SurTec and Henkel Pretreatment Chemicals

We are the UK partners for SurTec and Henkel and distribute a range of their pretreatment materials to the UK market. We not only supply products, but also provide full support and technical back-up.

‘Pretreatment’ is the process of chemically treating metal surfaces, usually by cleaning and conversion coating, before applying wet paint, powder coating, electroplating or another metal treatment process.

Pretreatment processes from Trimite enhance the adhesion, appearance, anticorrosive performance and lifetime of subsequently applied paint or powder coatings.

Trimite has been a leading supplier of process chemicals to the metal pretreatment and plating industries for many decades. We also pride ourselves on the degree of technical support and testing assistance we can provide for the pretreatment market, either on-site at your own facilities, or in our own laboratories.

We run Training Courses for pretreatment, so your operators can get the best results from Trimite products.
