Tectyl™ 5660W FR is a high non-volatile, filled, waterborne, thixotropic, quick drying, fire resistance corrosion preventive compound.
Tectyl™ 5660W FR is developed as an abrasion resistant, sound damping underbody coating for buses, truck cabins, trains and trams where EN 45545 HL2 classification is required. It is also suitable for complete undercoating of containers, trailers, etc.
Tectyl™ 5660W FR cures to a dark-grey, colored, abrasion resistant, resilient and tough film.
Tectyl™ 5660W FR is highly effective in reducing vibrational resonance conditions in structures such as sheet metal panels, floor housings, stainless sinks, and a multitude of other applications.
Tectyl™ 5660W FR will dissipate structure-borne vibrational energy and reduces radiated air-borne noise.

Tectyl™ 5660W FR is water based, non-toxic, non-flammable, and odorless and exhibits exceptional aging characteristics.
