The concept of an organic coating system consisting of a hot-melt coating (also known as thermoplastic coating), overcoated with a water-thinned coating while in the molten state, was explored by the development of solvent-free shop primers for forest product-based exterior architectural components. These shop primers with and without commercially available finishes were compared to selected commercial coating systems on various substrates by weather exposure in multiple locations. The concept is in its infancy, but coatings developed are commercially practical with performance equal or superior to conventional coating systems of recognized quality. Suggested applications of the concept include road marking and interior trim. The field is open for exploitation.
This article details a statistical design experiment that was commissioned to explore in more detail the roles and effectiveness of varying parameters (raw materials, PVC, types of steel, etc.) in producing intumescent paints.
Additives based on hyper-branched polymers with tailor- made particle-affinic groups lead to very high-performing products to be used in silica matted solvent-free UV-curing coatings.
Waterborne OMU has all the advantages of solventborne OMU including inherent mar resistance, chemical resistance and amber film color, while overcoming the shortcomings of low-VOC solventborne OMU including slow dry and softer film.
The fast cure speeds and longer pot life allow for more efficient working, saving time and overall project expenditure, while its robust curing features reduce the risk of complaints.
The safe use of a sustainable, ecological yet flammable construction material while retaining its elegance and beauty paves the way for one perfect combination classic design and the highest safety standards.
The incorporation of metallic and pearlescent pigments is a proven method to generate interest and improve viewer perception of powder coatings. Effect pigments convey a message of premium product finish with the visual association conveyed to the coated parts or products.
The consumer wants it all. The commonwealth wants what’s best for all. As scientists, we keep proving that we can meet that high standard. And the work is far from over.
Canada’s approach to chemicals management over the past decade is an evidenced-based assessment of chemicals in commerce, using the latest scientific data to determine a chemical’s risk to human health and the environment.
