Photographic Emulsion UNIFILM 3D-SOLV
UNIFILM 3D- SOLV – pre-sensitized photopolymer emulsion. For thick prints with plastisol and solvent based inks. Short exposure time. Ideal for thick stancils on coarse meshes. Good definition. Easy to reclaim.
UNIFILM 3D – Photographic Emulsion
Product: photopolymer emulsion
Application: For the preparation of thick stencils for the textile and ceramic industries.
Application: For the preparation of thick stencils for the textile and ceramic industries.
Properties:
→High definition: Provides sharp edges that are independent of the fabric structure, even for coarse meshes.
→High definition: Provides sharp edges that are independent of the fabric structure, even for coarse meshes.
→Extremely short exposure time: Thanks to this new and exclusive photopolymer technology, the exposure time is very short even with thick stencils. With Unifilm 3D, the time required for correct exposure is about ten times shorter than a stencil of the same thickness made with a traditional diazo emulsion.
→High solid content: With almost 55% solids, the amount of water is low. Because of this, there is a low thickness loss during the drying process.
→High viscosity: During the coating operation, the UNIFILM 3D emulsion does not run down or drip, allowing the use of wet on wet coating technique. All the coating is done in one operation, without the need for intermediate drying, coating or laminating steps.
→Not sensitive to heat: unlike emulsions sensitized with diazo, the UNIFILM 3D emulsion can be dried in temperatures up to 140F (60C) without any negative effect on the photographic properties. Fast drying periods are possible due to this property.
→Pre sensitized – pure photopolymer formulation: The emulsion is ready to use. There is no need to add diazo or to wait for the disappearing of the air bubbles generated in the process of sensitization.
→Long print runs: During the coating process the emulsion penetrates in the fabric structure. Compared to capillary films it provides superior mesh adhesion and consequently longer print runs.
→Fast process for the preparation of thick stencils, providing up to 1800m (70 mil) in a single step process. There is no need for several drying cycles nor over laminating capillary films.
→Compared to the competitive products and techniques available, UNIFILM 3D provides the best results with a simple, easy and repeatable process, at a more economical cost.
