NP349: Polyaspartic Coating

NP349 is a two component 100% solids polyaspartic aliphatic urethane seamless binder for broadcast systems. This material can be used with dried colored sand mixtures to provide an infinite array of color schemes or patterns. NP349 has excellent chemical resistance, hardness, abrasion resistance, UV stability and has an excellent clear gardner color. However, the outstanding feature of this product is its exceptionally quick tack free time for foot traffic.

RECOMMENDED FOR: Recommended for areas where a high build broadcasted floor is desired and installation downtime is very limited. This material can also be applied over a broadcasted or troweled system as a thin to medium build sealer.
