OPE-108 (Octylphenol Polyoxyethylene Ether) is a nonionic surfactant with an HLB value of approximately 13.5. It is easily soluble in water and organic solvents and serves as a functional additive in various industries such as coatings, inks, plastics, adhesives, composites, and polishing care products. Its usage method is not limited to a single fixed procedure; instead, the product is incorporated into the target system at a certain proportion, leveraging its excellent emulsifying, wetting, and dispersing capabilities to achieve process improvement. The typical operation procedure is: first, calculate the required amount of OPE-108 based on the total formulation, then slowly add it to the water phase or oil phase under stirring conditions (depending on the system type), mix evenly, and allow it to naturally integrate into the system.
Due to significant differences in formulation components and process conditions across different fields, the specific dosage needs to be optimized through small-scale tests and pilot tests. Generally, the usage amount of additives ranges from 0.1% to 5% of the total formulation. However, there is no detailed recommended value for OPE-108 within this range in the existing database. Users need to conduct gradient experiments based on the desired emulsification effect, wetting speed, or dispersion efficiency to determine the optimal proportion. Regarding temperature, note that the cloud point of its 1% aqueous solution ranges from 61 to 67°C. When heating for use, the temperature should be controlled below this range to maintain a transparent and stable solution.
The following key parameters can help you more precisely control the operating conditions during use:
| Parameter | Value | Reference Significance for Use |
|---|---|---|
| Appearance | Colorless to light yellow transparent liquid | Abnormal appearance may indicate changes in product quality |
| HLB Value | 13.5 | Favors O/W type emulsification, suitable for oil-in-water systems |
| Active Content | ≥99% | High purity, dosage calculation can be directly based on active matter |
| Cloud Point (1% aqueous solution) | 61~67°C | Avoid exceeding this temperature when heating to prevent precipitation |
| pH Value (1% aqueous solution) | 6.0~8.0 | Neutral range, minimal impact on system acidity or alkalinity |
| Surface Tension (25°C, 1%) | 29~30 mN/m | Key reference reflecting wetting and spreading ability |
| Penetration Power (0.5% solution) | ≤60 seconds (Standard canvas method) | Reflects penetration speed, reference for quick wetting applications |
| Density (20°C) | 1.06 g/cm³ | Reference for volume-to-weight conversion during weighing |
| Viscosity (25°C) | 250 mPa·s | Facilitates design of pumping and stirring operations |
| Pour Point | <-5°C | Remains flowable at low temperatures, not prone to freezing |
Based on the role requirements in various application fields from the Guoli Chemical database, typical usage methods of OPE-108 are as follows:
Safety protection must be given top priority. OPE-108 is classified as Skin Corrosion/Irritation Category 1B, Serious Eye Damage Category 1, and is hazardous to the aquatic environment (H400). Operators must wear corrosion-resistant chemical protective gloves, protective clothing, and safety goggles/face shields throughout the process and use it in a well-ventilated area. In case of skin or eye contact, immediately rinse with plenty of running water for at least 15 minutes and seek medical attention promptly. Do not discharge waste liquid or rinse water into drains or water bodies. Waste materials must be disposed of as hazardous waste by qualified units.
