A novel, cobalt-free drier featuring manganese neodecanoate and an amine ligand delivers faster drying times for alkyd coatings, reducing toxicity without compromising performance.
Cobalt carboxylates are commonly used as catalysts for the oxidative crosslinking of alkyd resins, which accelerate the drying of paints, inks, and coatings. Despite their effectiveness, alternatives are increasingly sought after.
Crosslinking improves coating colorfastness, durability, and salt tolerance while maintaining flexibility. And the network of chains provides for superior wind-driven rain resistance.
The new resins have a renewable carbon content, can be formulated and used without hazardous ingredients found in most competitive products, and were developed to have efficient crosslinking with environmentally compliant carbodiimide-type crosslinkers.
In this article, we discuss the design of self-healing functionality into silicone-based protective materials to improve their ability to maintain adhesion after damage.
It is therefore important to evaluate different crosslinkers and understand their benefits and drawbacks in a given system to enable the formulation of a high-performance wood coating.
The VESTANAT EP-M range is a family of silane/urethane- hybrid crosslinkers that generates multifunctional, scratch-resistant coatings applicable on a variety of substrates.
Additives belong to a broad and diffuse category of key components in a coating formulation. The following is a brief description of many coating additives, along with some examples.
