XF-GL Series Screen Printing Ink

Type: solvent

Printing process: screen printing

Ink type: one and two-component

Finish: glossy

Materials: Aluminium, Lacquered surfaces, Polypropylene not treated, Polyurethane, treated Polyester, treated Polypropylene

If you need to print on 100% Polypropylene (PP) substrates, or cutted with other substances, a preventive pre-treatment is not necessary.

For Alluminium it’s necessary to make preventive tests

Main features:

• Excellent printability
• Glossy appearance
• Moderate solidity for applications that must be exposed to the outside
• Quick drying
• Excellent opacity
• Excellent adhesion even on surfaces with poor wettability, using the relative hardener.
• Excellent chemical-physical solidity
• Pseudo-plastic ink

Because of the versatility of use of this ink, and the possible differences in the quality of the supports used, pre-tests are suggested.

If necessary, help the adhesion of the ink modifying the surface tension of the various supports with specific treatments such as: plasma treatment, corona, flaming (physical treatments), cleaning or degreasing (chemical treatments).

It’s possible to do tests even with post physical treatments.

FX-GL series mixed with hardener has a pot life of approx. 8h (at 20°C).

Higher temperatures and humidity will reduce pot life

(recommended temperature 20-25°C and low moisture content in the workplace).

Used as 2-component ink, FX-GL series has to be mixed with hardener at a specified ratio prior to processing.

Thinner is added after addition of hardener.

The mixed ink should be allowed to pre-react for approx. 15 minutes prior to print.

Certifications: CLP/GHS (EC 1272/2008), Conflict minerals free, EN 71-3, Reach (EC 1907/2006), RoHS

The EN 71:3 Directive is valid for standard shades of one component inks, two component inks, Ink system and Process colors, HD shades and for all not standard shades which do not contain metallic shades, metallic pastes or fluorescent pigments or inks. In order to clarify any doubt on not standard shades, it is always recommended to provide us a specific request.

Eco-sustainability (free of): Animal origin ingredients, Azo dyes, Bisphenol A (BPA), Formaldehyde, G-B Ester, Latex, Melamine, PAH, Persistent organic pollutants, Phthalates (listed in RoHS directive)

Note: shades in the fluorescent color chart contain formaldehyde.

Note: inks are formulated without aromatics naphthas, potential IPA contaminations are minimal.

Outdoor resistance (years): 2

Suitable for outdoor applications for periods not exceeding 3-4 years.

The used pigments have a solidity from 6 to 8 DIN.

XFH-N (10%) hardener is recommended for outdoor applications.

In case of mixing with the transparent bases 70 TR or TP, or with white 160 or 60 BN, the

light fastness and atmospheric agents decrease.

If you want to increase the outdoor solidity, it’s recommended to add 5-7% of UV adsorber to the ink.

Fluorescent shades (refer to the FLUO color chart) are formulated with special pigments which, due to the molecular constitution, do not guarantee high light solidity and are easily decomposed by electromagnetic radiation.

Outdoor exposure cannot be longer than two months.

Drying process: 15 minutes at room temperature

FX-GL series dries physically by evaporation of solvents or through chemical reaction.

Drying times depend on various factors:

• Thickness of printed ink layer (single print, multi-layer print).
• Type and amount of thinners/retarders used
• Type of oven
• Drying temperature
• Type of substrate on which the ink is deposited.

Ink dries physically by evaporation of solvents:

• 15 minutes at room temperature (depending on local conditions)
• 50-60 sec at 50°C in an air circulation oven.

(The test performed in our laboratory was carried out under the following conditions: 8 mt / min, 120.34 screen printing mesh, medium thinner DILUENTE VINILICO at 15%, air circulation oven).

Two-component drying by polymerization:

When the Series FX-GL is added with the relative hardener, at the beginning the ink dries physically, followed by the polymerization reaction which takes place at room temperature (20°C) in at least 5-7 days.

If the printed film is heated in an oven at 80°C for about 20 minutes, the polymerization is completed within 48 hours.

 

Mechanical and chemical solidity:

Alcohol	even as one-component
Cosmetics	as two-component
Detergents	as two-component
Gasoline	as two-component
Greases	as two-component
Oils	as two-component
Surface hardness (Abrasion)
Water	as two-component

 

The tests must be carried out 5-6 days after printing.

Colours range: EXTRA – M, FLUORESCENTI, HD, INK SYSTEM, METALLIZZATI, QUADRICROMIA

 

Please refer to the Glossy, Metallic, Fluorescent, Opaque (HD) and Ink System ink color charts.

The Ink System are 12 colour shades for mixing of RAL, PMS and HKS colours

The metallic shades are available only by mixing the relative pastes with the Transparent Base FX-GL 70 TR.

• Gold paste 75 10-20%
• Gold paste 76 10-20%
• Gold paste 77 10-20%
• Bronze paste 78 10-20%
• Silver paste 79-050 10-15%

The metallic pastes composed with the relative transparent base FX-GL 70 TR, due to their particular composition, can oxidize.

The pot-life of the compounded METALLIC PASTES is about 8 working hours.

The other metallic shades are ready to use.

Fluorescent shades are ready to use.

In the Ink System color chart are present the shades:

1080 yellow, 1081 magenta, 1082 blue, 1083 black, TP paste (CMYK), necessary for making four-color prints.

In the range are also included the following shades :

• 160 HD Opaque white
• 165 HD Opaque black
