Question 1

Is Pigment Red 170 suitable for waterborne architectural paints?

Accepted Answer

Yes. PR 170 is one of the preferred red pigments for waterborne architectural coatings thanks to its good lightfastness (6–7), clean hue, and compatibility with latex binders. It is typically supplied as a water-based flush or dry powder for dispersion in acrylic or vinyl-acrylic emulsions. A dispersant such as a polyacrylate or BYK-type additive is recommended for optimal colour development.

Question 2

What is the difference between PR 170 and PR 112 in printing inks?

Accepted Answer

PR 170 offers slightly better lightfastness and a cleaner, less yellowish red shade compared to PR 112, at a modestly higher cost. PR 112 tends to have higher opacity and is preferred for opaque publication inks. PR 170's semi-transparency makes it preferable for process colour printing where shade purity is paramount, and it is more common in packaging inks for non-food applications.
