Stopping Corrosion in Mine, Quarry and Aggregate Processing Structures
Although CBPC coatings are relatively new in mine, quarry and aggregate processing applications, their use will only grow as word spreads about how they can inhibit carbon steel hopper and structural corrosion for decades as well as reduce pre…
1K Hydrophobic Binders for Anticorrosion Primers and DTM Topcoats
Binders that show a high contact angle both before and after the salt spray test perform better for corrosion protection, compared to those that show low contact angles before and after the test.
Going Nano to Mimic Penetration of Solvent-Based Products
Greater awareness of phenomena that occur on a nanometric scale and subsequent testing (both in application and synthesis of polymers) have led to the development of new materials with better performance characteristics than the traditional on…
Selecting the Best Resin for Your Recipe
Kevin Biller combines his love of food and cooking with his years of knowledge in researching, developing and testing powder coatings.
The Impact of Film Properties on Corrosion Resistance
The adhesion/corrosion balance of the previous study yielded significant new insights into resin design. Polymers with good wet adhesion and good corrosion resistance could be isolated, and those properties correlated back to their monomer com…
Epoxy Resins for Semiconductor Packaging Assemblies
Semiconductor packaging assemblies require immense durability to protect the finished device from heat, physical impact, warping, static electricity and moisture. Therefore, formulators of epoxy compounds for semiconductor packaging assemblies…
Low-Viscosity Oligomers for 100%-Solids UV-Curable Soft-Touch Coatings
Newly designed low-viscosity oligomers allow the formulation of UV-curable soft-touch coatings without the need for solvent or water diluents.
How the Design of (Poly)isocyanate Hardeners Can Impact the Properties of Aliphatic Polyurea Coatings
The present study shows that the reactive diluent Tolonate X FLO 100, used in blend with conventional HDI-based polyisocyanates, can bring significant advantages to 2K polyaspartic systems.
Mechanical dispersion technology turns thermoplastic resin into sprayable coating
The metal packaging industry demands a high-performing coating with a food safety profile desirable to consumers, which not only avoids BPA, but also other materials of concern such as epoxy, styrene or phenolic crosslinkers.
