Micromax 5018 UV Curable Dielectric, Membrane Switch
Type: UV Curable Dielectric
Application: Membrane Switch
Color: Blue
Solids: 100%
Shelf Life: 6 months
MacDermid Alpha Micromax 5018 is a UV curable, solvent-less, screen printable dielectric for encapsulant and crossover applications in rigid and flexible circuits. Featuring fast UV cure, zero VOC, and excellent adhesion to PET and conductors per TDS specifications.
Micromax 5018 is a UV curable, solvent-less, screen printable dielectric composition designed for encapsulant and crossover applications in both rigid and flexible circuit manufacture. The material offers rapid UV cure and excellent processing latitude while maintaining outstanding electrical and physical properties after cure, including excellent crosspatch adhesion to print-treated PET and good adhesion to non-print-treated PET substrates and conductors. It is fully compatible with Micromax 5000 series conductor compositions.
With 100% solid content and a density of 1.28 g/cm³, Micromax 5018 is a zero-VOC material when properly cured. The dielectric is blue in color and requires two prints to achieve maximum circuit reliability. Curing is performed at 40 ft/min in air using a 200 W/in medium-pressure mercury vapor lamp, with a UV dose of 500-1500 mJ/cm². The cured film delivers pencil hardness ≥1H and excellent flexibility with no opens under a 180° crease over Micromax 5007. Available in standard packaging with 6-month shelf life per TDS specifications.
