Product Functions

• Superior Lubrication:

H-8228’s unique structure reduces friction coefficients, providing long-lasting lubrication for mechanical components. Used in high-end cutting fluids, it extends tool lifespan, enhances machining precision, and minimizes wear.

• Surface Tension Reduction:

With ultra-low surface tension, H-8228 effectively prevents fogging. As a plastic additive, it modifies surface properties, improving light transmittance in anti-drip greenhouse films.

• Textile Enhancement:

In fabric finishing, H-8228 imparts softness and smoothness for skin-friendly textiles. It also adds anti-static properties, reduces dust adhesion, and enhances moisture absorption for superior comfort.

• Coating Performance Boost:

Acts as a leveling agent in coatings, paints, and polyurethane slurries to reduce intermolecular stress, eliminate surface defects (e.g., orange peel), and improve coating uniformity, aesthetics, and protection.

• Excellent Solubility & Compatibility:

Highly soluble in water, polar solvents, and select non-polar solvents. Ensures effortless dispersion in complex formulations and broadens application versatility.

• Demulsification:

Facilitates rapid oil-water separation in industrial processes, enhancing production efficiency and product quality.
