Grafic HU by SaatiChem® is a versatile dual-cure direct emulsion designed to meet the high demands of general and specific graphics printing applications. Part of the GRAFIC family, this emulsion is formulated to deliver exceptional print definition, stencil resolution, and durability. Whether you’re working with UV-cured, plastisol, solvent-based, or water-based inks, Grafic HU ensures consistent, high-quality results across various substrates.
Grafic HU features a controlled particle size that guarantees excellent print definition on any mesh, making it an ideal choice for a wide range of screen printing tasks. Unlike typical dual-cure emulsions, Grafic HU dries to a smooth, tack-free finish, ensuring your stencils are ready for precise printing without any unwanted adhesion.
This emulsion is particularly well-suited for applications such as ceramic decals and direct printing on ceramic tiles for third firing, where precision and durability are critical. With a high solids content and medium viscosity, Grafic HU produces low Rz stencils that offer superb print definition, even on the finest meshes.
Key Features:
- Versatile Use: Suitable for UV-cured, plastisol, solvent-based, and water-based inks.
- Controlled Particle Size: Ensures excellent print definition on any mesh.
- Tack-Free Drying: Stencils dry smooth and tack-free, avoiding common issues with dual-cure emulsions.
- High Solids Content: 39% solids content for low Rz stencils with high-definition prints.
- Easy Reclamation: Emulsion is easy to reclaim, making it practical for repeated use.
- Fast Exposure: Features a fast-exposing formula with a wide exposure latitude, suitable for various exposure setups.
- Application-Specific: Ideal for ceramic decals and direct ceramic tile printing, providing high durability in demanding conditions.
Application Instructions:
- Sensitizing & Mixing: Prepare the diazo sensitizer according to the bottle instructions. Mix thoroughly with the emulsion until smooth, then let the mixture stand to allow air bubbles to escape. Use the sensitized emulsion within one month for optimal results.
- Coating: Apply one or two coats to the substrate side of the screen using a high-quality scoop coater, followed by one or two coats on the squeegee side.
- Drying & Storage: Thoroughly dry the coated screen in a dust-free, dark or yellow light area at a maximum temperature of 104°F (40°C), with the substrate side facing down. Store in a safelight environment and use within one month.
- Storage: When sealed and stored in cool conditions, Grafic HU will maintain its original properties for one year from the date of production.
