Screenwash

Degreasing, Cleaning, Blockouts & Emulsions for Screen PrintingPrinters ScreenWash used for cleaning ink off screens in the screen-printing industry.

Directions
Apply on screens with cloth, brush or by spray method. Retention time may vary with type and amount of ink or emulsions used on screens. Then wash the screens off with high pressure water.

  • Environmentally safe
  • Biodegradable product
  • No Harsh Chemicals

Screen Cleaning Chemicals

FOTECHEM 2044
Screen Process Stencil Remover Powder
A white, oxidizing powder that can be dissolved in water to make a liquid screen process stencil remover.

    Directions for use
  • Use this liquid to decoat (reclaim) screen emulsions and polymer films. It does not work on gelatine films.
  • Clean stencil from ink. Then brush on the liquid from both sides. Let stand for the necessary time. Hose off with a hard cold water spray. Better is the use of a power spray after the chemical has been rinsed off with a soft spray.
  • For stubborn stencils less water can be added to make the product more efficient and to avoid the use of the power spray.
    Application
  • To remove stencil emulsions, direct/indirect films and capillary films from all meshes. After printing the stencil must firstly be cleaned from all ink residues before they dry in. To speed up the removal, it is recommended to apply a degreaser and rinse with water before the remover liquid is applied.
  • Do not let dry the remover liquid on the stencil. Water resistant emulsions need a higher concentration of the remover liquid. Use 5-10 liters of water only to 100 grams of powder.
  • Underexposed stencils become considerably more difficult to remove. If the wrong ink or an inadequate cleaning agent is used (in relation to the type of emulsion or film), the removal can become difficult.
  • Chemically hardened emulsions cannot be decoated.
  • The use of an inadequate light source in relation to the type of emulsion
    can cause removal difficulties.

Stencil REmover StripperFOTECHEM 2005
FOTECHEM 2005 is a thick paste, ready to use, for the decoating of most stencil materials.

    Directions for use
  • Brush FOTECHEM 2005 onto both sides of the cleaned stencil with a stiff, metal free brush.
  • FOTECHEM 2005 paste allows to remove all screen emulsions and photopolymer films. The paste is however not effective for the removal of gelatine films (indirect photo films).
  • Always clean stencil from ink residues after printing. Then only apply the paste. Let stand or continue to brush. Then spray out with water. Recommended is the use of a high pressure device; important is to rinse the chemical off with the soft water spray before the high jet gun is operated.
    Application
  • FOTECHEM 2005 paste can be used for the removal of all screen emulsions, direct/indirect and capillary films on all types of meshes.
  • Important is that the ink residues are removed completely after printing and before they dry in. Use the adequate solvent. To speed up the removal action degrease the stencil after cleaning with a commercial degreaser, then rinse before applying the FOTECHEM 2005.
  • This paste should not dry in on the mesh. Water resistant screen emul sions need a longer reaction time than solvent resistant emulsions.
  • Under exposed stencils are always more difficult to be decoated.
  • It is important that the correct cleaning agent is used after printing to remove the ink, otherwise the cleaning agent can render the stencil removal much more difficult.
  • Chemically hardened screen emulsions cannot be decoated.
  • The use of an inadequate light source in connection with the stencil material can cause removal difficulties.

Haze Remover

ASPS Haze Remover has been specially formulated for the Screen Printing Industry to completely remove most types of ink images that may remain after the emulsion has been removed.

Directions
Apply neat with a brush or rag, rub it on both sides of the screen and allow it to crystalize (dry). Reactivate the screen with our environmentally friendly Screen Wash Extra and hose with high pressure water.

  • Completely cleans and removes residual ink stains.
  • Low odour
  • Low in VOC

Screen Degreasing

FOTECHEM 2033
Concentrate (add to 10 litres of water to 1 Litre 2033)

Is an identical product to FOTECHEM 2003 but supplied as a concentrate to allow the screen printer to prepare an adequate degreasing solution.  

FOTECHEM 2023
Combined abrader/degreaser gel, ready-to-use.

Is a slightly alkaline abrasive/degreaser gel to promote better wetting of the fabric and improved adhesion of all types of stencils, especially on new mesh. FOTECHEM 2023 is a slightly alkaline abrasive/degreaser gel to promote better wetting of the fabric and improved adhesion of all types of stencils, especially on new mesh.

    Directions for use
  • dampen the screen fabric with water
  • apply from both side with a stiff nylon brush
  • let the screen stand a few minutes
  • rinse thoroughly from both sides with warm or cold water

* FOTECHEM 2023 roughens the mesh slightly, therefore it should be used mainly on new polyester or nylon mesh and not on multifilament synthetic fabrics. It can also be used after stencil removal to help eliminate emulsion and ink residues. But each application increases the roughness of synthetic monofilament fabrics.


Screen Emulsions

EMULSIONS FOR PRINTING ON TEXTILES

ASPS has a wide range of water resistant and water/co-solvent resistant screen emulsions.

  • An individual TECHNICAL INFORMATION sheet is available for each product.
  • When printing plastisols, use white spirit only or similar soft solvent for wash-up (cleaning) in combination with the FOTECOAT emulsions listed below. If stronger solvents are used, choose from our range of solvent resistant emulsions.
