HG Screen Printing Ink for PlasticsA solvent-based ink series known for fast-drying speeds and high gloss on a wide range of plastics. HG inks are suitable on thermoplastics, especially acrylics, rigid and plasticized PVC, CAB, various types of polystyrene, and polycarbonate. HG inks are an excellent choice for hi-tech graphics..

Technical
PROPERTIES Screen printing inks HG are weather resistant, can be processed easily and they have a relatively mild odour. The colour shades of HG series are highly brilliant despite the fact that they are limited to those pigments which provide maximum light fastness and resistance to plasticizers and solvents. Opacity is medium. As all air drying screen printing inks retain solvents to a certain degree (solvent retention) tests for adhesion and durability on the substrate should not be carried out until one or two days after printing. Due to the aggressive solvents contained in gloss inks HG plastics likely to form tension cracks should be decorated only in sheet form. Also, care must be taken to avoid tension corrosion with mouldings(especially polystyrene and acrylics). COLOUR SHADES Only lead free pigments with a light fastness of 7-8 on the wool scale (DIN 16 525) are used for screen printing inks HG. If base shades are mixed with a high content of white or varnish light fastness is reduced. HG inks can be reduced to semi-transparent shades by adding transparent paste HG/TP or binder HG/B. If, however, the colour shades are reduced a lot, light fastness is reduced as well. Mixing ratio of printing ink to transparent media should not exceed 1 : 1. The colour shades of HG-NT inks show heavy-metal free pigmentation and correspond to the requirements of EN 71, part 3, safety of toys, migration of certain elements. ADJUSTMENT FOR SCREEN PRINTING DRYING Special care should be taken in multi-layer printing when printing onto two sides of the same substrate. When rack drying these inks, quick air circulation is required in order to prevent solvent build-up within the rack, which results in longer drying times. ADDITIVES If, in some cases, degree of gloss has to be increased we recommend addition of binder HG/B. However, opacity of the plastic inks mixed with this binder is reduced, so that this additive is only recommend for light substrates. If problems due to static charge appear use the proper additives (Wiecostat). MISCIBILITY The opacity of screen printing inks HG and SG e.g. may be improved by addition of printing ink types PK, PK-Jet and J, while gloss of the latter may be improved by addition of HG or SG. However, when mixing the individual screen printing inks consider that the properties of the original printing ink change in reference to drying and conduct towards the substrate. When overprinting bronze inks with a regular screen ink consider that in most cases screen inks with a regular opacity do not have sufficient adhesion on the bronze coating. This problem is often solved by adding approx. 10% binder HG/B to the screen ink prior to overprinting. It will also help if the bronze content is as low as possible. As bronze prints tend to oxidation we recommend overprinting with clear varnish HG/E50 or SG/E50. When overprinting bronze inks with regular pigmented screen inks or clear test for adhesion (finger nail test, tape test) prior to starting a print run. There is also a readily mixed AB bronze available which is relatively resistant against oxidation and weathering.

SG Screen Printing InkSG inks are very quick drying screen printing inks. They show high gloss and a mild odour. Due to their fast drying and long screen openness SG inks are very suitable for high speed printing (cylinder printing machines) and for printing from roll to roll. Especially for printing onto PVC self adhesive foils and polystyrene boards. Also suitable for rigid PVC, polymethylmethacrylates (acrylic glass) and cellulose acetobutyrates. Not suitable for polyolefines (polyethylene and polypropylene). Features
Technical
Screen printing inks SG show medium opacity. They are weather resistant and therefore suitable for outdoor advertisement. SG inks are miscible with all plastic inks of Coates Screen Inks GmbH, (PK, PK-Jet, J, CX, HG and SG inks can be formed. The SG colour shades do not change if subjected too heat (180-200°C; 356- 392°F) for short periods of time. However, forming tests are necessary. PIGMENTS AND LIGHT FASTNESS The colour shades of SG-NT inks show heavy-metal free pigmentation and correspond to the requirements of EN 71, part 3, safety of toys, migration of certain elements. ADJUSTMENT FOR SCREEN PRINTING DRYING BRONZE INKS When overprinting bronze inks with a regular screen ink consider that in most cases screen inks with a regular opacity do not have sufficient adhesion on the bronze coating Readily mixed AB bronzes are available upon request. These bronzes are relatively resistant against oxidation and weathering and have a better storage life than mixtures of bronze paste and binder. CLEANING OF STENCILS AND TOOLS PACKING

