By Technology:

The technology segment is categorized water-based, oil-based, and solvent-based.

Trends in Technology:

• Inclination towards water-based coatings due to environmental regulations and consumer preferences support the adoption of effective water-based defoamers.
• Focus on bio-based defoamers derived from renewable resources to address sustainability concerns.

The water-based segment accounted for the largest defoaming coating additives market share in 2024 and is expected to grow at the fastest CAGR over the forecast period.

• Water-based defoamers represent a crucial and expanding segment within the defoaming additives market. These specialized chemical formulations utilize water as their primary carrier.
• The advantages of water-based defoamers are numerous. Their low VOC content makes them an environmentally-fervency choice compared to solvent-based alternatives.
• Increasingly stringent environmental regulations are influencing manufacturers to transition to water-based coatings, consequently driving requirement for compatible defoamers.
• For instance, in 2024, Axalta Building Products launched Cerulean, its latest generation of waterborne industrial wood coatings. This meets the needs of customers to improve environmental profiles, including the use of low-VOC products. The development of such waterborne coatings supports the adoption of water-based defoamers.
• Owing to the above-mentioned analysis, the water-based segment holds a dominant position and is growing at the fastest rate in the overall defoaming coating additives market demand.

By Application:

Based on application, the market is categorized into architectural coating, automotive coating, wood & furniture coating, industrial coating, and others.

Trends in the Application:

• There is growing trend of architectural coatings with high durability, that withstand various weather conditions and maintain their appearance over time.
• The automotive sector is increasingly focusing on lightweighting to improve fuel efficiency. This trend is driving the development of defoamers that are compatible with lightweight coating materials.  

The architectural coating segment accounted for the largest market share of 37.89% in 2024.

• Architectural coating represents the largest application segment within the market
• These coatings encompass a wide range of products, including interior and exterior paints, primers, and varnishes, all of which require defoaming additives to ensure smooth application and appropriate finish.
• Need for architectural coatings is driven by construction activity, with rise in residential and commercial building directly impacting consumption. Rise in renovation and remodeling projects also contribute significantly.
• For instance, according to the Renovation Nation Report provided by Money Co UK, it is stated that over 77% of UK homeowners spent money on changing or improving their properties in 2021. The average UK homeowner spent an average of USD 1,593.19 on home renovations.
• Increasing consumer and business requirement for durable coatings in renovation and remodeling projects necessitates performance-enhancing additives such as defoamers, boosting market growth.
• This analysis positions the architectural coating as a application segment within the dynamic demand for defoaming additives.

The industrial coating segment is expected to grow at the fastest CAGR in forecast years.
