System 2: Amino Silicone Oils (Concentrates)
| Product Name | Viscosity (25℃, mPa.s) | Ammonia Number (%) | Appearance | Key Formulation Features |
|---|---|---|---|---|
| AF-304 | 300 | 0.42 | Viscous turbid liquid | Effective improvement to raising, napping, and softness. |
| AF-1508 | 1,500 | 0.8 | Viscous turbid liquid | High ammonia value design for maximum fabric softness. |
| AF-4504 | 4,500 | 0.4 | Viscous turbid liquid | Perfect balance of viscosity and penetrating softness. |
| AF-5003 / AFR-1003 | 5,000 / 1,000 | 0.3 | Viscous turbid liquid | Minimal influence on whiteness, color light, and color fastness. |
| AF-10001 to AF-90001 | 13,500 ~ 110,000 | 0.15 | Viscous turbid liquid | Ultra-high viscosity series providing extremely thick, oily hand feel. |

Industrial Application Scenarios
Targeted solutions matched to specific substrates and engineering pain points:
Textile Finishing (Natural & Blends)
Suitable Grades: TX 6461 E, TX 6052 E, AF Series Oils.
Function: Penetrates cellulose fibers deeply via padding, dramatically improving wash-and-wear properties, crease recovery angle, and tear strength. Diamino structures provide a highly oily and full hand feel.
Sewing Thread & Yarn Lubrication
Suitable Grades: TX 6350 E, AF Amino Oils.
Function: Significantly reduces the coefficient of friction during high-speed sewing and yarn manufacturing. Also heavily utilized as an industrial lubricant for extruded rubber parts and conveyor belts.
Synthetic Fiber Modification
Suitable Grades: TX 6251 E.
Function: Engineered specifically for nylon and pure polyester (PES) fibers. Delivers excellent surface slipperiness, rebounce, and a slight color-deepening effect with mild hydrophobicity.
Personal Care & Hydrophilic Finishes
Suitable Grades: TX 5103 E, AF-E.
Function: TX 5103 E (30% solids) is highly compatible with rinse and leave-in hair formulations. The AF-E grade breaks the standard hydrophobic nature of silicones, granting fabrics excellent hydrophilicity while maintaining softness.
Packaging & Logistics Constraints
Silicone Emulsion Series (TX)
Standard Packaging: 190 kg drums.
Storage Requirements: Must be stored in tightly closed original containers. Storage location temperature must not exceed 35°C.
Shelf Life: 12 months from the date of production.
Amino Silicone Oil Series (AF)
Standard Packaging: Available in 120 kg, 190 kg, 200 kg, or 950 kg industrial barrels.
Storage Requirements: Original sealed containers, temperatures strictly controlled between 0~30°C in a ventilated environment.
Shelf Life: 18 months effective life (usable after passing follow-up inspection).
What is the recommended dosage and application method?
For the padding process, MESIL® TX emulsions are generally recommended at 5 – 30 g/L, maintaining a liquor pick-up of 50% and drying at 130°C. For the exhaust method, TX 5103 E is the only recommended emulsion, applied at 13% relative to goods weight at 40~50°C for 15-20 minutes (liquor pH ≤ 5). When formulating microemulsions from AF series amino oils, the standard silicone-to-fabric weight ratio is 0.5% to 0.7%.
Frequently Asked Questions
+How compatible are these emulsions in aqueous formulation systems?
Excellent. Grades like TX 6461 E and TX 6350 E utilize non-ionic emulsification systems, meaning they will not form complexes with anionic or cationic surfactants. TX 6350 E maintains superior dilution stability even at 2% concentrations in water.
+What is the correct mixing sequence if my formulation includes crosslinkers or resins?
As a general rule for processing polysiloxanes: If utilized alongside crosslinking agents or polyacrylate fillers, the silicone emulsion must be added in dilute form as the final ingredient. Avoid high shear forces in the finishing liquor to prevent instability and demulsification.
