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.
