modifiers came urethane acrylic ones aswell, which
significantly improve the application and finish of
paints and coatings”, saysMauroMeda Junior, tech-
nical coordinator atManchester.
Urethane acrylic rheology modifiers are more cos-
tly, but they providemore benefits than acrylic and
cellulose-based ones. “These products have been
usedmostly in premiumpaints. Now, however, they
are alsobeingused in standardpaints due to thebe-
nefits theydeliver, suchasgreat levelingand finishing
properties, better paint transfer to the substrate,
highwater resistance, alkali resistance, and improved
washability. With today’s technological and process
improvements, we can make our product at more
affordable costs, and since thisproduct isn’t used so
much in Brazil, we still have a largemarket to tap,”
Meda Junior announces.
The cost-benefit ratio (price vs. demand) they provi-
de, combined with their application properties, has
beenakey factor in thechoiceof rheologymodifiers.
“As suppliers, we run a variety of tests seeking tomeet
this market requirement, focusing on it as a whole and
even tailoringourproduct to regionalmarketneeds,”says
