OPE-108 (Octylphenol Polyoxyethylene Ether) is a comprehensive non-ionic surfactant with excellent emulsifying, wetting, dispersing capabilities and outstanding chemical stability as its core features. It is widely used in multiple industrial fields such as coatings, plastics, adhesives, and composite materials.

Detailed Description

OPE-108 (CAS: 121809-82-3) belongs to the octylphenol polyoxyethylene ether class of non-ionic surfactants. It appears as a colorless to light yellow transparent liquid. The polyoxyethylene ether segment in its molecular structure endows the product with excellent hydrophilic-lipophilic balance, enabling it to exert outstanding surface activity in various media systems. This product is positioned as a multi-functional industrial additive in the product line of Hai'an County Guoli Chemical Co., Ltd., suitable for multiple fields such as coatings and inks, plastics and rubber, adhesives, composite materials, and polishing care products.

The core functional advantages of OPE-108 are reflected in four aspects: First, outstanding emulsifying and dispersing capabilities, effectively reducing interfacial tension to form a stable dispersion state between incompatible liquids or solid-liquid systems; Second, strong chemical stability, maintaining performance stability under acidic, alkaline and hard water conditions, which is particularly important in harsh industrial environments; Third, low foaming tendency, reducing foam interference in practical applications for easier operation and good compatibility with various additive systems; Fourth, improved fluidity and surface effects, significantly enhancing the surface quality and processing performance of final products.

Special attention must be paid: OPE-108 is classified as Skin Corrosion/Irritation Category 1B, can cause severe skin burns and eye damage, and is acutely toxic to aquatic life. When handling, it is mandatory to wear protective gloves, goggles and protective clothing, ensure use in a well-ventilated environment, and properly dispose of waste.

Application Suggestions

The specific functions and recommended uses of OPE-108 in different fields are as follows:

  • Coatings and Inks: Used as abrasion resistance agent, anti-scratch additive and anti-settling agent to enhance surface hardness and smooth feel, improve pigment dispersion and system storage stability.
  • Plastics and Rubber Processing: As an efficient internal and external lubricant, optimize processing fluidity and mold release performance of PVC, polyolefins, etc.; used as pigment dispersant in masterbatch to improve color uniformity.
  • Adhesives and Hot Melt Adhesives: Adjust the open time, melt viscosity and heat resistance of the system, improving the application window and bonding reliability.
  • Composite Materials and Fiber Treatment: Suitable for reinforcing materials such as glass fiber and carbon fiber, used as wetting agent and surface treatment additive to improve the interfacial bonding strength between fiber and resin matrix.
  • Polishing and Care Products: Used in polishing wax, car care and floor care formulations to impart good spreadability and cleaning power, forming a high-gloss protective layer.
  • Printing Inks: Improve the rub resistance and anti-blocking property of printed surfaces, prevent blocking when stacking printed materials, and ensure pattern clarity.

Precautions

Safety Risks: This product is classified as Skin Corrosion/Irritation Category 1B (H314 causes severe skin burns and eye damage), Serious Eye Damage Category 1 (H318 causes serious eye damage), and is extremely toxic to aquatic life (H400). When handling, wear corrosion-resistant chemical protective gloves, protective clothing, safety goggles/face shield, and use in a well-ventilated area. Storage temperature should be kept not exceeding 25°C, avoid direct sunlight, and store separately from incompatible substances such as strong oxidizers and strong alkalis. In case of skin contact, immediately flush with plenty of running water for at least 15 minutes; in case of eye contact, rinse thoroughly and seek medical attention promptly. Waste disposal should follow hazardous waste management regulations; do not discharge into drains, soil or water bodies.
