Latest NewsLow temperature curing laser engraving silver paste ( Model: MGT-LEP-S930 ) is suitable for a new type of capacitive touch screen laser engraving , in a variety of substrates (especially for silver nanowires transparent conductive film, AgNW TCF ) have excellent printing, electrical conductivity, adhesion, and with very good mobility and levelling property, the thickness of the printing can be controlled in 5 to 7um, it can meet the application of 30um thin line laser etching, and it's more suitable for the application of silver nanowires transparent conductive film at low temperature curing.
Product features：
1. Fine Engraving Performance ( line width/Space，L:30μm, S:30μm )
2. Low Temperature Curing ( Circulating Heat /IR Curing , AgNW TCF: 90℃*30min ,
ITO/PET Film:130℃*30min )
3. Excellent Substrate Compatibility（AgNW TCF、PET、ITO、etc….）
4. Excellent Electrical Performance ( Volume Resistance＜7.0×10 -5 Ω.cm )
5. Customized product can meet the differentiated applications.
