How it Works:
A revolutionary concept in self-stick resist films, SR3000 is NOT
a "self-adhesive" product. That means there
is NO adhesive to apply or over-wash, NO stubborn residue to clean up
and NO
complicated handling issues common with other "self-adhesive"
products. An advanced version of SR2000,
SR3000 has the same basic
photopolymer properties with a new process that gives the surface
layer an inherent tack once developed. SR3000
looks and feels exactly like pre-exposed SR2000.
In other words, prior to development, you will feel no tack at all.
Since SR3000 is not a "self-adhesive" film,
there is no layer of adhesive to wash off. Simply wash it out.
The film becomes tacky after wash out, but not gummy.
Once dry you will detect a slight tack. Apply the film to your
etching product as usual and blast. SR3000
will not come off until you want it too if you follow the process
correctly.SR3000 is a
repositionable self-stick film that will cling to any polished surfaces
such as glass, granite, marble, ceramic and the like. 3 mil is
designed to "push the envelope" in high resolution
designs. Carvers desiring to achieve
a deeper etch or
multi-stage carving will be thrilled with the results of 5 mil.
What's So Good About
Self-Stick?
There are two main advantages by using
SR3000 Self-Stick Resist. First,
it eliminates the adhesive application process. While adhesive
application doesn't actually take much time, the set up to do so can
be an inconvenience for some. Others have
trouble getting the adhesive layer consistently thin and even.
An un-even coating
of adhesive runs the risk of
creating difficult thick spots that
may be harder to blast
through. This of course results in poor quality work and
possibly ruining a
job. Since SR3000 eliminates this process;
results are completely consistent with every use.
Why is Self-Stick Better than
Self-Adhesive?
The primary advantage SR3000
Self-Stick resist has over other competing
"self-adhesive" films is that there is no
adhesive! With self-adhesive
types, the adhesive has been sprayed onto
the surface and then covered with some type of plastic cover sheet.
After exposure,
the protective cover
sheet needs to be pulled away to expose
the layer of sprayed-on adhesive. This
causes handling concerns. First, you have to peel off the clear cover
sheet after exposure and before wash out to get to the wash out layer;
then you have to use caution when handling the adhesive layer
with your fingers. The natural oils on your fingers can diminish the
tack of the adhesive coating. You will also have to wash out your
image effectively without over washing the film, further diminishing
the tack of the applied adhesive. If you do those things successfully,
beware not to allow sheets to touch each other during the drying
process (a hurdle for production users) and thus ruining your sheet.
Any diminish in tack due to the above will weaken the bond of the mask
to the product you intend to blast. There is also the risk that tiny
bits of adhesive remain in fine detailed areas or corners of the image
causing blockage. With SR3000 Self Stick
Resist it's really simple: just expose and
washout (no cover sheet to contend with). In addition, cleaning up
SR3000 is much faster and easier because
there is no stubborn adhesive residue to contend with. With SR3000,
none of these obstacles are a factor; saving you both time and money.
Description/Application :
User friendly SR3000 is a high-resolution photo resist with an
inherent self sticking quality enabling etchers to achieve the finest
detail and deepest etch in the sand blasting industry. SR3000 will
turn any black and white design into a sandcarving stencil. It
provides an ideal system for creating fine quality engraving on
endless varieties of glass, wood, stone, ceramic, granite, marble, and
soft metals. From exposing to blasting, carvers are able to get it
done faster and more efficiently then ever before.
Cost: Prices typically range from 5-7 cents per square
inch.
Exposure Time: 25-35 seconds
Room Lighting: No darkroom or yellow lighting needed. SR3000
photo resist film can be handled in white fluorescent lighting for
approximately ten minutes without effecting the performance of the
film. Avoid any room or area that has direct or indirect UV light
such open windows or doors. Sun light will expose the film in a
matter of seconds.
Development: Standard washout times begin
at 45-90 seconds, depending on the mil.
Durability: SR3000 has unmatched blast resilient
properties superior to any photo resist in the industry. Blast high
resolution designs without the worry of pin hole blast through or
carrier release bubbling.
High Productivity: SR3000
eliminates the problem of "self-adhesive" films such as loss of
tack, stubborn clean up, and hyper-sensitive handling issues.
"Production time is reduced so we make higher profits. We saved
around 30% of our time when etching a run of 100 glasses." *
Mils: SR3000 comes in
3,4 & 5 mil thicknesses.
Requirements: To use SR3000 photo
resist film, you will need a UV light source, film tool, pressurized
washout unit (such as a Rayzistฎ Hand Washer or Automatic Washout
Unit) and
Plastic Burnisher. We
strongly recommend our
Wire Wheel Brush
when using SR3000
Shelf Life: Conservatively, 14 months at room temperature.
Material Chosen and Why: SR3000
photo resist film
satisfies all needs for a self-stick film without
the problems "self-adhesive" brands can bring. SR3000
renders unmatched detail for half-tone imaging and ultra high
resolution images. SR3000
saves time and money by enabling you to produce a superior product
with less hassle.
