How must a two-part coating be mixed to harden properly?

A two-part coating consists of two components, typically referred to as part A and part B, which need to be mixed together to initiate a chemical reaction that leads to hardening or curing. The reason mixing part A and part B is essential is that each component contains specific compounds that, when combined, undergo a cross-linking process, transforming the liquid mixture into a solid form.

In the case of two-part coatings, failing to mix both parts would result in either no hardening at all or an incomplete curing process. Each part has its own functions and properties, and they are designed to react with each other when combined. The proper ratio and thorough mixing ensure that the available chemical reactions occur uniformly, leading to a strong, durable finish.

Thus, correct mixing of the two components is crucial for the effectiveness and performance of the coating.
