Product information

Description
TECTYL 120-EH is a filled, solvent cutback, wax/asphaltic base, thixotropic, corrosion preventive compound.
TECTYL 120-EH is suitable for the complete undercoating of undersides of autos, trucks, buses, truck trailers, camp trailers, heavy construction equipment and cargo containers.
TECTYL 120-EH dries to a firm, bronze colored, resilient, tough and abrasion resistant film.

Surface Preparation:
The maximum performance of TECTYL 120-EH can be achieved only when the metal surfaces to be
protected are clean, dry and free of rust, oil and mill scale. Valvoline recommends that the metal
substrate temperature be 10-35 °C at the time of product application.
Avoid direct contact of the product with PVC due to possible material incompatibility.

Application:
TECTYL 120-EH is formulated to be used as supplied. Ensure uniform consistency prior to use.
Continued stirring is generally not required. If the product thickens due to cold storage or loss of solvent
during use, contact Valvoline. DO NOT THIN TECTYL 120-EH. Incorrect thinning will affect film build, dry
time and product performance. Valvoline recommends that the ambient and product temperature be 10-
35 °C at the time of product application. TECTYL 120-EH can be applied by airless spray or brush.

Removal:
TECTYL 120-EH can be removed with mineral spirits or any similar petroleum solvent, hot alkaline wash
or low pressure steam.

Storage:
TECTYL 120-EH should be stored at temperatures between 10-35 °C. Mild agitation is recommended
prior to use. Due to its composition TECTYL 120-EH can be subject to postproduction viscosity changes
during storage.
Under proper storage conditions TECTYL 120-EH can have a shelf life of 3 years minimum.

Caution:
Adequate ventilation is required for cure and to ensure against formation of combustible liquid. THE
PARTIALLY CURED FILM SHOULD NOT BE EXPOSED TO IGNITION SOURCES SUCH AS FLARES,
FLAMES, SPARKS, EXCESSIVE HEAT OR TORCHES. Refer to Valvoline’s Material Safety Data Sheet
for additional handling and first aid information.

Note:
The addition of any product over or under this coating is not recommended. The use of additional
coatings could result in chemical incompatibility, thus affecting the performance of this coating as stated
in the Typical Properties section. If a primer, other than a Valvoline recommended product is required,
written authorization must be obtained from Valvoline.
