Short shelf life once sensitized (6-8 weeks, up to 3 months if refrigerated).Can be exposed to UV light while wet without curing so you can coat screens in normal lighting (though not recommended).Forgiving exposure latitude over or under exposing your image.Durability over long print runs (10,000+ pieces).Holds good high detail due to the finely ground particles in its make up.If you’re not using a water resistant formulated dual cure emulsuion and plan to print water base ink you may need to apply a hardener after rinsing out your stencil to avoid breaking the emulsion down on press when ink is applied. Out of the bucket, Dual Cure emulsions are also generally appropriate for plastisol or solvent inks. They generally require a longer exposure time. Dual cure emulsions have a medium solids content that results in a thinner product that will require more coats be applied to achieve a thicker micron. Dual cures utilize some of the straight diazo and some of the photopolymer properties. This means a photo-sensitive additive must be mixed into the emulsion before it can be applied to screens for exposure. We won’t get into diazo emulsion here as manufacturers are phasing out this type of product.ĭual Cure emulsion is a (diazo) direct emulsion that is not pre-sensitized. There are two basic categories of direct emulsion dual cure and photopolymers. It can be applied to both the ink and substrate sides of the mesh in multiple layers to achieve a stencil micron specific to the substrate the screen will be used to print.
