Top 10 Companies in the One-Component Liquid Rubber Market (2026): Market Leaders Powering Global Construction and Innovation

MARKET INSIGHTS

Global one-component liquid rubber market size was valued at USD 1.76 billion in 2025 and is projected to reach USD 2.61 billion by 2034, exhibiting a CAGR of 4.5% during the forecast period.

One-component liquid rubber refers to single-component, moisture‑curing polyurethane or polymer-based systems that cure at room temperature to form a seamless, flexible, and durable rubber‑like membrane. These products are predominantly used as high-performance waterproofing sealants, coatings, and adhesives in construction, automotive assembly, and industrial manufacturing. The material’s key advantages include ease of application without mixing, excellent adhesion to diverse substrates, and resistance to weathering, chemicals, and mechanical stress.

The market is experiencing steady growth, primarily driven by robust infrastructure development and renovation activities worldwide, particularly in the Asia‑Pacific region. Stringent building codes emphasizing energy efficiency and waterproofing integrity further bolster demand. However, growth is tempered by volatility in raw material costs, especially for petrochemical-derived polyols and isocyanates. Leading companies like Sika AG and Henkel AG & Co. KGaA are actively expanding their product portfolios with sustainable, low‑VOC formulations to comply with tightening environmental regulations and capture growing market segments in green building projects.
