Formulations are sometimes adjusted by fine tuning various additives, including antioxidants and light stabilizers, which provide different thermal and light stabilization properties. It is very important to find the best combination of additives to achieve the necessary performance, especially if the final substrate or area to be powder coated requires specific durability or heat resistance.
While the surface phenomena of coatings cause coating issues, understanding surface tension modifiers and their limitations will allow coatings formulators to create more robust coatings systems.
In shipping's ongoing efforts to survive and thrive in the global economy, and on the backdrop of societal and regulatory pressure to reduce maritime's impact on the environment, tackling biofouling head-on and mitigating the risks has never been so important.
This interview with BioCote® discusses how antimicrobials work in coatings, benefits they provide, demand, classification and what the future holds for this important technology.
This second article in our four-part series about additives discusses foam control agents, including defoamers, anti-foams and air release agents (deaerators), and some things to consider to help your formulation be both efficient and persistent.
Finding a "golden ratio" of time-tested preservatives has wide-ranging benefits for formulators in the paints and coatings space, enabling customers to serve local markets and meet global standards.
Whether decorative paints or industrial coatings, waterborne finishes need a perfect surface appearance and optimal mechanical properties. Leveling and substrate wetting agents can be a valuable aid for this purpose.
The article also addresses a specific limitation (tint viscosity retention) that occurs with NISATs, and how next generation tint viscosity stabilizers help alleviate this concern.
Additives are used in small quantities and can have the highest per unit cost of coatings raw materials. They facilitate production, or improve certain properties of the wet coating or the final film. Learn about rheology modifiers and suspension agents in Part 1 of this four-part series.
