In the last years it has been rediscovered its elegance and is also used in the areas of design objects such as lamps, eyewear, handles, household goods, furniture accessories and bathroom furniture, watches, jewellery, technical articles, etc ... thanks to the possibility of modern resins to control with more precision the level of gloss and color of these varnishes.
The elegant texture of the surfaces treated with this varnish makes them unique, giving it personality and pleasant touch.
The wrinkle varnish has an excellent success in the marine industry for standard equipment and custom where it is also used for non-slip qualities as well as their appearance.
Common uses are then linked to customization or restore of car's details and motorbike, made possible by the resistance of varnish to gasoline and bad weather.
The evolution of technology now allows you to have numerous colors without overlay a layer of final colored varnish, for more information about it we suggest to contact our technical staff.
Application and drying of the wrinkled varnish
The finish can be applied by spray only, by a mixed airbrush (air or pump), this is because the success of a wrinkled uniform appearance is related to the homogeneity of the application that can be obtained with the spray only.
The varnish is applied with a nozzle of 1.8-2.5 mm to 3-4 Atm pressure, avoiding dilutions of the varnish. The recommended applicable thickness is 300 microns wet, it needs an high thickness compared to normal varnish to give a wrinkling effect "big" as required by most customers.
Once applied the varnish, after a drying of about 10-15 minutes, is necessary to dry the surface applied at 80°C for 60-90 minutes, at this stage the coated manufacture assume the wrinkled look.
We recommend the cooking at 80°C because drying at lower temperatures can lead to results not uniform or not perfectly reproducible for articles in series, it is suitable for occasional users or privates only.
It is important to note how the pieces after this cooking at 80°C are formally ready for use but for any resistance test it is necessary wait for a time of 15-20 days in order to have the complete crosslinking of the wrinkled varnish; this is due to 'high thickness applied. The artifact is still manageable and can be placed on the market before this time.
It should be noted that the application of varnish on these thickness requires expedients to avoid the casting especially with small supports and with accentuated corners.
General technical information on the Cromas' wrinkled varnish
The wrinkled varnish requires necessarily drying by oven at 80°C, the drying at room temperature leads to a smooth surface without wrinkles, the drying at temperatures below 80°C leads to intermediate results or not reproducible industrially.
Many colors, but not all, are achievable. For example, the total white color can be realized with the application of a second layer of varnish only.
The surface to be painted must not have residues of previous painting and must be completely clean, the application on polished metals needs a previously sanding.
The application on plastics, with or without primer according to their nature, however, requires a Tg or a melting temperature not lower than 80°C.
For industrial applications with furnaces with higher temperatures (eg 130-150°C) is required, however, a permanence at 80°C to form the wrinkles before the complete drying at elevated temperature.
The wrinkled varnish can also be purchased by private users, in order to make the application is however required a minimum experience for spray application, especially to avoid the casting at these thicknesses.
