Critical Issues

Know What You Are Paying For

All solids are not created equal. Some manufacturers add fillers, additives, and other non-resin components (to increase their margins), reducing the performance properties of the product. Resins build physical properties and maximize crosslinking, while fillers typically only increase volume. CMT’s products are engineered to be the best quality on the market; therefore we generally do not use fillers unless your application or custom application requires them.

All Aliphatics are Not Equal

Some products from other suppliers are labeled “Aliphatic”, but are actually only 51% aliphatic (and 49% aromatic). Since these products are not 100% Aliphatic, they are not UV stable and will deteriorate and change color over time (see image below). CMT knows that only 100% aliphatic polyureas are truly UV Stable, and we engineer our products accordingly.

Below are equivalent exposure results through the use of QUV accelerated weathering equipment. (1000 hours of accelerated weathering is roughly equivalent to 1 year of outdoor exposure.) These samples are a 50 Mil Coating deposited by a High Pressure Spray System on a metal test panel.

Both test panels were originally coated with a standard grey color (appears at the top of the panel). The exposed area is the rectangular below where the hours are written.

Crosslink Density

Coatings with NO solvents of any kind by design have the capacity of exhibiting the highest crosslink density, but will vary by formula. CMT offers 100% Solids Polyureas.

Crosslink Density is a critical issue to understand, since it is directly related to performance properties of a coating system.

Visualizing Crosslink Density:
Crosslink Density can be thought of as the number of resin molecules bonded together in a specific area. For instance, chain mail has a much higher crosslink density than a chain link fence, as pictured below.

Product Development

High performance coatings should be purchased based upon the application’s requirements. While some companies have a “one size fits all” approach to product sales, CMT knows that different problems require different solutions.

CMT listens and spends time with our customers to understand their real needs, and if appropriate, CMT develops a custom solution where no solution currently exists. CMT considers clients to be “business partners”, and not just customers.
