Why have paint manufacturers like BASF, Akzo Nobel, and PPG not make a automotive roll on paint for touch up yet?

    The absence of roll-on automotive paint products from major manufacturers like BASF, Akzo Nobel, and PPG can be attributed to a few key factors:

Complexity of Automotive Paints: Automotive paints are complex formulations designed for spray application. They often consist of basecoats and clearcoats, which require precise application techniques to achieve the desired finish and durability. Roll-on application may not provide the same level of precision and uniformity.

1.    Surface Finish Quality: The quality of the finish is crucial in automotive applications. Spray painting provides a smoother, more even coat, which is challenging to achieve with a roll-on method. The texture and thickness of roll-on paint might not match the original paintwork, leading to noticeable differences.

2.    Durability and Adhesion: Automotive paints need to withstand various environmental conditions, such as UV exposure, temperature changes, and physical abrasion. The adhesion and durability of roll-on paints might not meet the standards required for automotive exteriors.

3.    Market Demand and Usage: The demand for roll-on automotive paints may be limited. Most touch-up jobs on vehicles are small and localized, making spray cans or touch-up pens more practical and cost-effective. These methods are already well-established in the market.

 4.   Technical Challenges: Developing a roll-on paint that adheres to the standards of automotive painting, including color matching, finish, and longevity, presents significant technical challenges. These factors might outweigh the perceived benefits of a roll-on product in this context.

 5.   Cost and Investment: Developing a new type of product requires significant investment in research and development, testing, and marketing. Paint manufacturers may not see a sufficient return on investment for roll-on automotive paints compared to other products.

    While roll-on paints are common in household and industrial applications, their adaptation to the specific needs and standards of automotive painting remains a challenge. Manufacturers likely prioritize products and methods that align with industry standards, customer expectations, and profitability.
