Raw Materials Protect, Bind and Seal Construction and Infrastructure
Projects
From Boston Harbor's Deer Island treatment plant to Cleveland's
Rock and Roll Hall of Fame to the San Antonio River Walk, Bayer
polyurethane coating raw materials and technology are protecting
structures all across North America. Polyurethane coatings formulated
with Bayer's coating raw materials provide long-term corrosion protection
and increase the service life of exposed components of buildings,
water tanks, bridges, stadiums and more.
Typically, two-component
solventborne systems are used for basecoats, intermediate coats
and topcoats, but increasingly architects are specifying waterborne
systems. Developed by Bayer, this system dramatically reduces
volatile organic compounds (VOCs) by up to 90 percent. Bayer was
honored by the U.S. Environmental Protection Agency with the Green
Chemistry Award for creating a coating system that uses water instead
of chemical solvents, thus reducing VOCs.
Another system quickly gaining popularity is the moisture-cured
polyurethane paint system. It is capturing a growing share of
new construction projects, especially when productivity and long-term
performance are required. The moisture-cured system is able to withstand
heavy abrasion during shipping, low temperature cure (down to 20°F)
and high humidity. It also offers excellent resistance to yellowing
and chalking or degradation caused by sunlight.
A relatively new chemistry
to the construction and infrastructure markets is polyaspartic
coating technology. Polyaspartics enhance the use of conventional
two-component aliphatic polyurethane coating technology by providing
faster dry times and higher film builds. Bayer has specific raw
materials and formulation expertise in polyaspartic chemistry, which
are explained in more detail in our Polyaspartic
Coating Technology section.

No matter which system you use, polyurethane coatings deliver numerous
benefits:
- High-performance corrosion protection
- Easy graffiti removal
- Long-lasting color and gloss retention
- High chemical and abrasion resistance
- Fast cure times
- Low maintenance
