Technical coating systems for Chemistry & Industry

Solvent-free epoxy and/or epoxy novolac and/or vinylester systems for the gasproofing, waterproofing and protection of concrete and steel tanks, reservoirs, temporary retentions and structures in contact with all types of chemical liquids and gases, acids, bases, however aggressive.

Depending on the nature of the product in contact and the storage temperature, products recommended will be TECHNOPERL® or CHEMPERL® or GELCOAT SV101 or LP 100/512 or 812 or AR100MD4 and CLX or CHEMPERL®

As a general rule, on new or existing concrete substrates or on existing, corroded steel substrates, the recommended solutions will consist of multi-layer, glass-fiber-reinforced systems completed with a finishing coat determined by the nature of the gas/liquid/effluent stored and its maximum temperature of storage. On new steel or steel with a very good condition of surface after preparation, a single-layer coating, applied after blasting and priming, may be sufficient.

In any case, MAX PERLES will provide the appropriate technical specification on request,
taking into account the data supplied on the nature and temperature of the content
and the current condition of the container.

Resin / glass fabric multi-layer lamination gives the systems resistance to existing
and future cracking in a concrete substrate of up to 20/10ths of a mm.
