1

Rheological additives are key ingredients in paints, coatings and inks. They help control the:
a) level of gloss
b) coating application
c) final appearance
d) both b and c

Correct!

Rheological additives help to control the coating application and the final appearance.

Good try but that isn't quite right.

Rheological additives help to control the coating application and the final appearance.

2

True or False? The word "Rheology" is derived from the Greek language and refers to the viscosity of a substance being constant at different shear rates.

Nice catch!

The term "Rheology" does come from the Greek language but it actually means the study of deformation and flow of substances.

Nope!

The term "Rheology" does come from the Greek language, but it actually refers to the study of deformation and flow of substances.

3

True or False: Rheological additives are modifiers that allow formulators to adjust flow behaviors in paints and coatings.

Yep that's it!

With the modifiers painters benefit from improved viscosity and application characteristics.

If at first you don't succeed...

The modifiers allow formulators to adjust flow behaviours in paints and coatings, resulting in improved viscosity and application characteristics.

4

One of the tools used to measure rheological effects is called:
a) Newtonian viscometer
b) Rheometer
c) Brookfield viscometer

You nailed it!

Both the Rheometer and the Brookfield viscometer are used to measure rheological effects.

Please play again.

Newtonian is a type of Rheology profile. Both the Rheometer and the Brookfield viscometer are used to measure rheological effects.

5

Typical challenges customers encounter while formulating paints include:
a) Spattering characteristics
b) Brush Drag
c) Anti-settling
d) None of the above

Right on the money!

Other challenges can also include leveling and sagging.

Sorry that's not quite it.

Challenges with formulating paints include spattering characteristics, brush drag, anti-settling, leveling and sagging.

6

True or False: In coatings technology, rheology modifiers are mainly used to provide either pseudoplastic or thixotropic properties.

Niiiiiice!

You are well versed in coatings technology.

Sorry.

Rheology modifiers are mainly used to provide either pseudoplastic or thixotropic properties.
