Rubber Binder for Automatic Rotary Printing Machine Patent ProductRubber Binder 301 Series

1) Summary :Rubber Binder 301 Series are waterbased binders specially designed for Automatic Rotary(Carousel) Printing Machine, so called waterbased plastisol inks, and the Series consist of White301 W-10, Mat 301M-3, and Clear 301C-9.The ordinary waterbased Rubber Binders have some difficulties during a process on AutomaticRotary (Carousel) Printing Machine such as screen clogging, viscosity increase of inks by heatand particularly the ink build-up on a screen bottom during wet on wet print.The 301 Series can prevent these problems. They can be used for a long-time continuousprinting operation with much less screen-clogging and ink-build-up on a screen bottom.Moreover, they can obtain soft handfeel and excellent fastness without tackiness on the printsurface.Rubber Binder 301 Series are eco-friendly products without containing formaldehyde, APEO norMineral Spirit, and it is certified by Oekotex Standard 100 (N-KEN12102); so called ECOProducts.2) Nature :

3) Use & Application of eachI) White 301W 10 High coverage rubberized white paste to be used as under layer ofthe whole design to cover the ground fabric color. This also can be used for half-toneprinting by high-mesh dots screen.II) Mat 301M 3--- The coloring paste to be mixed with Neo Colors (waterbased pigment).Mat 301M-3 can be used for opaque prints on color fabric, so called matte print.III) Clear 301C-9 The coloring paste to be mixed with Neo Colors. Clear 301C-9 givesa brilliant and vivid shade on white fabric.

4) Usage :Applicable Material : T-shirt, Sweat shirt,Cotton, Cotton/Polyester blended knit and woven.Example Recipe :

White 301W-10 100 - -Clear 301C-9 - 100 -Mat 301M-3 - - 100Neo Color (each color) 10 10 10Fixer N (or Fixer F) 2-3 2-3 2-3 (Cross-linking agent)Total 113 113 113 Please refer to our color chart for color matching.

N.B. Additional Fixer N (or Fixer F) is a must. To increase the fastness, perform baking through conveyer dryer 2 times. To increase the viscosity of the inks, add the following auxiliaries into each ink and mixwell evenly before use. Emacol R-530 1 3 %Emacol R-600E 0.51.0 % To reduce the viscosity, use Catalyst 3000 0.5 2.0 %. When Fixer N is mixed, the leftover ink after printing may be sealed and stored in cool &dark place. However, when Fixer F is mixed instead, the whole paste must be used up within12 hours. Dont use the leftover inks. Do not leave the drum opened to avoid the ink surface getting dry. Keep sealed and store in cool and dark place for storage.

The above information is based on our lab. condition.Pre-test is strongly recommended before actual use.

Printing Manual of Rubber 301 Series for Automatic Printing Machine

1) Start printing only when the table temperatere reaches 60or higher.2) Screen Mesh (Recommended) :

White 301W -10 : for White Underbase 120 250 mesh (/inch) [47 98 mesh (/cm)]for color print 120 300 mesh (/inch) [47 120 mesh (/cm)]

Clear 301C-9 : 120300 mesh (/inch) [47 120 mesh (/cm)]Mat 301M-3 : 120300 mesh (/inch) [47 120 mesh (/cm)]

In case of Half-Tone printing, adjust the mesh maximum of 300mesh and the designresolution 45 65 Lpi (line per inch).Screen mesh tension should be tight, must be higher than 25N.

3) Squeegee & stroke Hardness of squeegee: 60 70Print: 1 stroke x 2 times

4) When the squeegee stops, keep the screen flooded.5) Pressure of SqueegeeWhen color inks are being printed on top of the under-white, the screens might makepopping noise when they are released from print surface. In case such noise occurs,reduce the squeegee pressure of the color inks while running the machine.6) Flash drySet the dryer temperature at the highest possible.

Example Process< Example 1 : With White Under Base >

Setting Pre-heat up to 60 or higher White 301W-10

Flash dry White 301W-10 Flash dry

Color print Wet / Wet Removing fabric Conveyer dry

< Example 2 : Direct Print >

Setting Pre-heat up to 60 or higher Color print

Color or White print Wet / Wet Removing fabric Conveyer dry

* N.B.) The printing must be started immediately after pre-heating the pallets. All theadjustments such as screen registrations and squeegee pressures must be done beforepre-heating the pallets.
