NEW FORMULATIONS OF BAYER’S PROVEN BAYTEC COATINGS HIGHLIGHTED AT WORLD OF CONCRETE
18 January 2005 - Bayer MaterialScience AG

Baytec® SPR membranes from Bayer MaterialScience have been proven in numerous applications for more than 30 years.

Now, Bayer is expanding its leadership position in polyurethane coatings with new formulations designed specifically for challenging industrial applications, such as water/wastewater infrastructure; transportation infrastructure; and other outdoor structures, including industrial roofing, stairways, terraces and parking structures.

“Bayer’s Baytec SPR spray systems have stood the test of time in a variety of sealing and corrosion protection applications,” said Steven Reinstadtler, market channel manager, Cast Elastomers/Waterproofing Group for Bayer MaterialScience. “By applying this expertise and chemistry to infrastructure and industrial applications, Bayer is not only responding to a market need for long-lasting protection in these demanding environments, but also demonstrating a continued commitment to thick film coating technologies.”

Bayer will highlight its thick film coating systems at its booth (S11541) at World of Concrete, held Jan. 18-21, 2005, in Las Vegas.

Baytec two-component, 100 percent-solids spray polyurethane systems offer an outstanding combination of physical and chemical properties for industrial applications. These properties include:

Resistance to wear and abrasion;
Excellent tensile strength;
High elasticity and elongation;
A homogeneous seal on cracked, porous and cellular substrates;
Resistance to hydrolysis, ozone and UV radiation;
Good permeability to water vapor;
Corrosion resistance for metal substrates;
Good weatherability and resistance to microbes;
Good chemical resistance.

When reacted to form a membrane, Baytec SPR systems contain both polyurethane and polyurea linkages. According to Reinstadtler, this allows the system to harness the excellent durability of a polyurea along with the flexibility and processability of a polyurethane.

“Because of this desirable combination of properties, we believe that Baytec SPR spray systems offer the best of both worlds,” said Reinstadtler.

Furthermore, Baytec SPR, which can be pigmented to any color, is approved for use by a variety of federal, state and local authorities as well as civil engineering and consulting firms in the United States and worldwide.
