* Results depend on substrate, geometry of parts,type of application processes and type of basecoat.

FUNCTIONALITIES

Lubrication

ZINCROSEAL® allows to obtain a stable and controlled friction coefficient in the range of 0.10-0.16. It provides outstanding tribological performances and stability regarding multi-tightening with various counterparts materials (cataphoretic paint, aluminum alloys, cast iron and steel) while avoiding stick-slip problems. It also offers excellent behaviour in loosening tests, including at high temperature.

0.10-0.16

Coefficient of friction (ISO 16047)

* Measured on GEOMET® 321/720.

Corrosion protection

ZINCROSEAL® provides superior corrosion resistance to conventional coatings such as phosphate/oil, electrolytic zinc plated, mechanical zinc plated, and phosphate/paint, as evaluated by the standard Salt Spray (ASTM B-117). The standard performance exceeds 400 hours of resistance and can reach 1000 hours when applied on GEOMET®.

Chemical resistance

Resistance to industrial solvents and automotive fluids.

No hydrogen embrittlement

Implemented via non-electrolytic application processes. This avoids the hydrogen embrittlement phenomenon that causes cracking of metals.

APPLICATION

Processes

ZINCROSEAL® is applied via bulk dip/spin, rack dip/spin, spray or electrostatic spray. This variety of processes allows to coat all types of parts, even those requiring partial coating, or with recessed and hollow surfaces. Moreover, they are non-electrolytic and thus avoid the phenomenon of hydrogen embrittlement which causes cracking of metals.