ZGL Screen Printing Ink for Glass & CeramicsScreen printing inks PP are suitable for printing onto untreated polypropylene [Corriboard]. Due to various degrees of polymerization as well as contents and fillers the substrate polypropylene shows an undefined Features
Technical
The opaque colour shades of ink series Z/GL were especially adjusted not to change their colour shade after mirror imaging like transparent inks do. For mirror imaging it is essential that the substrates are thoroughly cleaned with cleaning agents used in the glass industry (e.g. Ceroxid) prior to printing. The ink film must also be completely cured. Depending on the components of the protective varnish applied to the reflective coating slight bleeding may occur. However, this only happens if very bright varnishes are used, not with the commonly used brown or green protection varnishes for reflective coatings. If white or bright varnish is required, only colours of the C-MIX 2000 range can be used.. PIGMENTS AND LIGHT FASTNESS The colour shades of SG-NT inks show heavy-metal free pigmentation and correspond to the requirements of EN 71, part 3, safety of toys, migration of certain elements. ADJUSTMENT FOR SCREEN PRINTING Depending on room temperature the pot life is approx. 12 hours. Mixed bronzes show reduced pot life. An addition of 3-5% VM3 (flow agent) will be helpful if flow problems occur. However, this additionmay lead to wetting problems if the prints are to be mirror-imaged.

TZ Screen Printing Ink for Cotton, Nylons and LeatherSpecial screen inks for printing onto various textiles, either natural or synthetics, especially suitable for cotton. When printing onto synthetic fibres pretests are absolutely necessary. Application e.g. for printing on sportswear, T-shirts, bags etc. Features
Technical
The mixing ratio is 10 parts ink to 1 part hardener ZH. 2-componente textile inks TZ show goodresistance against laundering at temperatures of approx. 60°C (140°F). When washing at 95°C(185°F) fading is possible depending on colour shade and type of fabric. There is also good resistance against various solvents used in dry cleaning (e.g. chlorinated hydrocarbons, benzines etc.). However, as the solvent resistance depends on the type of fabric printed upon and the solvent used, pretests are necessary. Textile inks TZ are highly elastic, lightfast and weather resistant (light fastness of pigments 7-8 according to DIN 16525, wool scale). Therefore TZ inks can be used for textiles subjected to weathering. However for outdoor use TZ inks have to be processed as 2-component ink. For less demanding jobs this ink type can be processed as 1-component ink resulting in a relatively soft grip. It is suitable to usea relatively coarse fabric (not exceeding 90 threads/cm). When ironing printed textiles at mediumsetting (wool, silk), textile inks TZ are not affected. PIGMENTS AND LIGHT FASTNESS The colour shades of TZ/NT ink and TZ inks according to C-MIX-2000 show heavy-metal free pigmentation and correspond to the requirements of EN 71, part 3, safety of toys, migration of certain elements. ADJUSTMENT FOR SCREEN PRINTING Screen inks TZ can be processed as 1- or as 2-component inks. If higher resistances are required (washing machine resistance and the like) TZ has to be mixed with hardener ZH prior to processing. Mixing ratio is 10:1 parts by weight. Pot life is 8 10 hours. Mixed bronze colours will reduce pot life. Screen Inks TZ are adjusted to printing consistency using thinners VD 20, VD 60 and retarder VZ 25.
