III. Application Areas
- Relief printing / Intaglio printing, brush application, roller application, airless spraying, compressed-air spraying ；
- Flexographic printing, wood coatings, furniture coatings, and leather coatings based on polyurethane and acrylic emulsion systems. ；
IV. How to Use
Y -233 Suitable for grinding systems; when used in clearcoats or in the later stages of the process, it should be applied under high shear or after pre‑dilution. It exhibits strong defoaming performance in high‑viscosity formulations and during the earlier stages of the process.
This product is composed of a polyether‑modified organosilicone copolymer and nano‑silica. After prolonged storage, a small amount of silica may settle; thorough mixing will not affect product performance. If the product is left standing for an extended period or stored at low temperatures, its viscosity may increase—this is a normal phenomenon. We recommend stirring well before use to ensure optimal application.
V. Packaging and Storage
This product uses 25L Plastic bucket or 200L Plastic bucket packaging, or custom-made according to customer requirements. Please… 5~35 Store under ℃ conditions and avoid direct heating. In the event of ignition or combustion, extinguish the fire using standard procedures for petroleum products. 。
In 5 ~3 5 °C At room temperature, under unopened packaging conditions, the shelf life is from the date of manufacture. 6 months.

III. Applications
- Relief/ intaglio printing, brushing, roll coating, airless spraying, and air spraying;
- Flexographic printing, wood coatings, furniture coatings, and leather coatings based on polyurethane and acrylic emulsion systems.
Ⅳ. How to Use
Y-233 is suitable for grinding systems. When used in varnishes or in downstream processes, high shear or pre-dilution is required. It exhibits strong defoaming performance in high-viscosity formulations and upstream processes.
This product is composed of polyether-modified silicone copolymer and nanosilica. After prolonged storage, a small amount of silica sedimentation may occur. A homogeneous mix will not affect product performance. It is a normal phenomenon that viscosity increases after extended storage or under low-temperature conditions. It is recommended to stir thoroughly before use to ensure proper application.
V. Packaging and Storage
This product is packaged in 25L or 200L plastic drums, or in a customized size as per customer request. Please store at 5℃~35℃ and avoid direct heating. If it catches fire and burns, put out the fire according to the general petroleum products method.
The shelf life is 6 months from the date of production at 5℃~35℃ in unopened packaging.
