Plastics specialist Ensinger has developed its insulbar ESP insulating profile made of electrostatically optimized material specifically for what is known as “coating in the finished assembly”. The plastic TECATHERM 66 ESP attracts the paint particles more effectively than conventional less conductive polyamide, so ensuring a more even paint layer. Particularly in the case of metal constructions with visible thermal insulating profiles, and when working with non-standard solutions whose design makes them difficult to coat, insulbar ESP ensures excellent optical appeal and quality.
Optimized for coating in the finished assembly
“For our customers, the facility for coating in the finished assembly means considerable process and cost optimization”, explains Frank Killinger, Head of Sales for insulbar at Ensinger. “Time-consuming and expensive additional work steps such as foil covering of already painted aluminium shells to protect the surfaces during manufacture of the assembly are no longer necessary. Any optional quantity of assembled profiles can now be produced in advance, with colour selection and painting taking place at a later date. This simplifies stocking and at the same time guarantees maximum colour diversity”.
To allow optimum paint adhesion, Ensinger offers insulbar ESP insulating profiles which have been additionally dust blasted. Dust blasting increases the surface tension to around 70 mN/m by roughening. As a comparison: Conventional polyamide 66 profiles have a surface tension of around 30 mN/m, while for reliable paint adhesion the recommended surface tension is over 50 mN/m. Like all other insulbar insulating profiles, insulbar ESP profiles are capable of withstanding curing processes of up to an object temperature of 200°C without damage.
