End-Use Industry Insights

Paints, Coatings & Inks
The paints, coatings, and inks sector led the defoamers market in 2024 with a 21.8% share. Defoamers are indispensable in this industry, where foam formation can compromise product uniformity and aesthetic finish. As demand for high-performance and eco-friendly coatings rises, so does the need for advanced defoaming solutions that meet both performance and regulatory standards.

Water Treatment
The water treatment segment is forecast to expand at a CAGR of 5.1% from 2025 to 2030. With increasing global concerns over water quality and wastewater discharge, defoamers are being adopted to enhance process efficiency and compliance with environmental regulations. Eco-conscious formulations are also gaining favor in this segment, reflecting the market’s pivot toward sustainability. 

Product Insights

Silicone-Based Defoamers
Silicone-based defoamers accounted for the largest revenue share—37.8%—in 2024, owing to their superior thermal stability, chemical resistance, and long-lasting performance. These products are highly effective in applications such as paints, coatings, pulp and paper, and textiles, especially in challenging conditions involving high temperatures and fluctuating pH levels. Their low dosage requirements and exceptional defoaming efficiency further reinforce their market dominance.

Water-Based Defoamers
Water-based defoamers are projected to witness robust growth during the forecast period. Valued for their non-toxic, environmentally friendly profile, these defoamers are gaining traction across industries including pharmaceuticals, food processing, and water treatment. They offer strong compatibility with aqueous systems and are becoming a preferred choice in regions with strict environmental regulations.

Furthermore, the transition toward eco-friendly and biodegradable defoamers is accelerating. This shift is driven by rising consumer awareness, tightening environmental regulations, and a broader market movement toward sustainable chemical solutions. Manufacturers are increasingly investing in R&D to develop high-performance, cost-effective, and regulatory-compliant defoamers that align with both industry requirements and evolving consumer expectations.
