatings by nature have a high emissivity. Emissivity by definition is the relative property of a material’s surface to emit energy by radiation. It is the ratio of energy radiated by a particular material to energy radiated by a black body at the same temperature. A true black body would have an ε = 1 while any real object would have ε < 1. Emissivity is a dimensionless quantity. For example, a black or white painted (ε = ~ 0.9) aluminum object will absorb infrared energy (or heat) and be heated to a much greater temperature than a material that utilizes a coated surface that has an ε lower that 0.9.
