3. 🛠️ Application Guide
3.1 Recommended Application Fields
Toynol® FS-204BC surfactant is widely applicable in waterborne coatings, inks, varnishes and adhesives, fountain solution, agricultural chemicals, metalworking fluid, and passivating processes, effectively improving product performance and processing effects.
3.2 Usage Methods and Recommended Dosage
• Recommended Dosage: The optimal addition level is 0.2-2wt.%. Specific concentration should be determined by conducting a ladder study according to actual application scenarios.
• Mixing Requirement: Keep agitating for at least 15-30 minutes to ensure thorough mixing. Heat appropriately if viscosity increases.
• Addition Sequence: It is recommended to add Toynol® FS-204BC after other surfactants and polymers to ensure its dissolution or dispersion in the system. Add it before pigments, fillers, and other solid substances to facilitate wetting of solids and inhibit foam introduced by agitation.
• Low-Temperature Handling: During transportation and storage at low temperatures, the product may solidify or crystallize. Heat it to the melting point and stir to restore its original state without affecting service efficiency.
4. ⚠️ Safety and Storage
• Safe Operation: Follow standard industrial operating procedures. Avoid unnecessary contact with skin and eyes. In case of accidental contact, rinse with plenty of clean water. If discomfort persists, seek medical attention.
• Storage Conditions: Store the product in a sealed container in a dry, cool, and well-ventilated warehouse at room temperature. Keep away from fire sources and avoid direct sunlight.
• Packaging and Shelf Life: The product is available in 25L/220L drums. For other packaging requirements, please consult our sales team. The shelf life is determined according to standard storage conditions; refer to the MSDS for detailed information.
