Latest NewsLow temperature curing laser engraving silver paste ( Model: MGT-LEP-S518 ) is suitable for a new type of capacitive touch screen laser engraving , in a variety of substrates ( including AgNW transparent conductive film ) have excellent printing, electrical conductivity, adhesion and with very good mobility and levelling property. The printing thickness can be controlled in 4-6um, it can meet the application of 30um thin line laser etching.
Product features：
1. Fine Engraving Performance ( line width/Space，L:30μm,S:30μm )
2. Low Temperature Curing ( Circulating Heat /IR Curing , ITO/PET Film:130℃*10min,
Glass:150℃*7min )
3. Excellent Substrate Compatibility（PET、Glass、ITO、etc….）
4. Excellent Electrical Performance ( Volume Resistance ＜5.0×10-5 Ω.cm )
5. Customized product can meet the differentiated applications.
