MacDermid Autotype Neptune is a high-quality, fast-acting, one-part emulsion that is ideal for textile applications and POP graphic specializations. It is widely resistant to water based and plastisol inks. MacDermid Autotype Neptune is extremely sensitive to light and should only be handled under yellow safelight conditions. Prior to use, it is recommended that MacDermid Autotype Neptune be stirred.
INSTRUCTIONS FOR HANDLING & USE
MacDermid Autotype Neptune is extremely sensitive to light, and should only be handled under yellow safelights.
MacDermid Autotype Neptune Direct Emulsion comes as a pre-sensitized photopolymer emulsion for textile garment and POP applications.
Although you do not need to sensitize your MacDermid Autotype Neptune, you still need to make sure that your mesh is properly prepared. To help you in any mesh prep, Garston offers a number of degreasers and haze or ghost removers to prepare your screens. These include:
Autotype CPS Degreaser Concentrate
Ulano UlanoGel No. 23 Fabric Abrader and Degreaser
Chemical Consultants Enviroclean Natural Citrus-Based Degreaser
Prior to coating, the screen must be cleaned and degreased. MacDermid Autotype Neptune can be coated by hand or by coating machine. For a good coating result on coarse meshes, it is recommended you apply one coat on the underside and another coat be applied to the upper side.
To correctly dry coated screens, place them horizontally, with the squeegee side facing up in dark or yellow safelight areas. It is imperative the drying areas do not exceed temperatures 35°C (95°F). Furthermore, the drying area should be properly ventilated with no humidity.
The proper exposure times are crucial for an exemplary stencil outcome. Due to the variability in types of lamps and conditions, you should conduct an exposure test prior to use. The following exposure time can only be used as a starting point for an exposure test:
For coarser and colored mesh, longer exposure time is required. For finer mesh, shorter exposure time is recommended. Exposure equipment with lower power may require a longer exposure time.
After the correct exposure, the stencil should be developed in cold or lukewarm water not above 35°C / 95°F. Rinse both sides of the stencil until the open areas are clean and all extra unexposed photo emulsion is removed. Soak up addition moisture with an absorbent lint-free cloth and leave to dry in temperature no higher than 40° C / 104° F. Once dry, mask out undesirable areas with Autotype CPS WR-Filler if water-based or plastisol inks are used.
MacDermid Autotype Neptune can easily be reclaimed with a Autotype CPS stencil remover. It is recommended to use a high pressure water spray for proper reclaiming. Soak up additional moisture with an absorbent lint-free cloth and leave to dry in a temperature no higher than 40°C / 104°F. Once dry, mask out undesirable areas with Autotype CPS WR-Filler if water-based or plastisol inks are used.
INSTRUCTIONS FOR STORAGE:
For storage, keep the emulsion in conditions between 3°C (38°F) and 20°C (70°F). The shelf life of MacDermid Autotype Neptune Direct Emulsion is 1 year when stored in the mentioned conditions. Storage conditions with higher temperatures will reduce shelf life.
Extending the Life Of Your Emulsion:
Each time that you use your MacDermid Autotype Neptune, remember to first mix it gently.
Heat and certain temperatures can break down the components of your MacDermid Autotype Neptune over time. You must keep it in a cool area to extend its lifespan.
Keep the lid to your MacDermid Autotype Neptune tight to avoid air or light leaks.
As a general rule, keep track of every use of your MacDermid Autotype Neptune to avoid misuse.
