Thick film stencils using Plus 9000
Thick film stencils can be made using Plus 9000. Plus 9000 is a 47% solids, red, photopolymer, plastisol resistant emulsion.
Coating thick stencils should be done using a round edged trough. The trough should be full and coating should be very slow.
The example above was coated 2+8 wet on wet on 43.80 mesh, turning the frame through 180oC after 4 coats to prevent the emulsion sagging. It was then dried horizontally, print side down at 35oC overnight. It was exposed for 1.5 minutes at 90cm with a 5kW metal halide lamp. It was washout out from the print side using a pressure washer with 20cm fan. The stencil profile achieved was 160 microns with 200 microns resolution.
Thicker stencils can be achieved with more coats for example 2+12 coats gives 280 microns stencil profile.
On a 34.100 white plain weave mesh coated 2+15 wet on wet, exposed for 2.5 minutes [70 units on a 5kW metal halide lamp] a wet stencil profile of 370 microns was achieved, which dried to 325 microns, indicating the wet stencil will be approximately 12% thinner after drying.
