We call it Self-Stick film, but you might call it amazing. SR3000 is a repositionable, self-stick film that does not carry or require a stubborn, messy adhesive—that means no residue clean-up, no complicated handling issues, and no adhesive to apply or over-wash. There’s simply nothing else like it in the marketplace today. The film develops a slight tack after wash-out, but will never feel gummy or sticky.
SR3000 has industry-leading durability and resolution capabilities—you can trust it with half-tone images or ultra high resolution images, for deep etches or fine details, and on flat or curved surfaces. The 3 mil thickness is designed to push the envelope in high resolution designs; you can blast finely detailed images without the worry of pinhole blast-through. Use the 5 mil to achieve a deeper etch or multi-stage carving. You will be thrilled with the results.
Processed SR3000 clings steadfastly to any polished surface, providing an ideal system for creating fine quality engravings on glass, wood, stone, ceramic, granite, marble and soft metals.
From exposing to blasting, SR3000 helps you get it done faster, more efficiently than ever before. It saves you money because it saves you time.
Other exposure systems can work for this process. The exposure system must have a vacuum or compression feature and an opaque mat/pad.
A dark room is not needed for this process; photoresist film is white light tolerant. The photoresist film can be exposed to fluorescent or LED lighting for a limited time. Do not expose photoresist film to direct or indirect sunlight.
Photoresist film will cure when exposed to UV light, even under overcast weather. Develop the photoresist film indoors protected from a window or skylights.
An opaque print is key to producing a photomask. We recommend inkjet printers since you can adjust the print settings to print an opaque print.
A UV approved clear film such as Inkjet film for inkjet printers must use for this process. For laser printers used Laser Film or UV Vellum. Do not use paper to print artwork. Note: Color laser printers and Brother brand tend to not work for this process. If you use a laser printer, the print must be opaque.
It is recommended to use the Rayzist Hand Sprayer for this process. The Rayzist Hand Sprayer provides a pressurized fan spray that is required to properly washout the photoresist film. Most standard sprayers such as a kitchen sprayer will not provide enough
pressure to washout the film.
Photoresist films are designed exclusively for sandblasting applications and cannot be used for chemical or acid etching. There is a thin membrane that holds the design together until sandcarved. The membrane acts as a barrier for acid or chemical etching.
Rayzist produces all photoresist films in USA since 1983.
No darkroom needed.
Use SR3000™ Photoresist Film on multiple materials. Achieve light frosting to deep etching on crystal, glass, natural stone and wood. SR3000™ Self-Stick film provides optional Color Fill application.
Maintains the quality of original halftone or vector images.
Exposure times are quick, 20 seconds exposure on a Letralite Unit™.
The washout process is streamlined for maximum efficiency. Provide a ready to use photomask fast.
SR3000™ Photoresist Film is the most flexible sandcarving film available. Use it on flat or curved or tapered surfaces.
SR3000™ Photoresist Film is a repositionable sandcarving film. Apply SR3000™ photomask to the surface and realign multiple times if needed. Squeegee photomask once in place. Sandcarving is quick since there no layer of adhesive. Peel photomask stencil easy with no residue.
SR3000™ Photoresist Film is designed to be strong and long lasting. Depending on the Mil thickness, SR3000™ can endure Aluminum oxide or Silicon carbide 220, 180, 150 & 120 grit abrasive.
SR3000™ Photoresist Film is available in 3Mil, 4Mil & 5Mil.
SR3000™ Photoresist Film is perfect to achieve a Multi-Stage carve due to the easy peel or removal of the Self-Stick film.
Expose SR3000™ Photoresist Film to printed artwork with Letralite Unit, washout exposed photoresist and dry. Once the film is dry apply to substrate and sandcarve.
Aluminum Oxide or Silicon Carbide is the preferred abrasive to use with SR3000™ Self-Stick photoresist film. The recommended grit size is 120grit to 220grit.
SR3000™ Photoresist Film allows a color fill application after sandcarving. Just leave the photomask on the substrate after the surface is etched and add a spray or hand paint application. Remove the photomask after the paint has dried.
SR3000™ is a UV light sensitive photoresist film. Sunlight will overexpose the SR3000™ film. SR3000™ can be handled under fluorescent lighting for a limited time or under yellow lighting with no limitations. SR3000™ is a water-soluble film.
A - The SR3000™ is a light sensitive film. Do not wash film outside, indirect or direct UV light will expose film at a fast rate.
B -Wash film with Rayzist hand sprayer which produces a pressurized fan spray. Pressure is important for developing film. Rayzist hand sprayer recommended distance is 1 - 2” from exposed film.
C - Confirm you have a dark opaque print.
D - Exposure time on a Letralite™ unit is 20 seconds and Luminex 1422 exposure unit is 6 seconds.
A - Hold your print up to light and confirm no light is passing through. If light is passing through double check your print settings to ensure you have the darkest print setting possible.
B - Color laser printers are not recommended as they often do not print a true black.
A - If the SR3000™ stencil/mask feels dry, reactivate the adhesive by applying the mask to a damp lint free cloth.
B - Apply Cover Paper (backing paper) SR3000™ photoresist stencil/mask once the sheet is dry. This will preserve the self-stick properties.

SR3000™ Photo Resist Film 
This product is the best, I used all the time to etch wine bottles, never had have any problem.
Fantastic product, easy to work with. Makes all our sandblasting projects much easier to blast. We have used 3 mil, 4 mil and 5 mil, when you have such a great product it makes our work effortless.
The customer service is amazing too. Thanks Rayzist !!! So happy to have found you for our 2034VXA SAND CARVING SYSTEM and sand carving products.
PS Liz 10 stars… !!
Great product, easy to use.
I am new to sandblasting and ordered this as my first venture. I was told it is the best material. I currently do laser engraving and am trying this on it.
Great product–easy to us. Our shop uses the 4 mil and heavier weights as well for deeper etchings. We appreciate the knowledgeable and helpful staff.
