POLYSIL primers, paints and adhesives for plastics
POLYSIL products have already proven themselves in manufacturing for a long time. Primers, paints and adhesives for industrial applications contain the special POLYSIL active ingredient and ensure an improved workflow with fewer work steps and best results.
POLYSIL primers for plastics such as polypropylene
With POLYSIL, complex pre-treatment processes can be saved even if multi-layer coatings are required. Because on plastics such as polypropylene, POLYSIL one-component primer provides for firm adhesion that can be overcoated with commercially available one-component or two-component paints.
POLYSIL primers are available in various variations – as standard primers and as electrically conductive one-component primers for production-line painting. All POLYSIL primers are characterized above all by the fact that they adhere to non-pretreated non-polar plastics and even to fibre-glass-reinforced polypropylene. In addition, the electrically conductive 1-component primer forms an electrically conductive dry film. The paints to be applied afterwards can be applied electrostatically on this surface. The loss that often occurs when applying primers to smaller surfaces is avoided. The atomized paint follows a trajectory specifically oriented in the direction of the part to be painted.
POLYSIL one-component and two-component single-coat paints
With POLYSIL one-component and two-component single-coat paints for plastics, you can complete the painting process in a single operation including surface activation and coating.
With POLYSIL paints, costly pretreatment of non-polar plastics such as tempering, flame treatment or sanding, as required for other paints, are a thing of the past.
POLYSIL one-component single-coat paints for plastic surfaces
POLYSIL one-component single-coat paints are absolutely plasticizer-free, yet slightly thermoplastic and permanently elastic. As a result, they do not become brittle and can even withstand thermal expansion and cooling contractions of a component without running the risk of stress cracks or other damage.
Various one-component single-coat paints are used to meet different requirements. The standard single-coat paint N1440 is particularly suitable for plastic surfaces that are not exposed to the weather, as is the case for electrical appliances.
However, there are also special one-component single-coat paints that are weather-resistant and UV-stable. These include, for example, the POLYSIL N1445 single-layer coat. This was specially developed for painting plastic façade elements, which would only have a limited shelf life without the additional protection provided by paints, simply because of their UV sensitivity. The visual enhancement achieved by painting is, of course, another added benefit. This paint, which has been specially developed for all plastic surfaces exposed to wind and weather, is based on binders that have long proven themselves in outdoor use. They are highly waterproof, UV resistant and particularly resistant to water and chemicals. Even in the often acidic atmospheres of industrial areas.
For WPC composites (WOOD-Plastic-Composite/Wood-PP), which often consist of half renewable raw materials, POLYSIL has also developed a special single-layer coat, the POLYSIL N1448.
POLYSIL two-component single-coat paints for plastic surfaces
POLYSIL two-component single-coat coatings are much more scratch-resistant than the one-component single-coat paints. They are therefore ideal for surfaces that either require higher scratch resistance or better resistance to chemicals such as cleaning agents.
For plastic surfaces that should neither scratch nor be exposed to the weather, we recommend the POLYSIL two-component single-coat paint N3440.
POLYSIL N3445 is also a special product among the two-component single-coat paints, which is suitable for single-layer coating of plastic surfaces exposed to external weathering. This two-component single-coat paint is also suitable for facade elements and WPC components, for which increased resistance to mechanical effects is required.
POLYSIL adhesives for plastics
Plastics such as untreated polypropylene or expanded polypropylene (EPP) can even be permanently bonded together using the toluene-free contact adhesive Bond-O-Sil N1000. It is also possible to bond them to other materials such as metal, glass, wood or textiles. Time-consuming work steps can also be saved here, as the surfaces to be bonded neither have to be pretreated nor sanded. The only prerequisite for a good end result is that the parts must be clean and free of oils. The adhesive Bond-O-Sil N1000 can then be applied to both sides. After the subsequent airing and strong compression, the parts are firmly bonded and can immediately be subjected to further processing. The maximum adhesive strength is reached after 48 h at 20°C. Bonding of PE is not recommended.
