Technical Information

Catalysed screen inks are a range of two pack inks possessing excellent adhesion and chemical resistance. They cure to hard heat resistant films with good adhesion to a wide range of difficult substrates. These inks can be air dried or heat cured. Depending on the hardener chosen, a matt or full gloss finish may be obtained.

Type of Stencil Water resistant.
Mesh/Coverage: 90-120T monofilament screens, 110T mesh should give 20 sq m/kg.
Printing Ink and Hardener (catalyst) must be weighed in the correct proportions and thoroughly mixed before use
S1053 Gloss Hardener: Chose this hardener for maximum gloss and flexibility.
Mixing 1 part hardener by weight
4 parts ink by weight
Pot Life 3-4 hours
S2735 Gelled Hardener: This hardener has exactly the same properties as C1053. Its thixotropic nature can be used to advantage where sharp detail or high build are important. Where pinholes are an intermittant problem when printing onto contaminated materials, using this hardener often cures the problem.
S1025 Matt Hardener: This hardener is intended for use where a matt result is required.
Mixing 1 part hardener by weight
1 part ink by weight
Pot Life 6 hours
S2629 Extra Matt Hardener: This hardener also produces a matt finish combined with a thixotropic consistency ideal for sharp detail printing. It gives a more consistant matt finish on long runs than the standard Matt Hardener C1025.
Mixing 3 parts hardener by weight
  10 parts ink by weight
Pot Life 4 hours
When using all hardeners, increasing the percentage in the mix will result in a more flexible cured film and the pot life will be reduced. Decreasing the hardener will result in harder less flexible films and a longer pot life.
C950 Extra Fast Gloss Hardener: This hardener is designed for print runs where two or more colours need to be printed in the working day. C950 reduces the drying time by approximately 40% but the pot life is also considerably shortened. It is recommended that the adhesion of the ink is checked before the print run, as a reduction in adhesion may occur in exceptional circumstances.
Curing Schedules Temperature Touch Dry Cured
80°C 5-7 mins 30 mins
120°C 2-3 mins 10 mins
150°C 1-2 mins 7 mins
At room temperature touch dry in about 3 hours, full chemical resistance and hardness however is not achieved until five days after printing.
Thinners Thinner R11 5-10%
Uses Most metals, ceramics, glass, phenolics, ureas/melamines, acrylics, stoved enamels, treated polyethylene and polypropylene, nylon and some polyesters.
