FAQs
1. What are paint additives?
Paint additives are substances added to paint formulations to enhance specific properties such as adhesion, flow, leveling, and durability.
2. How do leveling agents work?
Leveling agents reduce surface tension, allowing the paint to spread evenly and create a smooth finish.
3. What are dispersing agents used for?
Dispersing agents help to evenly distribute pigments and fillers in the paint, preventing clumping and ensuring consistent color.
4. Why are defoaming agents important?
Defoaming agents prevent the formation of foam during the mixing and application process, which can lead to defects in the final coating.
5. How do epoxy curing agents function?
Epoxy curing agents initiate the chemical reaction that hardens epoxy resins, resulting in a durable and resistant coating.
