Contractors floored by Bayer's new raw materials for concrete topcoats

Engineered polyisocyanates for topcoats offer numerous advantages over traditional topcoats for decorative concrete

Las Vegas, January 25, 2012 — Coatings applicators have long struggled with changing temperatures and humidity levels in the field. Bayer MaterialScience LLC recognized this market need and developed a new raw material that translates into topcoats for decorative and industrial concrete that are more user-friendly.
Bayer scientists have developed an engineered polyisocyanate that, when used in conjunction with polyaspartic coatings raw materials, produces a revolutionary topcoat that addresses application difficulties caused by fluctuating temperatures and humidity. Contractors and applicators can benefit from its advantages, such as:

  • Ability to be applied in a wide range of humidity levels while maintaining consistent cure
  • Longer re-coat window
  • Good low-temperature cure properties
  • Fast curing times
  • Excellent color and gloss retention
  • Low volatile organic compound levels
  • Good to excellent abrasion resistance

Topcoats formulated using engineered polyisocyanate raw materials along with polyaspartic resins from Bayer can be used for both interior and exterior applications in commercial, industrial, retail and residential flooring. Using the new polyisocyanate raw materials in combination with polyaspartic materials results in a final coating with a 1:1 mix ratio for easy formulating.

According to Mike Jeffries, strategic technology manager, Bayer MaterialScience LLC, "This new concrete topcoat development is easier to work with in the field, enabling applicators to be more efficient. Its fast cure time and high build also allow for a rapid return to service, potentially saving both time and money."
