Description
We offer photo emulsion that is used for engraving of rotary printing screens. Direct emulsion method with heat curing method is used for these purposes. These emulsions are optimum in quality and highly durable. For use in universal application, blue colored high resolution emulsion is much preferred. Our standardized emulsions have tremendous resistant abilities.


Hand Coating:

  • At each end of the cylinder, round reinforcing rings are ideally inserted and positioned in an up-right manner. At a speed of 50 cm per second, the emulsion is applied evenly with the help of a circular rubber squeegee. Right from the base till the top cylinder, the emulsion is applied with utmost efficacy
  • Additional coats should be done according screen mesh count. Further fast drying between coats takes place at a temperature of 20-30 °c. To make this process successful, a drying cabinet with good circulation is ideal
  • The thickness, quality and size of the circular rubber squeegee should be determined as per the nature of application. An ideal good squeegee has an optimal circumference, material thickness, firmness of the rubber, freedom from crack and dirt
  • Exposure Time: It is recommended that the exposure time is pre-determined; since, the local working condition may vary in terms of light sources, temperature and relative humidity
  • Shelf life: From the date of manufacture, atleast 60 days. It should be stored in dark place at temperature below 30 degree and application packing is 10 Kg. Carboy


Direction for Use:

  • Take 1000ml. of photo emulsion and add 50ml sensitizers
  • Mix thoroughly in a clean container with a glass rod. Allow to settle and allow air-bubbles to escape
  • For better results, keep the mixed solution for 6-8Hrs. and then use it
  • For emergency use filter the mixed solution with 100 mesh, polyester or nylon bolting cloth and use within 1 to 2 Hrs. after settling the air bubbles
  • The emulsion can be diluted with distilled water
  • Protect from light and process in a dust proof room under yellow light
  • Chemical and mechanical resistant to all printing paste after polymerization at 180°till it cured property
