How to print supper smooth glossy silicone effect?

Key points for HD Glossy Silicone Ink Screen Printing

1st To make a thick screen

 2nd For the hairy fabric, to heat press by heat press machine or iron after first-time silicone printing for smooth effect. Silicone ink is sticky when lifting up the screen and heated all fabric hairy will stand up, if heat presses then all fabric hairy will lie flat and get a smooth effect.

First printing can not heat need to keep 100% wet before heat press.

3rd For glossy silicone printing, after printing should wait for bubbles to out, then cure at a lower temp like 100-110 degrees. For glossy silicone can printing 1-2 times, if two times printing can print wet on wet or heat then screen printing again.

Screen printing glossy silicone ink printing process:

Preparation:

1. Mesh&Squeegee: 120(48T) Mesh number; 65-75 degree Squeegee.
2. : Pigments added ratio: For white and fluorescent colors 20%, other colors 10%
3. Catalyst mixing ratio:2% slow dry XG-866B-1 and fast dry XG-866B-2 can mix together for use.
4. Silicone thinner XG-128A adding ratio:0-20%    Silicone thinner is not necessary for hand printing
5. Heating Temp and time: Flash cure temp:100℃- 120℃ for 6-10 seconds, Drying temp:120℃- 140℃ for about 2 -3 minutes.

Silicone ink printing tips:

• 1 HD silicone XG-866A for under-coating  and high-density printing 2-8 times :

HD screen printing silicone     XG-866A        60G

Fast dry catalyst               XG-866B-2           1.2G  2%   If machine printing to use slow dry catalyst.

Silicone thinner        XG-128AH  Silicone thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by the temp of 120℃ 6-10 seconds.

If fabric with hairy or want to get a more smooth effect kindly assist by heat press machine or iron after the first time printing. After printing keeps wet to heat press by temp 150-170 degrees for 10-20 seconds.

• 2 Color effect silicone printing for 3-4 times :

Black color pigment         XG-501           6G For white and fluorescent color 20%, other colors 10%

Fast dry catalyst            XG-866B-2       1.2G  2%  If machine printing to use slow dry catalyst.

Silicone thinner     XG-128AH Silicone thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by the temp of 120℃ 6-10 seconds.

• 3 Glossy silicone ink or matte silicone ink for top coating:

 Glossy top coating for 1-2 times:

Glossy silicone ink   XG-399-3    60G

Fast dry catalyst  XG-866B-2      1.2G  2%  It will be better to use slow dry catalyst XG-866B-1 and fast dry half and half. If for machine printing to use a slow dry catalyst.

Silicone thinner     XG-128AH  Silicone thinner is not necessary for hand printing, 5-10% is enough for machine printing. Cure by the temp of 100-110℃ 10-25 seconds  Has to get silicone bubbles out first, try to use code wind to support and it will be better to use low temp by longer heating time. To avoid bubbles problem.
