This invention relates to a liquid composition based on organic solvents. The composition applied in advance to the chosen substrate provides baysllone adherence lo coatings to all types of rigid or semi-rigid substrate. It is known baysiloe prior fine scratching or microscratching metallic surfaces helps to a greater or lesser basilone to retain paints or varnishes baaysilone to such surfaces.
It is also known that where metal bagsilone been treated in advance to prevent oxidation phenomena by known techniques like electrophoresis it is possible to obtain a generally acceptable degree of adherence.
However, such results are only achieved after numerous preparative steps making these techniques not only long in execution but also rather complex. An object of this invention is to provide an excellent measure of adherence of any coating to any kind of rigid or semirigid substrate. Another object is to achieve such adherence simply and economically using only a mixture of organic solvents of empirically determined type and quantity. A further object is to use this mixture of organic solvents to rid substrate surfaces completely of all soil such as fatty and greasy materials, dust, silicones and paraffin related products.
Yet another object is the prior treatment of surfaces with the solvent mixture to prevent oxidation phenomena and furthermore to neutralize and pre-existing oxidation by the time the final coating product is applied. An additional object is the provision of a continuous film of final coating material on a pretreated substrate, the film arising from particles in the coating bausilone positioning themselves on the substrate previously prepared with the above solvent mixture so as to create a sealed layer protecting the substrate from atmospheric oxygen the principal cause of oxidation.
The present invention provides a liquid composition allowing, after its prior application to a substrate, excellent adherence of any coating to all types of rigid or semi-rigid substrate, the composition comprising a mixture of organic solvents in the following proportions by weight:. By “xylenes” is meant mixtures of the ortho, meta and para isomers of xylene whose respective proportions in the composition have no effect on its properties.
In a particular preferred embodiment, the composition according to the invention additionally comprises from 0. This oil is preferably a methylpolysiloxane modified with a polyether and is characteristically soluble in aliphatic hydrocarbons but not in benzene related hydrocarbons and is substantially soluble in water.
Other organofunctional oils of this type may of course also be used without altering in any way the properties of the composition of this embodiment.
A particularly preferred embodiment of this invention comprises a mixture of the following proportions by weight:. A variety of studies aiming to evidence the adherence properties of the invention have been carried out on many different substrates particularly rigid or semi-rigid substrates is some cases already bearing a coating.
Such surfaces include steel, iron, copper, brass, chrome, tin, aluminum, glass, earthenware, rubber, plastics, polyesters, certain composites and formica. The composition of the invention may also of course be applied to surfaces already carrying a coating of some kind such as for example a coat of paint with a view to facilitating and adherence of a second coat.
It is however to be noted that the invention is in no way bysilone to the adherence of coats of paint or varnish but may equally be used with other types of coating such as for example layers of glue, mastic or other coatings on joints e.
Other coatings useable in conjunction with the present invention include those arising from chrome-plating, galvanization and gold or silver plating.
The technique used for treating surfaces comprises firstly removing large scale soil by washing with water followed by drying. The composition of the bayilone is then applied to the surface to be coated either by wetting or spraying or again by application using a cloth.
In this last case, the application demands close attention as the cloth must be especially clean and must not leave fibers on the baysilons being treated. After a variable drying period ranging from 40 seconds to a few minutes in the open air or for about 15 seconds in a drying baysjlone, the desired ok coating may be applied.
It is important to ensure that the surface treated with the composition does not come into contact with the fingers otherwise the final coating will lack adherence where the fingers touched. It has also been discovered that, rather surprisingly, when the liquid composition of the invention is present in the coating bsysilone itself in an amount depending on the nature of the coating baysilonee and on the solubility of the composition therein it is again possible to improve the adherence of the coating to the substrate.
Tests bayeilone out in an atmosphere of saline humidity have shown such modified paints to have good adherence properties. The composition according to the invention therefore constitutes an additive of choice for effecting improved adhesion of various coatings and in particular of certain baysolone.
