Solvay Rhodoline OTE 600 Open Time Extender Surfactant

Solvay Rhodoline OTE 600 is a nonionic surfactant from the Rhodoline series, specifically engineered as an open-time extender for waterborne coatings and inks. It enhances workability by delaying surface drying without compromising film formation, adhesion, or gloss. Compatible with acrylics, vinyl acetates, and styrene-acrylic dispersions, it improves leveling and reduces edge pull. Widely used in architectural paints and industrial coatings where extended application windows are critical.

Features Of Solvay Rhodoline OTE 600 Open Time Extender Surfactant

  1. Extends open time and improves workability of water-based coatings and inks without compromising film formation.

  2. Non-ionic surfactant with low foaming characteristics, enabling stable formulation performance in high-shear processes.

  3. Enhances substrate wetting and leveling on low-energy surfaces such as polyolefins and treated plastics.

  4. Compatible with a broad range of acrylic, vinyl acetate, and styrene-butadiene polymer systems.

  5. Free of alkylphenol ethoxylates (APEOs) and meets major global regulatory requirements for sustainable formulations.

Typical Applications Of Solvay Rhodoline OTE 600 Open Time Extender Surfactant

  1. Architectural waterborne interior and exterior paints.

  2. Industrial maintenance coatings for metal and plastic substrates.

  3. Water-based flexographic and gravure printing inks.

  4. Adhesives and sealants requiring extended tack time and improved substrate adhesion.

  5. Wood finishes and clear coats where controlled drying and defect-free film appearance are critical.
