What can result from using defective mixing ratios in two-component coatings?

Using defective mixing ratios in two-component coatings can lead to coating failures, which is a significant issue in surface finishing applications. When the components of a two-part coating, such as a resin and a hardener, are not mixed in the correct proportions, several problems can arise.

An improper ratio can prevent the coating from curing properly, which may result in a soft, tacky surface that does not achieve the hardness and durability expected from the product. This can also affect adhesion, leading to delamination or peeling of the coating from the substrate. Furthermore, a defective mix might cause issues like uneven color or finish, reduced chemical resistance, and increased susceptibility to environmental damage.

All these potential outcomes highlight why maintaining the correct mixing ratios is crucial for ensuring the performance and longevity of two-component coatings. The other options do not align with the reality of defective mixing ratios, as they suggest improvements or proper outcomes, which would not occur under such circumstances.
