New Coating Meets More Stringent ICC-ES Compliance Criteria

SPRING, TEXAS, Jan. 15, 2010 — Bayseal™ IC provides builders and spray foam applicators with a cost-effective and easy solution to comply with the new ICC-ES AC377 acceptance criteria approved in June 2009 and now in effect. Bayseal™ IC coating has been tested and approved for use with either Bayseal® OC (open-cell) or Bayseal® CC (closed-cell) spray polyurethane foam (SPF) insulation in attics or crawlspaces. Bayseal™ IC coating, manufactured by BaySystems™, which is the global polyurethane systems business of Bayer MaterialScience, is an ignition barrier alternative that can be applied at low application rates in a single coat and meet the new, more stringent test criteria.

Applied at a thickness of only five dry mils over either the Bayseal™ OC or Bayseal® CC/PP foam insulation products, Bayseal™ IC has the lowest application rate in the industry today. This coating thickness equates to a rate of only 0.6 gallons per 100 square feet, allowing rapid one-coat application and short drying times.
Other benefits include:

Cost effectiveness; Bayseal™ IC coating has lower installed cost compared to currently available products and alternative technologies.
Easy cleanup; Equipment can be flushed with water.
Environmental sustainability; Bayseal™ IC coating is a low VOC (volatile organic compound) water-based, single component, fast drying coating.
Versatility; Bayseal™ IC coating can be used with both open- and closed-cell SPF.

“Bayseal™ IC coating is so easy to use, which is really beneficial to us as contractors,” Bobby Patton, vice-president of Thermacote Systems, said. “It’s also a very cost effective product, which allows my company to be a market leader,” he added.

Thermacote Systems is an SPF applications contractor and an energywise™ preferred contractor; energywise™ is a program from BaySystems™ that combines energy performance analysis, heating, ventilating and air conditioning (HVAC) system sizing, and SPF insulation to guarantee homeowners substantial savings in energy costs.
It is important to note that Bayseal™ IC coating is only approved for use with either the Bayseal® OC or Bayseal® CC/PP foam insulation product to meet requirements of the new acceptance criteria. Any other SPF systems must be independently tested with Bayseal™ IC coating.
