Odorants or perfumes mask or reduce the undesirable odors of raw materials, solvents, or curing by-products within the coating, improving the user experience during application and after drying. Key features include a pleasant scent profile, stability within the coating matrix, and low impact on coating performance. They are suitable for architectural paints, decorative coatings, and consumer-focused products where a more agreeable smell is desired to enhance market appeal and user comfort.
A trend is the development of more sophisticated and longer-lasting fragrance technologies for coatings, as well as the use of "neutralizing" odorants that chemically bind and eliminate malodors rather than just masking them.
