MESH TREATMENT
& STENCIL PRODUCTION
Suncoat Mesh Treatment Products
Suncoat Chemicals include several products which have been formulated with ever increasing environmental awareness in mind. Ways are continuously being researched into manufacturing products with reduced environmental impact.
Emulsifiable Screenwashes
Suncoat Emulsifiable Screenwashes have been specially formulated for the removal of ink residues prior to the application of stencil strip. These can be used in conjunction with Alkaline Paste or Haze Remover to assist in stain removal..It should, however be stated that direct discharge to drainage may not be acceptable to the water authorities. Customers should check with the relevant authority.
26-041
contains no cyclohexanone and as such is a “cleaner” product, whilst still retaining good solvent power. It should, however be stated that it’s direct discharge to drainage may not be acceptable to the water authorities.
YC21705 EM
Emulsifiable Screenwash is a blend of slower evaporating solvents slightly stronger in action than the above, specially designed for manual application and in automatic screen reclaiming machinery. Again, it should be stated that it’s direct discharge to drainage may not be acceptable to the water authorities.
It’s also very useful in removing those oil stains off your concrete drive, but don’t use it on tarmac because it moves that as well!
YC20700 EM
This Product is a Hazard Label Free emulsifiable screenwash, based on natural products, which is virtually fully biodegradable whilst retaining excellent performance. It contains no VOC’s which makes it more environmentally friendly. It’s acceptability for discharge to drains should be checked with your local authority.
Hydrosolve YC935
A screen cleaning product which is used diluted with water, especially suitable for UV and plastisol inks. It is also Hazard Label free. It has been developed for application by hand and in automatic screen washing units, produces little foam and can be used in combination with Easyclean Concentrated Stencil Stripper to clean and de-coat screens in one operation. It’s acceptability for discharge to drains should be checked with your local authority.
Stencil Removers
Suncoat stencil removers have been formulated to facilitate the decoating of direct, direct/indirect and capillary action photo stencils from all synthetic meshes. The products used suit the preferences if the individual user and, at usage strength are environmentally acceptable, however one should check with the local water authority before discharging to the drains
YC28 Concentrated Strip Liquid
is diluted with water at 1:20, but will often work at dilutions of up to 1:40 ! Very economical to use.
YC14 Diasolve Strip Liquid
A ready to use strip liquid.
YC175 Diasolve Strip Paste
is a ready to use gel which will cling to the mesh whilst working
Easyclean Stencil Treatment system
Combining the effects of ink removal, stencil removal and degreasing, this new two part product is hazard label free, biodegradeable, VOC –free, and virtually odour free! Furthermore it is actually diluted 50/50 with water before use! Very effective and time saving, a dirty screen from the press room is converted to a clean, de-greased, stencil-ready screen in one operation
Mesh Preparation Products
YC155 Alkaprep Paste
is designed for both the removal of stubborn stains in used screens, and for the degreasing of new screens, and may used with an emulsifiable screenwash as a ghost image or haze remover. As a strong caustic paste it is also useful for stripping paint and varnish from wooden furniture, but please be careful when using and hosing off
C135 Stainaway LV
A low caustic, low viscosity, bleach based stain remover suitable for the removal of UV ink stains, both conventional and water based. It can be applied either by brush or stainless steel coating troughs and may be used in conjunction with emulsifiable screen washes. Best left to dry on the mesh, even in a drying cabinet. Very Good!
Haze Free Liquid
A low odour, single component stain remover designed to remove both ink and diazo staining without the need for post drying.
C1215 Mesh Cleanser
is a mesh preparation product combining efficient de-greasing with uniform wetting of all meshes from coarse to superfine. Essential for enabling even transfer of capillary films, and enhancing the adhesion of film/emulsion and direct systems. Particularly good for removing road haze from the outside of windscreens, just wipe over using cloth moistened with C1215 for a clearer view of the road ahead!
Mesh Prep Liquid
A highly active pre-treatment compound for degreasing polyester, nylon and stainless steel fabrics. It is recommended for use with all types of photo stencil systems.
SunCoat Degreaser Concentrate
A highly active pre-treatment compound for degreasing polyester, nylon and stainless steel fabrics, either by manual application or in automatic reclaiming/cleaning machines.
ULANO MESH TREATMENT PRODUCTS
Mesh Preparation Products
No23 Roughening / Degreasing Gel
An abrasive degreaser gel that combines the actions of No2 & No3 products. The abrasion of the mesh promotes better wetting of the fabric and adhesion of stencils of all types.
No25 All Mesh Prep
A ready to use liquid mordant that promotes mesh water retention and thus uniform adhesion of capillary films
STENCIL PRODUCTION
Here are some of the many emulsions available from Suncoat, Murakami and Ulano. There are many more for specialised applications available. Please ask if you have specific requirements
Suncoat Emulsions
Horizon Emulsion
Suncoat Horizon emulsion is a dual cure product with high solids content, capable of producing stencils of the highest quality. It should be used where high definition and resolution are required. It is suitable for most solvent and UV ink systems including most water based products
2000 Emulsion.
Easy to use, high solids content, fast exposing, dual cure emulsion with excellent latitude, edge definition and resolution.
Universal Graphic
A presensitized one component photo-polymer emulsion used for the production of highest quality screen printing stencils.
Vista Plus
A dual cure emulsion capable of product photo-stencils of an extremely high quality, it should be used where high definition and resolution are required and is recommended for four colour process printing.
Murakami Emulsions And Films
Murakami One Pot C2 Emulsion.
Replaced by ;
Murakami One Pot WR Emulsion
One Pot WR is a PVA – SBQ patented pure photopolymer direct emulsion. specially formulated for waterbased solvent based and UV ink systems. A similar high specification emulsion to Type C which it replaces, it produces excellent high quality stencils with superlative edge definition.
Murakami MSP-2 Emulsion.
MSP-2 Emulsion is a pre-sensitised one component emulsion for the production of high technology stencils and can be built up to more than 900 microns above the mesh. It is eminently suitable for use in automatic coating machines.
Murakami Capillary Films.
Murakami manufacture pure photopolymer capillary and capillary / emulsion films. These are non shrink and reproduce the finest detail. The nature of a capillary film allows precise control of ink deposit ensuring the highest definition. The 20-100 micron films produce the finest detail as demanded by electronic component manufacture. The range of MS Thick-film are used to produce high deposit prints as used in the garment industry for producing 3D plastisol images.
Ulano Films and Emulsions
Ulano Indirect System Films
Ulano indirect films offer superior fine detail reproduction with sharp printing edges, uniform stencil thickness, easy removal, and predictable exposures.
The range of Photographic Films includes
Pulsar Indirect
Not a gelatine based indirect film, but works like one! Based on photopolymer chemistry. Pulsar develops in water only, not needing peroxide baths (popular benefit!)
Good resolution, high resistance to non-waterbased inks, Removes easily with ordinary stencil strip liquid. If you are into indirect stencils, you should try this!
Ulano Quasar Indirect Film
NEW PRODUCT!!!
A gelatine based indirect film that is virtually a direct substitute for Five Star. Can be directly substituted for Five Star, Same exposure, same development, same application BUT it’s cheaper at list prices!!
Ulano Direct Film Capillary Film System
Ulano CDF films are simple to use, adhere and develop with water only, give excellent mesh bridging . The flat bottomed stencils with consistent thickness and sharp shoulders give excellent definition.
