DISPERBYK-118

108-65-6

Wetting and dispersing additive for solvent-borne systems to stabilize acidic, neutral and basic titanium dioxides, colorful inorganic pigments, transparent iron oxides, fillers and effect pigments.

Applications

Liquid Coatings

DISPERBYK-118 was specifically developed to stabilize titanium dioxide. In comparison with other additives titanium dioxide can be stabilized with acidic, basic or neutral post-treatment. Furthermore, DISPERBYK-118 is extremely well suited for use with fillers, matting agents, inorganic colored pigments, transparent iron oxides, and effect pigments. DISPERBYK-118 greatly reduces the mill base viscosity and thereby enables high filler loading of concentrates. It increases gloss and reduces haze in coating systems. DISPERBYK-118 can also be used in coating systems which are applied directly onto metal since it has no negative impact on adhesion.

Recommended Use
  • Industrial coatings
  • Wood and furniture coatings
  • Protective coatings
  • Automotive coatings

 

Printing Inks

DISPERBYK-118 is suitable for stabilizing inorganic pigments, in particular stabilizing titanium dioxidein solvent-borne printing inks. In addition, DISPERBYK-118 greatly reduces mill base viscosity.


Ambient Curing Systems

DISPERBYK-118 was specifically developed for stabilizing acidic, basic, and neutral titanium dioxides. Moreover, DISPERBYK-118 is extremely well suited for use with fillers and inorganic colored pigments. DISPERBYK-118 greatly reduces the mill base viscosity and thereby allows increased filler loading. DISPERBYK-118 cannot be used in cobalt-accelerated systems because it prevents curing. It is therefore recommended for epoxy and polyurethane systems.

 

Adhesives & Sealants

The additive improves the wetting and dispersing of all inorganic fillers such as calcium carbonate and aluminum hydroxide (ATH). DISPERBYK-118 is all-purpose for titanium dioxides. The additive causes lower viscosity and enables higher filler loading.
