Our sealer Products

DR. HESSE offers high-performance sealers for zinc, zinc-iron, zinc-nickel and hot-dip galvanized surfaces. HOTSTAR and HESSOTOP enable corrosion protection and functional surface properties to be combined precisely – from defined coefficients of friction and high temperature resistance to formable, visually uniform protective layers.

Our sealing systems are designed for industrial series production processes in the automotive industry, screw and fastening technology, as well as window, door and hardware technology. Whether screws, fasteners, fittings or functional components: DR. HESSE helps manufacturers and electroplating shops reliably combine demanding corrosion protection requirements, reproducible surface properties and cost-effective process management.

HOTSTAR DE & FR Versiegelungen – lösemittelfreie High-Performance Sealer mit optimalem Korrosionsschutz, temperfähig bis 120 °C, definierten Reibungszahlen nach VDA 233-101 und vielseitiger Einsatzmöglichkeit.
