Ashland’s adhesive additives – rheology modifiers, binders and reactive diluents

With a team of technical experts, specialty additives and research capabilities, Ashland is fully prepared to provide additive solutions for a broad range of adhesive applications.

Check out these recommended rheology modifiers, binders and reactive diluents. 

Rheology modifiers
 

• klucel™ h
  • Thermoplastic polymer
  • Can be used for rheology modification or as a binder in either water-based or polar solvent-based adhesive systems
  • Soluble in cold water and polar organic solvents
  • Surface active and forms films of exceptional flexibility without the addition of plasticizers
  • Provides heat sealable, non-tacky films with excellent adhesion and cohesion
     
• natrosol™ 250h4br 
  • Cellulose ether that is a free-flowing powder
  • Readily soluble in hot or cold water resulting in shear thinning solutions
  • “B” grades are biostable and offer protection against enzymatic degradation
  • “H” grades are high Mw grades that provide high viscosity build at low concentrations
  • Useful in wallpaper, latex and plywood adhesive formulations
  • Provides thickening, water binding and lubricity
     
• aquaflow™ nls-220
  • Builds low to mid shear viscosity
  • Tin, solvent and APEO free
  • Low viscosity 
  • Efficient low shear modifier that provides good control of leveling and sag resistance
  • Better formulation stability and no adverse effect on gloss

Binders
 

• pvp k-series
  • High polarity, pseudo cationic, linear nonionic polymer
  • Free flowing powder
  • Readily soluble in water and polar organics (e.g. alcohols) to form hardened and glossy films
  • Offers excellent adhesive and cohesive properties on difficult substrates
  • Can be used in re-moistenable adhesives, glue sticks (arts and crafts), pharmaceutical tapes and more
     
• aqualon™ ec-n22
  • Unique cellulose ether with a wide range of solvent solubility and film flexibility at low temperatures
  • Used for solvent-borne adhesives and hot melts
  • Provides clear, transparent films that are water and alkali resistant
     
• klucel™ h
  • Thermoplastic polymer
  • Can be used for rheology modification or as a binder in either water-based or polar solvent-based adhesive systems
  • Soluble in cold water and polar organic solvents
  • Surface active and forms films of exceptional flexibility without the addition of plasticizers
  • Provides heat sealable, non-tacky films with excellent adhesion and cohesion

Reactive diluents
 

• v-cap™ tp
  • Lower vapor pressure
  • Reduced water solubility
  • Higher melting point (compared to v-pyrol
  • Higher contact angle of cured films and increased water resistance
  • Low volatility compared to other monofunctional diluents
     
• v-pyrol™ rc
  • Higher Tg compared to v-cap
  • Improved film hardness and tensile strength
