Water-based silicone release agents, as eco-friendly surface treatment materials, are widely used in industries such as label and tape manufacturing, food packaging, and composite material molding due to their low volatile organic compound (VOC) emissions, non-toxicity, and safety. This paper comprehensively explores the chemical composition, physical properties, and application advantages of water-based silicone release agents, while analyzing current market conditions and future development trends. Research indicates that with increasingly stringent environmental regulations and the global push for green manufacturing, water-based silicone release agents are gradually replacing traditional solvent-based products and becoming the industry standard.

As global environmental awareness grows and governments impose stricter limits on VOC emissions, traditional solvent-based silicone release agents face significant challenges. In contrast, water-based silicone release agents, which use water as a dispersion medium, offer advantages such as low toxicity, reduced pollution, and ease of operation, making them a critical direction for industry transformation. This paper systematically analyzes the chemical characteristics, application cases, and market prospects of water-based silicone release agents, aiming to provide insights for technical R&D and market decision-making in related industries.
The core components of water-based silicone release agents typically include:
Polydimethylsiloxane (PDMS): Provides excellent release performance and heat resistance.
Crosslinkers (e.g., hydrosilylation catalysts): Promote crosslinking and curing of silicone chains.
Emulsifiers: Ensure stable dispersion of silicone in aqueous phases.
Additives (e.g., leveling agents, wetting agents): Optimize coating performance and film formation.
Low VOC Emissions: Water as a solvent minimizes harmful gas release, complying with regulations such as EU REACH and China’s GB 38507-2020.
High Stability: Optimized emulsification processes enable long-term storage without phase separation.
Broad Substrate Compatibility: Suitable for PET films, paper, PE/PP plastics, and more.
Rapid Curing: Some advanced formulations cure quickly at 80–120°C, enhancing production efficiency.
| Property | Water-Based Silicone Release Agents | Solvent-Based Silicone Release Agents |
|---|---|---|
| VOC Content | Extremely low (<50 g/L) | High (>300 g/L) |
| Environmental Compliance | Excellent (RoHS/REACH compliant) | Poor (requires special disposal) |
| Safety | Non-flammable, low toxicity | Flammable, requires explosion-proof measures |
| Cost | Lower (water replaces solvents) | Higher (solvent costs + disposal fees) |
Pressure-Sensitive Labels: Ensure easy release from silicone-coated paper/films without compromising adhesive performance.
Protective Films and Double-Sided Tapes: Deliver consistent release force to avoid residue or excessive adhesion.
Baking Paper and Non-Stick Packaging: Comply with FDA and EU 10/2011 standards for food contact safety.
Anti-Stick Coatings for Disposable Tableware: Improve food release performance and reduce grease penetration.
Rubber/Silicone Product Demolding: Used in automotive seals and electronic potting compounds.
Fiber-Reinforced Plastic (FRP) Molding: Minimize mold contamination and extend service life.
Global Market Size: Approximately 1.8 billion in 2023, projected to reach1.8billionin2023,projectedtoreach2.8 billion by 2028 (CAGR 7.5%).
Key Regions: Asia-Pacific (China, Japan, South Korea) accounts for 45%, Europe (Germany, Italy) for 30%.
Growth Drivers:
Environmental policies (e.g., China’s "Dual Carbon" goals, EU Green Deal).
Rising demand from packaging and electronics sectors (e.g., flexible display module release films).
Storage Stability: Potential sedimentation during long-term storage; requires optimized emulsification systems.
Curing Efficiency: Some products still rely on high-temperature curing, increasing energy consumption.
Substrate Compatibility: Wetting issues on low-surface-energy plastics (e.g., PP/PE).
UV-Curable Water-Based Release Agents: Reduce energy consumption and enhance production efficiency.
Bio-Based Silicone Materials: Utilize renewable feedstocks to decrease reliance on petroleum.
Multifunctional Composite Release Agents: Integrate additional features like antistatic or antimicrobial properties.
Water-based silicone release agents, with their environmental benefits, safety, and efficiency, are steadily replacing solvent-based products and becoming the mainstream choice in the release agent market. Future advancements in UV curing, bio-based materials, and multifunctional formulations will further expand their applications. Enterprises should increase R&D investments to optimize product performance and align with evolving environmental regulations and market demands.
