The general principle for using OPE-105 is "mix first, then dilute." Since it is a viscous liquid at room temperature, to ensure accurate measurement and rapid dispersion, it is recommended to slightly preheat it before operation (e.g., heat in a warm water bath to 30-40°C), which reduces viscosity, improves fluidity, and facilitates drum pouring and weighing. Directly adding it to a large proportion of water with rapid stirring often allows it to self-emulsify and form a working solution.
Specific usage methods vary greatly across different industries. In textile scouring and industrial cleaning, it is usually directly compounded with alkali agents, auxiliaries, etc., to form a working solution. In pesticide formulations, it is often first mixed evenly with oil-soluble technical materials as an emulsifier, then diluted in water to form a stable emulsion. In metalworking fluids, it needs to be blended with base oil, rust inhibitors, extreme pressure additives, etc., to form a concentrate, which is then diluted with water before use.
OPE-105 has good formulation compatibility and can be compounded with anionic, cationic, and other nonionic surfactants to produce synergistic effects. However, small-scale tests must be carried out during compounding to confirm no precipitation, layering, or antagonistic effects. The general addition sequence is to first mix this product with the most difficult-to-emulsify oily components, then slowly add the water phase while maintaining uniform stirring. If the water temperature exceeds its cloud point (1% aqueous solution cloud point is 65~75°C), it will form a water-insoluble emulsion. In such cases, it should be cooled below the cloud point for use to ensure complete dissolution and optimal activity.
The following are key technical indicators that need attention in the use and formulation design of OPE-105 (data source: Guoli Chemical Product Database):
| Parameter Name | Value | Usage Guidance Significance |
|---|---|---|
| Appearance | Colorless/Light yellow viscous liquid | Can determine if the product is delaminated or deteriorated |
| Active Content | ≥ 98.0% | High effective ingredient, actual dosage should refer to formulation calculation |
| HLB Value | 13.5 | Good hydrophilicity, suitable for O/W emulsification and solubilization |
| Cloud Point (1% Aqueous Solution) | 65 ~ 75°C | Operating temperature should be below cloud point to ensure activity |
| pH (1% Aqueous Solution) | 6.0 ~ 8.0 | Moderate acidity and alkalinity, wide application range |
| Viscosity at 25℃ | 200 ~ 400 mPa·s | Preheat to reduce viscosity for easy measurement during operation |
| Foam Characteristics | Low Foaming | Suitable for spray cleaning, high-pressure cleaning, and other working conditions |
