The flame coating or even
flames silicatization called st one for many years
proven and cost-effective treatment for functional or adhesion improved layers to surfaces.
This procedure applies to the combustion chemical vapor
deposition, C-CVD (chemical deposition of layers under atmospheric pressure).
The flame pyrolysis with flamprico Special Gas is a cost effective and economical
solution.
For this purpose metal oxides can be produced for
a variety of applications by means of suitable precursors.
When gasflame-pyrolyse these substances are pyrolyzed in the gas flame to the
respective metal oxides.
Here are some examples:
Adhesion promoter and primer are substances that produce in the
interface region of two substances, a chemical Compound.
Base material of our products:
flamprico adhesion promoters and primers are used
successfully for a variety of applications to customers for many years
The
self-developed and by us manufactured adhesion promoters and primers may be used for the following substrates and applications:
Plastic surfaces to printing, gluing or coating / lacquering is very
problematic.
Without this an appropriate bonding agent or primer or a
suitable surface such as activation can use the
flamprico flame pyrolysis or surface activation of this be bound to failA plastic such as the group
of polyolefins have a nonpolar structure. That means they are made of very long
polymer chains without active OH or COOH groups.
In the processing of the plastic such as
Printing with UV inks in digital or screen printing method has the ink through the long polymer chains no way of chemical bonding, and also their adhesion is worsened by the too low surface
tension.
flamprico plastic bonding agent
this is an adhesion promoter, specifically for polypropylene has been devloped.
Even with other plastics
and substrates a test is recommended.
flamprico special cleaner
This cleaning fluid cleans and activates the surface in one pass through the special composition developed by us, and is an affordable option for your process
Surface activation of plastic through a flame with a gas flame
The surface is flamed with a gas
flame.
It is
important to precise adjustment of the gas / air mixture to provide the optimum excess oxygen permanently and uniformly available.
Here is broken in the surface of
the plastic molecule chains and instead present in the flame active OH and COOH groups involved.
This chemical reaction formed in the originally nonpolar Material Plastic polar
groups.
This is demonstrable by a significant increase in surface tension.
It leads to improved wetting of the surface and to
improve the adhesion, and this without adhesion promoter.
The low surface tension is the
reason that liquids such. B. accept ink, adhesives or paints a cone shape like figure.
At a higher surface
tension of these runs better on the surface, forms a larger interface to the substrate and thereby increasing the adhesion forces.
