Sticking issues on the Yankee dryer caused by ink residues, resin precipitation, and cationic starch lead to sheet breaks, reduced production efficiency, and paper defects like oil spots and stains. A poorly chosen or misapplied water-based release agent can fail to provide adequate release, leave residues, or even corrode the dryer surface.
PR-07 Water Cylinder Release Agent from Luterra Advanced Materials is a new-generation, nonionic, water-based formulation synthesized from high-end organic silicone raw materials. It delivers triple effects of lubrication, release, and gloss enhancement. This guide covers five critical mistakes to avoid when selecting and using a water-based cylinder release agent.
Mistake #1: Choosing a Release Agent That Isn't pH-Neutral and Non-Corrosive
Some release agents, especially solvent-based or acidic types, can corrode the Yankee dryer surface over time, leading to costly repairs and reduced lifespan.
PR-07 uses a neutral to weakly alkaline formulation (pH 6.0–9.0), with pH strictly controlled within a safe range. It contains no strong acids, strong alkalis, or halogen-based corrosive components, ensuring it protects your valuable Yankee dryer.
Mistake #2: Overlooking the Importance of Gloss Enhancement
In many applications, especially for high-quality papers, the release agent should do more than just release-it should also enhance the paper's surface gloss and finish.
PR-07 delivers triple effects of lubrication, release, and gloss enhancement. It leaves a smooth, high-gloss surface on the paper, improving its aesthetic and printability characteristics.
Mistake #3: Using a Product That Fails to Address the Root Cause of Sticking
Many release agents only provide a temporary barrier, without effectively tackling the underlying issues like ink residues, resin precipitation, or cationic starch buildup.
PR-07 thoroughly resolves sticking issues caused by these contaminants. Its excellent film-forming properties and heat resistance create a uniform, durable protective layer that prevents adhesion at the source.
Mistake #4: Using the Wrong Application Method for Your System
Different paper grades, machine speeds, and release difficulties require different application strategies. Spraying onto the Yankee surface versus adding to the pulp system each has its advantages.
For optimal results with PR-07:
Spray method (recommended): Use a metering pump to inject into a dilution tank, dilute with room temperature soft water, then apply evenly onto the dryer surface via a high-pressure pump. This is ideal for targeted application.
Pulp addition: Add directly into the pulp system. This provides distribution throughout the sheet.
Dosage: 0.3–1.0 kg per metric ton of dry pulp, adjusted based on basis weight, machine speed, and release difficulty.
Mistake #5: Ignoring Environmental and Safety Compliance
Some release agents contain high levels of VOCs, formaldehyde, benzene, or other hazardous substances, posing risks to workers and the environment.
PR-07 is a water-based product with extremely low VOC content (<50 g/L, well below national standards) and contains no formaldehyde, benzene, or other hazardous substances. It is safe, compliant, and aligns with modern mill sustainability requirements.
