What type of resistance does alkyd paint have when formulated properly?

The correct choice, water resistance, highlights an essential characteristic of properly formulated alkyd paint. Alkyd paints are synthetic paints derived from modified oils and resins, which endow them with specific properties beneficial for various applications. When alkyd paint is properly formulated, it creates a hydrophobic surface that repels water. This feature makes it ideal for both indoor and outdoor applications, as it helps protect surfaces from moisture-related damage, such as peeling, blistering, or corrosion.

Water resistance is particularly important in environments subjected to high humidity or direct exposure to water. It allows for easier cleaning and maintenance of painted surfaces while ensuring enhanced durability over time. Other types of resistance, such as heat or acid resistance, although important, are not primary characteristics associated with alkyd paints. Mildew resistance, while relevant to some degree, particularly in high-moisture environments, is less about the material formulation and more about the presence of biocides or additives in the paint.
