Short report:

Within the IGF-precursor project 18035 BG, a plasma-based dry decoating process was developed as an alternative to wet-chemical basic cleaning of elastic floor coverings with the associated cleaning machine technology, in which the use of water and chemicals is dispensed with; furthermore, the personnel expenditure is reduced and drying times before re-filming are eliminated.

The new process was developed in combination with a maintenance coating modified by the addition of suitable additives (e.g. olefins, in particular polyethylene waxes, intumescent or heat conducting agents). However, this modified maintenance film is not suitable for all resilient floor coverings and only for areas of low stress due to reduced adhesion and abrasion resistance compared to conventional maintenance films.

The aim of the research project is to develop a plasma-active maintenance film based on intumescent crosslinkers with optimized adhesion and abrasion resistance for use in areas of high stress, which allows plasma-based dry decoating: This can be realized by developing a two-layer maintenance film consisting of a wax-containing release layer with included long-chain carboxylic acids and thermal conduction agents and a layer containing an intumescent polymer network.

The intumescent polymer network is generated from a commercial care dispersion and a specially developed intumescent crosslinker. The results of the project will provide an economical method for the basic cleaning and re-filming of elastic floor coverings, which is characterized by a high area performance and the elimination of drying times.
