Auto Paint Additives​

What Are Paint Additives?

Paint additives are products added to automotive paints, primers, clear coats or other refinishing materials to modify or improve their performance during application and curing. Depending on the product, an additive can help improve flow and levelling, control drying or curing, enhance flexibility, reduce surface defects, or make a coating more suitable for particular application conditions.

Using the right paint additive can help painters achieve a smoother, more consistent finish while making the paint system easier to apply. However, additives are not suitable for every paint or coating, so always check the manufacturer's technical data sheet and recommended mixing ratios before use.

Types of Automotive Paint Additives

At Jefferson Paint Supplies, you can find a range of paint additives designed for different automotive refinishing requirements, including:

• Paint Accelerators: Help speed up the drying or curing process of compatible automotive coatings, potentially reducing waiting time between coats.
• Flex Additives: Improve the flexibility of coatings, particularly where paint is applied to flexible plastic components and other substrates that may move or flex.
• Flow & Levelling Additives: Help improve paint flow and levelling during application for a smoother, more uniform finish.
• Slow / Retarder Additives: Slow the drying rate of compatible coatings, which can help with application in certain temperatures and conditions.
• Anti-Silicone Additives: Designed for use in compatible paint systems to help address certain surface contamination and finish issues.
• Plastic Additives: Help prepare or modify compatible paint systems for application to automotive plastic components.

Always use additives according to the paint manufacturer's recommendations. Adding too much or using an incompatible additive can affect drying, adhesion, gloss, durability and the overall finish.
