How to Print HD Screen Printing Silicone?
High Density Silicone Ink Screen Printing Process
Preparation:
1.Mesh&Squeegee: 120(48T) Mesh number; 65-75 degree Squeegee.
2.: Pigments added ratio: For white and fluorescent color 20%, other colors 10%
3.Catalyst mixing ratio:2% slow dry XG-866B-1 and fast dry XG-866B-2 can mix together for using
4.Thinner XG-128A adding ratio:0-20% 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 -5 minutes. Glossy silicone heating to use lower temp 100degree is enough, higher temp may lead to bubbles problem.
Silicone ink printing tips:
1st.HD silicone XG-866A/866AH for under-coating and high-density printing for 2-8 times :
HD silicone XG-866A/866AH 100 G
Fast dry catalyst XG-866B-2 2G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH 10G 10%
Cure by the temp of 120℃ 6-12 seconds.
If fabric with hairy or want to get more smooth effect, kindly assist by heat press machine or iron after first time printing. After printing keeps wet to heat press by temp 150-170 degrees for 10-20 seconds.
2nd.Color effect silicone printing for 3-4 times :
HD silicone XG 866AH 100G
Red color pigment XG-302 10G 10%
Fast dry catalyst XG-866B-2 2G 2% If machine printing to use slow dry catalyst.
Thinner XG-128AH 10G 10%
3rd.Glossy silicone ink or matte silicone ink for top coating:
A.Matte top coating for 1 time:
Matte silicone XG-866M 60G
Fast dry catalyst XG-866B-2 1.2G 2% If machine printing to use slow dry catalyst.
B, Glossy top coating for 1-2 times:
Glossy silicone ink XG-399-3 100G
Fast dry catalyst XG-866B-2 2G 2% For table printing if need loner printing time, catalyst to use half-fast dry catalyst XG-866B-2, and a half slow dry catalyst XG-866B-1 If for machine printing to use slow dry catalyst.
Thinner XG-128AH thinner is not necessary for table printing,5-10% is enough for machine printing. Cure by the temp of 100-110℃ 10-25 seconds have 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 on machine printing.
Thinner XG-128AH thinner is not necessary for hand printing,5-10% is enough for machine printing. Cure by the temp of 120℃ 6-10 seconds.
After finish, to cure by 120℃- 140℃ for about 2 -3 minutes.
