how to Print Silicone Ink on Waterproof Fabric?
Waterproof fabric printing silicone ink
Preparation:
- Mesh&Squeegee: 120(48T) Mesh number; 65-75 degree Squeegee.
- : Pigments added ratio: For white and fluorescent color 20%, other color 10%
- Catalyst mixing ratio:2% slow dry XG-866B-1 and fast dry XG-866B-2 can mix together for use.
- Thinner XG-128A adding ratio:0-20% thinner is not necessary for hand printing
- Heating Temp and time: Flash cure temp:100℃- 120℃ for 6-10 seconds, Drying temp: 120℃- 140℃ for about 2 -5 minutes. XG- 360Z-3 and XG- 180AB have to bake 10-20 minutes
Silicone ink printing tips:
Special agent for under coating for two times:
A. Crossing linker XG-360Z-3 20G
Crossing linker agent XG-260Z-3B 1G 5%
B. Adhesion agent XG-180A 20G
Adhesion agent harder XG-180B 2G 10 %
Two solutions can chose A or B depends on fabric type,need to do test first.
Cure by temp of 120℃ 10-20 seconds. Need longer curing time than silicone ink.
XG-180AB with better fastness and low cost than XG-360Z-1&XG-360ZB
1st HD silicone for under coating for2-4 times :
HD silicone XG-866A/866AH 30G （Or round silicone XG-866LK-1）
Fast dry catalyst XG-866B-2 0.6G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for hand printing,5-20% is enough for machine printing. Cure by temp of 120℃ 6-10 seconds.
2nd Color effect silicone printing for 3-4 times :
HD silicone XG-866A/866AH 30G （Or round silicone XG-866LK-1）
Red color pigment XG-102 3G For white and fluorescent color 20%,other color 10%
Fast dry catalyst XG-866B-2 0.6G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by temp of 120℃ 6-10 seconds.
3rd Glossy or matte silicone ink for top coating printing
A, Glossy top coating for 1-2 times:
Glossy silicone ink XG-399-3 30G
Fast dry catalyst XG-866B-2 0.6G 2% If for machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by temp of 100-110℃ 10-25 seconds Have to get silicone bubbles out first then heating ,try to use code wind to support and it will be better to use low temp by longer heating time.
B, Matte top coating for 1 time:
Matte silicone XG-866M 30G
Fast dry catalyst XG-866B-2 0.6G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by temp of 120℃ 6-10 seconds.
After printing finish, heat by 100℃ for at least10- 20 minutes. XG- 360Z-3 and XG- 180AB have to bake longer time then can work with special coating materials to get good fastness, to back 20 minutes will be better.
( For some waterproof fabric with migration problem then need print anti-migration silicone for two times after print clear silicone ink :
Anti-migration silicone XG-866F-1 30G
Anti-migration silicone agent XG-866FB 0.6G 2%
Fast dry catalyst XG-866B-2 0.6G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by temp of 120℃ 6-10 seconds.Can not heat to be total1ly dry ,or will easy lead to be layered.)
