UltraSeal XT plus hydrophobic pit and fissure sealant is a light-cured, radiopaque, fluoride-releasing composite sealant. It is strong and wear resistant because it is a 58%-filled resin and has low polymerization shrinkage. The spiral in the Inspiral™ Brush tip causes shear thinning of the filled, thixotropic resin, reducing its viscosity as it is placed. The resin firms when shear thinning ceases and placement is complete, preventing the resin from running before it can be light cured. Using PrimaDry™ drying agent with UltraSeal XT plus sealant enhances penetration into pits and fissures1 by eliminating moisture that can cause failure in hydrophobic sealants.
Dialight’s LED based High Intensity Strobe was the first all LED unit designed for broadcast towers, stacks and other tall structures. It provides superior surge and lighting protection as well as 360° coverage using three flash heads. Each flash head will operate in white or red mode, allowing for one fixture to meet all FAA high intensity tower types: B, C, F or G. ETL verified to ICAO, FAA & TC standards.
