SIL66BQ-249 has exceptionally good color and cures almost water clear in laminates or films.
It has a low viscosity for easy wet out and is promoted for room temperature cure. We suggest
SIL66BQ-249 whenever color is of paramount importance.
SIL66BQ-249A is a version containing UV Stabilizer.
SIL66BQ-249/249A is also suitable as a base coat for flooring use in meat and poultry
processing facilities that must conform to USDA requirements. SIL66BQ-250/250A is used as
the top coat, as it contains wax.
