The L-400, N-400 System provides a slower, more controlled reaction than the L-14/N-28 suite in producing a robust, conductive, and highly-detailed film on photo-resist and other polymer substrates. It is useful for difficult-to-wet substrates and when an extreme degree of accuracy is required. Recommended supplementary solutions: C-22 Wetting Agent & #93 Sensitizer This item must ship as corrosive and is assessed an additional hazmat fee on pints and larger sizes. [/fusion_alert]
