Plastisol primer to prevent migration of the Armor LC Gray dye

   

 

Description


Armor LC Gray - covering low-temperature primer, designed to block the migration of dyes when printing on 100% polyester, mixed fabrics and fabrics dyed with sublimation dyes. Paint does not contain phthalates.

The peculiarity of the paint is the low temperature of drying, which in combination with the chemical composition provides maximum resistance to migration. An important feature of the paint is a significantly reduced viscosity and creamy consistency, which provides ease of printing (even on manual machines), easy passage through the mesh and a smooth surface of the print.

Printing guidelines


• To block migration, an Armor LC print must completely overlap the material throughout the subsequent printing area.

• When working with complex fabrics (for example, migratory camouflage), it is important when printing to get a good layer of ink to block the migration of the dye fabric. In this case, printing with thin grids in two passes with intermediate drying is recommended. For optimal protection against migration, it is recommended to additionally print low-temperature white paint in the same way.

• Use well-shaped forms for optimal performance.

• It is recommended to use meshes with a minimum thread diameter.

• When printing, adjust the temperature and intermediate drying time so that the ink feels dry to the touch. Avoid excessive intermediate drying temperature to prevent possible migration. Depending on the model of drying, 2-3 seconds are usually enough. If the surface of the print after the intermediate drying is hot and sticky, it means that the paint is too dry and you need to reduce the temperature or reduce the time.

• Final drying depends on time and temperature. The best result in terms of product protection, control of migration and reduction of electricity consumption will be obtained while maintaining the recommended drying temperature in the drying chamber and slow conveyor speed.

• Armor LC polymerizes in the range of 132-160 °C (270-320 °F). When printing on fabrics with cotton, thick fabrics, or with a thick layer of paint, it may be necessary to dry at the upper limit of the specified range and increase the drying time.

 

Special recommendation


• Stir the ink before printing.

• Prints should not be dry cleaned, bleached, or ironed with a hot iron.

• The drying test is mandatory before printing starts. Insufficient or excessive drying will result in poor print resistance to washing and poor paint adhesion.

• The temperature on the surface of the impression during intermediate and final drying should be controlled by a pyrometer or other method.

• Responsibility for the correct selection of ink to the printed material rests with the technologist or printer, who selects ink and print parameters.

• Excessive intermediate drying should be avoided, as this can lead to poor adhesion of the ink layers in multi-color printing.

• Before launching the circulation, it is necessary to carry out preliminary tests on unknown types of tissue because of the possibility of the appearance of migration or parasitic staining. Remember, the characteristics of fabrics and dyes may vary depending on the manufacturer and batch of fabric.

• With the correct settings, parasitic coloring of the products does not occur.

• In any application not mentioned in this manual, it is necessary to carry out preliminary tests or get expert advice.
