Features Of KS Chemical Rheoflow ADH-630 Adhesion Promoter

  1. Enhances interfacial adhesion between dissimilar substrates—including metals, plastics, and composites—without requiring surface etching or plasma treatment.

  2. Compatible with solvent-based, waterborne, and high-solids coating systems, enabling broad formulation flexibility.

  3. Provides excellent hydrolytic stability and long-term durability under thermal cycling and humidity exposure.

  4. Low-volatility liquid form ensures safe handling and reduced VOC contribution in compliant formulations.

  5. Enables improved wetting and substrate coverage on low-energy surfaces such as polyolefins and fluoropolymers.

Typical Applications Of KS Chemical Rheoflow ADH-630 Adhesion Promoter

  1. Aerospace structural adhesives and primer systems for aluminum-to-composite bonding.

  2. Automotive exterior trim coatings and plastic bumper primers.

  3. Industrial maintenance coatings for corrosion protection on galvanized steel and stainless substrates.

  4. Electronics encapsulants and conformal coatings requiring reliable dielectric adhesion to PCB substrates.

  5. Architectural metal cladding systems where thermal expansion mismatch demands robust interlayer adhesion.
