TECTYL 558-AMC
is an amber
colored, solvent cutback, slightly thixotropic wax base corrosion preventive
compound with good water displacing properties. It is primarily intended for
spray application to enclosed boxes, seams, joints and other creviced locations
of vehicles, susceptible to corrosion.
TECTYL
558-AMC is recommended as primer coat for 2-layer systems. After a relatively short
drying period it can be sprayed over with other TECTYL products without sagging
or dripping. It dries to a dark amber colored, translucent, waxy, semi-firm,
slightly tacky film.
Strong penetration and superior
protection: With its strong penetration, TECTYL 558-AMC
will protect the surface against corrosion, even in small seams and crevices
and will displace water where needed.
Excellent underbody corrosion
resistance with dual coating: When applying TECTYL 120, TECTYL 120-EH, TECTYL 121-LV or
TECTYL 122-A on top of TECTYL 558-AMC, the combination makes an underbody
coating with excellent corrosion resistance.
Economic
Efficiency: With a DFT of only 50 microns TECTYL 558-AMC
can protect a big surface with just little amount of the product.
