Printers Screen Wash used for attack ink off screens in the screen-printing industry.
Directions
Apply on screens through cloth, brush or by spray technique. Retention time might 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
FOTECHEM 2044
Chemical for Washing SilkscreenSilk Screen Process Stencil Remover Powder
a white, oxidizing powder to can be dissolved in water to create a liquid screen process stencil remover.
Directions for use
• Use this liquid to decoct (reclaim) screen emulsions and polymer films. It does not work on gelatins 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 have been rinsed off with a soft spray.
• For stubborn stencils less water can be added to create the product more efficient and to avoid the use of the power spray.
Application
• To remove stencil emulsions, direct/indirect films plus 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 be relevant a degreaser and rinse with water before the remover fluid is applied.
• Do not let dry the remover liquid on the stencil. Water resistant emulsions need a higher concentration of the remover fluid. Use 5-10 liters of water only to 100 grams of powder.
• Underexposed stencils turn out to be 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 decorated.
• The use of an inadequate light source in relation to the type of emulsion
can cause removal difficulties.
FOTECHEM 2005
FOTECHEM 2005 is a broad paste, ready to use, for the decoating of most stencil materials.
Directions for use
• Brush FOTECHEM 2005 on both sides of the cleaned stencil with a stiff, metal free brush.
• FOTECHEM 2005 paste allows removing all screen emulsions and photopolymer films. The paste is however not effective for the removal of gelatin films (indirect photo films).
• Always clean stencil from ink residues after printing. Then merely 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 every silk screen emulsions, direct/indirect and capillary films on every type 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 degreases 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 emulsions need a longer reaction time than solvent resistant emulsions.
• Under exposed stencils are always more difficult to be decoated.
• It is important that the right cleaning agent is used after printing to remove the ink; otherwise the cleaning agent can render the stencil removal much more difficult.
• Chemically hardened silk screen emulsions cannot be decoated.
• The use of an inadequate light source in connection with the stencil material can cause removal difficulties.
