Features & Benefits
- Properties
Highest density of any extender
- Contributes to particle packing density, allowing more solids to be added to the formulation
- Exceptional noise absorption & deadening
- Excellent filler in anti-chip coatings
- Contributes to improved adhesion
Extremely low solubility
- Chemically inert
- Not affected by acids or alkalis
- Insoluble in water
- Excellent filler in corrosion resistant and flame retardant coatings
- Low reactivity with binders (extremely low magnesium & calcium oxide content)
Excellent dispersibility
- Wets easily in all systems
Good scrub resistance
- The wearing away or removal of a paint film
Improved mar resistance
- The resistance of a material to abrasive action
Neutral pH: 6.0 - 8.5
Rheology- Control of cross-linking
- Agglomeration
- Poor adhesion
- Reaction times and set times
Refractive index: 1.64 - 1.65
- One of the highest refractive indexes for a filler/supplemental pigment
- Good tint retention
- Improved hide
- Higher surface gloss
- Improved light scattering and reflectance
Titanium Dioxide (TiO2) Extender
- (ExBar® W 1) can replace as much as 6% to 14% in some formulations
Thermal stability
- Thermal degradation does not occur until 2,876°F (1,580°C) centigrade
- Excellent in heat resistant coatings
- Reduced compound stickiness
- Reduction in die swell due to increased melt temperatures in extrusion
Excellent exterior durability and weather resistance (does not chalk or yellow)
Extremely low oil absorption: 6 - 12- Low resin demand and reduction in needed binder, resulting in lower materials costs
- Higher degree of impermeability, resulting in lower resin demand
Low MoH’s hardness scale: 2.5 - 3.5
- Grinds easily
- Low abrasion
- Minimal wear on equipment
- Excellent sandability
Radiation blocking
- Blocks gamma radiation
- Does not block microwave
