- Description
- Technical specification
TEROSON® WT 218 FR 200 is an underbody coating compound based on an aqueous synthetic resin dispersion, which is spray applied using airless equipment. It demonstrates fire retardant properties, and fulfils HL 2 requirements in accordance to railway fire norm EN 45545-2. Its sag resistance on vertical surfaces, when spray applied, is above 4mm per one application layer. The material can be dried at room temperature or, for faster drying, at temperatures up to 70°C (158°F). Drying time depends on layer thickness, room temperature and ambient air humidity. TEROSON WT 218 FR 200 can be applied by hand, e.g. spatula, for smaller areas or touch-up jobs.

FAQ
Material is typically applied with an airless sprayer. Specifications are as follows: Primary Pump System with a pressure ratio of about 45:1 or higher, for example Graco Series G92A, Model 220-106, About 230 cm³ or higher output per pump cycle, The pump needs a fixed pump-tube, or the pump is mounted on a follower plate, Most pump types work with a ball type foot valve, A damper for the pulsation of the piston pump, All parts must be a high-pressure rated.
Airless pistol with an adjustable Titan nozzle ( 0,53 - 1,37 mm) like from TITAN series 341-049
TEROSON WT 218 FR 200 can be sprayed in an airless spraying process at 80 to 100 bar (1200-1450 psi)
Hoses require a 10 - 13mm internal diameter. Max. length is 25m.
TEROSON WT 218 FR 200 is designed to be directly applied to vehicle shell. It is dark grey so painting is not required when applied to the under surfaces of rail vehicles
The main function of TEROSON WT 218 FR 200 is anti-stone protection, but it can also be used for noise reduction or as a sealant on the interior or the exterior.
