LABFAST LO 85

The LABFAST LOW ODOR is a two-component (1A:1B), non-yellowing, low odor polyaspartic floor coating system. The LABFAST LOW ODOR is used as a clear topcoat and a colored base coat using a common hardener. High solids versions (85% and 90%) are available as well as a prolonged working time version (+) and a fast cure version (-). The system provides a quick turnaround with very rapid curing time with a tack free as low as 45 minutes* allowing the installation of the floor system in a single day. The product displays excellent curing capability even at very low temperature levels. This product offers superior mechanical and chemical properties and is low maintenance. It also displays a superior aesthetic finish and excellent UV stability which makes it ideal for interior and exterior applications. We recommend the utilization of the LABTEC Vinyl Chips in combination with LABFAST/LABSHIELD products. Two- or three-coat systems can be considered.

LABFAST® LO 85 is a high-solids, low-odor, non-yellowing polyaspartic coating system used primarily for concrete floor coatings. It is designed for both base and topcoat applications and is particularly effective in systems utilizing vinyl flakes. This product allows for fast-track flooring installations that can be completed in a single day and is suitable for both interior and exterior use.
