Flame treatment<\/strong> is a proven and uncomplicated process for the pre-treatment of plastics, metals and glass surfaces. It allows precise control of activation and, with the addition of silane, is suitable for meeting even the strictest requirements.<\/p>\n<\/div><\/div>\n\n\n\n

Surface activation with arcogas\u00ae flame treatment systems<\/h2> \r\n \r\n <\/div>\n\n\n

The principle of flame treatment<\/strong> is quite simple. A flame of up to 1,800\u00b0C passes over the part to be treated. Oxygen and combustion products such as CO\u2082 and H\u2082O are partially present in the flame in an activated form. These highly reactive radicals<\/strong> (e.g. O, OH) can break up the long-chain molecules in the surface of the treated part and bind to the break points.<\/p>\n\n\n\n

This creates polar components in the molecules, which increases the surface tension and wettability<\/strong>. By breaking up the long-chain molecules, the printing ink can also bind better to the surface. Other processes that take place on the surface during flame treatment include invisible roughening<\/strong> and a certain cleaning effect.<\/p>\n<\/div>\n\n\n\n

Special activation of the surfaces<\/h3> \r\n \r\n <\/div>\n\n\n

Arcogas\u00ae flame treatment systems allow an even more specialised activation<\/strong> of the surfaces to be treated, whereby the adhesive properties can be improved even more specifically. This is done by adding certain gases or precursors.<\/p>\n\n\n

\r\n \r\n

Excellent adhesion properties<\/h3> \r\n \r\n <\/div>\n\n\n

By adding a silane compound as an adhesion promoter (arcosil\u00ae process<\/a>), extremely thin silicate layers just a few nanometres thick can be produced, which have very good adhesive properties<\/strong>.<\/p>\n\n\n

\r\n \r\n

Invisible roughening<\/h3> \r\n \r\n <\/div>\n\n\n

The flame treatment roughens the surface<\/strong>. This is so small that it is only detectable on a microscopic scale, but enables better mechanical anchoring.<\/p>\n\n\n

Flame treatment systems for all applications<\/h3> \r\n \r\n <\/div>\n\n\n

We offer flame treatment systems that are precisely customised to your needs<\/strong> \u2013 from laboratory operation to large-scale production. These are easily operated with commercially available gases (natural gas, propane, butane).<\/p>\n<\/div><\/div>\n\n\n\n

How is a flame treatment system designed for pre-treatment?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

Standard flame treatment systems consist generally of a control unit<\/a> and one or more burners<\/a><\/strong>. The performance characteristics of the control unit as well as the number and configuration of the burners have to be specified with respect to the application.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

Is a flame treatment system also worthwhile for small batches?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

Yes, for flame treatment of small batches<\/strong> we offer FTM systems<\/a> for manual flame treatment. Our FTM system is also suitable for use in the laboratory, for repairs or as a standby solution.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

What pre-treatment methods are available?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

Pre-treatment can be carried out using chemical substances<\/strong>, but these are highly reactive and therefore hazardous to the environment and health. In addition, the unavoidable waste has to be disposed of at great cost. These disadvantages can be avoided by using flame treatment instead of chemical processes.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

How does physical pre-treatment work?<\/p>\r\n

<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

We therefore believe that physical processes are the better alternative. The surface is activated either by means of a corona system, plasma or flame treatment<\/strong>.<\/p>\n

Arcotec offers you the technical systems for all four process groups<\/strong> (silica coating<\/a>, corona<\/a>, plasma<\/a> and flame treatment) so that the optimum solution can be found for every application. Simply contact<\/a> us and we will be happy to advise you on flame treatment and all other potential solutions for your production!<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

Why do materials need to be pre-treated?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

But why do materials need to be pre-treated at all? Adhesives and paints adhere poorly to many modern plastics, but also to metal or glass surfaces, as their surface energy is low<\/strong>. Contamination often occurs during production, for example through greases. This problem affects not only films<\/strong>, but also moulded parts<\/strong>. The flame treatment achieves precision cleaning and an increase in surface energy. This can significantly improve the adhesive properties<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div> \r\n <\/div> \r\n <\/div> \r\n \r\n <\/section>\r\n
