Resists & Coatings


Resists & Coatings

A resist masks a surface partially with a certain design or coves it all over before finishing, further processing or transporting the material, i.e. it protects a surface against external influence. Applications such as etching, sand blasting, sputtering and selective brushing of metal surfaces are in the focus of the sales programme.

A new and technically interesting area, which opens up many possibilities.

Transfer method
KIWOMASK UV 7322 VP
UV-curable Resist for selective brushing of metal surfaces, partial sandblasting and for masking surfaces prior to sputter coating. (PVD).

KIWOMASK UV 7322 VP stands out with its very good printing and good cross-linking properties. After cross-linking using a UV light source, the surface is non-sticky and has high mechanical resistance. After partial surface treatment, the resist can be very easily removed either with a solution of 2 – 5 % sodium hydroxide or 3 – 7% sodium carbonate, as well as simply with water.

KIWOMASK UV 871
UV curing resist for selective etching and brushing of metal surfaces, e.g. for the production of vehicle interior parts or industry signs.

Besides very good mechanical resistance, KIWOMASK UV 871 is also resistant against acidic etching processes (e.g. ferric(III) chlorid). Excellent printing properties facilitate a sharp-edged print of finest structures. Cross linking by UV light provide short processing cycles without drying time. Aside from the common stripping methods with slightly alkaline stripping products, it can be removed with hot water (60 ° – 80 ° C / 140 ° – 175 ° F).

KIWOMASK W 857
Screen-printable resist with high mechanical resistance for selective brushing of metal surfaces.

The thixotropic formulation permits sharp-contoured prints of the finest structures. KIWOMASK W 857 is easily removable with butyl diglycol, or solutions of soda, natron and potash (3–5 %), as well as the ready-to-use PREGASOL R 800.

KIWOMASK Z 865/2 VP / Z 865/3 VP
KIWOMASK Z 865/3 VP is both a screen and tampon printable etch and galvano resist for glass and metal surfaces.

This product series has very good resistance to acidic and alkaline solutions in etching and galvano baths, as well as to solutions containing hydrogen fluoride (HF). The resists are ready to use, but may thinned or retarded with KIWOSOLV L 14. KIWOMASK® Z 865/2 VP is the faster drying version of KIWOMASK Z 865/3 VP.

[Translate to English:] KIWOMASK W 850 Etch
Thermically curable sputter resist for glass surfaces.

KIWOMASK W 850 Etch is suitable for physical, vacuum-based coating processes (PVD, magnetron sputter coating) and comes with a good resistance to aqueous cleaning processes. Stripping can be done with soda, soda or potash lye (3 – 5 %), with mild organic solvents (e.g. KIWOCLEAN LM 606) or the ready-to-use solution PREGASOL R 800.

KIWOMASK IJ 510
Resist for decorative sputter coating of architectural glass.

KIWOMASK IJ 510 is applied to the surface to be coated using a flatbed digital printer for solvent inks. The resist masks the areas that are not sputtered. After the coating process, the resist can easily be removed in a manual or mechanical cleaning process with KIWOCLEAN LM 606.

 

KIWOMASK UV 160/2
UV-curing sandblasting resist for metal, natural stone, ceramics and glass surfaces.

Besides good sandblasting resistance, KIWOMASK® UV 160 / 2 is also resistant to water and organic solvents. Can be easily removed as film. The transparent blue colouring (greenish / yellow after UV cross-linking) offers a good contrast to control print quality, however, at the same time enables the recognition of overprinted designs.

KIWOMASK UV 161
UV-curing protective film for plastic, glass or metal surfaces, e.g. displays, membrane keyboards, operating elements or speedometer discs.

KIWOMASK UV 161 protects surfaces during further processing steps, such as subsequent printing, cutting, punching or deep drawing processes. Resistant to water and organic solvents. Can easily be removed as film.

KIWOMASK S 110 / S 111 Colourless
Screen-printable, “liquid” protective film for partial or full surface protection of sensitive surfaces against mechanical stress during further processing or transportation.

Resistant to organic solvents, KIWOMASK S 110 is water-based and can be cleaned either with water or easily removed after drying as a film. It is also available in the colourless version as KIWOMASK S 111 Colourless.

KIWOMASK S 112
Screen-printable and removable protective film based on aqueous polymers.

After the application by screen printing and drying, KIWOMASK S 112 protects component, especially plastic film, against mechanic damage.

KIWOMASK S 150
“Liquid” protective film for partial or full surface protection of sensitive surfaces.

The transparent blue colouration allows detection of over-printed designs. KIWOMASK S 150 is also suitable for the protection of plastic films, which are deep-drawn after the printing process.

 

KIWOMASK W 128
“Liquid“ protective film which can either be applied over a large area or partially coated onto the surface to be protected.

KIWOMASK W 128 is colourless, water-based and can be diluted with deionized or distilled water to adjust viscosity. After drying, it is water resistant and very resistant to mechanical stress. For instance, applied as a temporary protection onto scratch-sensitive surfaces (such as glass, metal and various
plastics) prior to further processing steps. It can be dyed black colour by adding MECOCOLOR AF Black and be easily removed as a film again.

KIWOMASK W 122 Colourless
Easily removable “liquid” protective film for the all over protection of glass, plastic metal and other scratch-sensitive surfaces.

KIWOMASK W 122 Colourless is colourless, water based and can be reduced with deionized or distilled water. After drying, the resist forms a flexible, water resistant and easily removable protective film. Also available as low viscous, white version KIWOMASK W 120.

KIWOMASK S 7318/1 VP
Transparent, “liquid“ protective film for coating scratch and contamination sensitive surfaces, e.g. for protecting against spray mist in lacquering booths.

Due to its transparancy, KIWOMASK S 7318 / 1 VP is very suitable for a protective coating of vision panels or non oxidizing metals, galvanized, lacquered or powder-coated metals or plastic surfaces. KIWOMASK S 7318 / 1 VP is water based and comes ready-to-use for spraying, dipping or applications. Can be reduced with deionized or distilled water, if necessary. Forms a solvent resistant and easily removable protective film after drying. KIWOMASK S 7318 / 1 VP is water soluble also after drying and can be removed with water.