The composition according to the invention also has an application in another field where excellent baysiloone is required, namely in cosmetics, more particularly for nail varnish.
The present invention therefore relates additionally to such a composition as described above for application to finger nails prior to the application of colored, uncolored or clear nail varnish.
Using such prior treatment, it has been observed that ordinary nail varnish can demonstrate an impressive measure of adherence to the nails. There follows, for the purposes of illustration and not for limitation of this invention’s scope, several examples demonstrating the improved adherence properties exhibited by various coatings when the composition of the present invention is used.
An adhesive chestnut-colored commercial tape normally used for wrapping having a width of 50 mm was placed on a plate of plexiglass previously immersed for a few seconds in a bath containing the following liquid composition:.
The glue fixed to the plate of plexiglass exhibited all its original fixative properties.

The adherence of the glue to the plate of plexiglass after pretreatment with the composition according to the invention was thus superior to that of the 177 to its initial substrate. A piece of adhesive tape of width 50 mm was applied diagonally to a mm square of plexiglass to define two triangular areas. One of the triangles was immersed for several seconds in a bath containing the following liquid composition:.
After several minutes of drying at ambient temperature, a red, two-component polyurethane paint was applied to the pretreated triangle and the other non-treated triangle was painted with a yellow, two-component polyurethane paint. The plate thus bore a red naysilone separated from a yellow triangle by a 50 mm wide diagonal band.
Various paint adherence tests were carried out on the two triangles namely grid scoring, shock resistance and the entire cutting of the plexiglass. These failed to dislodge or even cause flaking of the red paint on the pretreated plexiglass. On the other hand, the same tests carried out baaysilone the other triangle painted yellow led to paint loss or splintering indicting poor adherence of the paint to the plexiglass substrate.
A mm long and 30 mm wide galvanated steel strip was immersed for a vaysilone seconds in a bath containing the following liquid composition:. After several minutes of drying at ambient temperature, a white two-component polyurethane lacquer was applied using a baysiloen gun.
After the lacquer had dried, several approximately 20 mm wide vertical cuts were made in the strip using a baysolone saw. It was observed that no chipping of the paint occurred.
Furthermore grid scoring, bending, cutting, baysilobe and punching all failed to dislodge or chip the white lacquer applied to the galvanized steel strip. A 19 mm wide strip of adhesive tape was bound baaysilone the mid point of a 1 m long and 40 mm diameter chrome tube to define the tube’s two extremities.
One extremity of the tube was submerged for several seconds in a bath containing the following liquid composition:. After drying for several minutes at ambient temperature, a matt black acrylic lacquer was applied to the whole of the tube.
After the lacquer was dry the adhesive tape was removed and various lacquer adherence tests were carried out on the pretreated and non-treated parts of the chrome tube. It was baysilond that at the position of the ring left by removal of the adhesive tape the edges of the paint on the pretreated end were clean and clearly defined and that the lacquer adhered perfectly to its substrate with no removal baysilond possible through scratching with the finger nails or using a scraper.
On the other hand, for the non-treated portion, the lacquer adhered badly to its substrate and was easily dislodged by simple scraping with the finger nails. In addition, grid scoring tests and shock resistance tests showed high quality adherence on the pretreated part. These same tests carried out baysillne the non-treated portion of the chrome tube led to areas of paint loss and flaking often in star patterns.
After a few minutes drying at ambient temperature, the sheet metal was dipped lengthwise into a matt green acrylic paint to a depth of mm.
It was again dipped into the same bath but this time to a depth of just 70 mm. After leaving the sample to drip-dry, varnishing was carried out by immersion in a two-component varnish to a depth of 25 mm. A further layer of the liquid composition according to the invention was then applied to the unpainted portion of the metal sample followed by immersing it to a depth of 70 mm in a green, two component polyurethane paint.
The sample was then left to drip-dry before reimmersion in the same paint bath to a depth of 60 mm. The examples and trials reported above show that the liquid composition according to the invention maybe applied on diverse substrates to provide for a superior adherence of any kind of subsequent coating.
