Flexography: flexographic inks
Flexographic inks are liquid and consist of several elements of different nature.
The main types of flexographic inks are:
-the solvent-based inks
-the water-based inks
-the UV inks
An important feature of the Water Based Flexo Ink in India flexographic inks is that they are transparent and to give them opacity should add white.
Like other inks are composed of resins, dyes (pigments / dyes), solvents and additives.
THE COMPONENTS
• The resins may be natural or synthetic; the most commonly used solvent-based inks are polyamides (solvent: alcohols), nitrocellulose
(Solvents: esters and alcohols) and polyurethane (solvents: esters and alcohols); for water-based inks are used water-soluble acrylic (Solvent: water).
• The pigments and dyes provide color. Their difference is that the dyes are dissolved and dispersed pigments.
• Solvents have the following functions: perfectly dissolve the resins, have the ability to evaporate and keep the viscosity of the
inks. We can distinguish three types of solvents: the so-called true solvent, thinner or accelerants and retardants (ethoxypropanol and methoxypropanol).
To handle a solvent-based ink is required a mixture of 80% alcohol (solvent) and 20% ethyl (diluent).
The main known solvents are: alcohols, esters, hydrocarbons, ethers, glycols, ketones.
• The additives impart certain properties to inks such as resitencia rub or higher brightness, etc. The main additives include waxes,antioxidants, plasticizers, defoamers, surfactants, adhesion promoters, other.
• The varnish is the result of the dissolution of the resins with the solvents and acts as the pigment vehicle.
Water Based Flexo Ink in India is to ensure high standard production, these products are manufactured by using quality assured base materials .
PROPERTIES
The main properties of the inks are given by qualities such as:
-the viscosity (22 ", Ford 4, 20)
-color
-intensity
-tonality
-brightness
-power covering
-cleaning tone
-reología: viscosity, resistance, tack
I -Drying ...
* If the data measuring the viscosity of an ink do not include temperature, it stipulates that it is 21º C.
* Remember that there are two types of viscosity: the static viscosity and dynamic viscosity, viscosity measurements are performed with a viscosity dynamic, ie moving the ink to be homogenized.
