Description
BENEFITS
- Since Baselayr Long Lasting is a user-friendly emulsion, new printers and individuals with DIY darkrooms can use this emulsion and see amazing results.
- The emulsion works for both water-based and plastisol inks, so printers do not need to have several different kinds of emulsions stocked.
- Its high solids formula strengthens the emulsion's adhesion to the mesh, providing better on-press longevity.
Elevate your darkroom with Baselayr Long Lasting Emulsion. It’s a high performance, high solids, dual cure emulsion designed for printers who are either new to screen printing, do not have a proper light safe darkroom, or do not have an LED or better exposure unit. The emulsion works with water-based and plastisol ink types — the dominant ink types on the market today.
Formulated with both novice and advanced screen printers in mind, burned images will rinse out effortlessly and screens will reclaim easily when the stencil is properly dried and exposed. Baselayr Long Lasting will work with virtually all exposure units. Specifically created to be user-friendly, Baselayr Long Lasting is an emulsion all printers can rely on.
If WBP, RXP, or DCM emulsions were in your darkroom, transitioning to Baselayr Long Lasting will be easy. Featuring the same emulsion properties you like, Long Lasting has everything you need in one emulsion. Better yet, the image resolution is enhanced.
NOTE: This emulsion comes with a bottle of Diazo. Diazo must be added to the emulsion for it to work. Details on usage below.
RECOMMENDED
When using light sources like fluorescents, black light, halogen, or off the shelf LED flood lights etc, use Baselayr Emulsion Prep — a screen mesh degreaser and adhesion promoter. The product will assist you in creating a more receptive surface for the emulsion to adhere to.
FEATURES
- Resistant to all water-based ink systems.
- No emulsion hardeners needed.
- Durable enough for print runs using aggressive water-based and discharge ink systems.
- Holds great detail while printing.
- High solids concentration allows for superior bridging of mesh.
- Uses diazo, which enhances detail resolution.
- Color: Magenta
- Shelf Life: With Diazo: See below.
- Add the appropriate amount of distilled water. Do not use tap water. Tap water contains minerals that can interfere with proper adhesion of the emulsion to the mesh.
- It’s important to note that diazo is sensitive to heat. Where you store diazo-mixed emulsion will make a difference to its shelf life:
- If kept in a cool environment around 40° (in a refrigerator), you can extend your shelf life to ~12 weeks.
- The hotter your environment is, the faster the diazo will break down. At 90°-100°, mixed emulsion has a pot life of ~1 week. At 70° it's ~6 weeks.
INSTRUCTIONS
- For quarts, add 25%-50% of distilled water to the bottle of diazo. For gallons, add 50% to 75% of distilled water to your bottle of diazo. Do not use tap water. Tap water contains minerals that can interfere with proper adhesion of the emulsion to the mesh.
- Shake the container, completely dissolving the diazo into the water.
- Add mixed diazo to the container of Baselayr Long Lasting.
- Carefully stir in the diazo completely.
- Let sit for a couple hours to let the air bubbles settle out.
- Apply emulsion to a clean, degreased, and dried screen mesh with a scoop-coater using appropriate application techniques. Try using Baselayr Emulsion Prep, a screen mesh degreaser and adhesion promoter, whenever possible. Depending on your screen and stencil thickness needs, use either the sharp edge or round edge of the scoop coater, coating once or twice per side. More coats means a thicker stencil. Be sure to rotate the screen so that you are pushing the emulsion from both sides to bond around the knuckles of the mesh. Experiment to find what works best for you within your shop.
- Allow your freshly coated screen to dry, shirt side down.
- Expose your screen with the recommended light source. As with all emulsions, test for appropriate exposure time for your unit before exposing your design. Use a Step Wedge Calculator to determine the proper amount of time required to fully cure your stencil. If needed, you can harden your stencil by post-exposing it (make sure the stencil is completely dry like a fresh screen), putting it back in your exposure unit and exposing for 3x the initial exposure time. You can also place your screen in direct sunlight.
- Reclaiming Baselayr Long Lasting is easy and works with most stencil removers or reclaimers that are available in concentrate and ready-to-use formulas. Follow proper instructions for reclaiming.
EXPOSURE VARIABLES
Exposure variables depend on mesh count, mesh color, stencil thickness and moisture level in the coated screen. Keep humidity levels below 40% at all times. Use a dehumidifier to ensure proper darkroom humidity levels.
- Lower mesh = slower exposure / Higher mesh = faster exposure
- Thicker stencil = slower exposure / Thinner stencil = faster exposure
- More moisture = Under Exposed and difficult to rinse out / Less moisture = proper exposure and maximum detail resolution.
- Yellow mesh = slower exposure and more detail resolution / White mesh = faster exposure
SUGGESTED EXPOSURE TIMES
- Mesh: 156 standard mesh color: white Baselayr V & X Series Unit: 2:20 - 2:50
- Mesh: 230 standard mesh color: Yellow Baselayr V & X Series Unit: 2:00 - 2:30
- Mesh: 156 Hi-Dro / Thin Thread mesh color: Yellow Baselayr V & X Series Unit: 3:50 - 4:20
- Mesh: 230 Hi-Dro / Thin Thread mesh color: Yellow Baselayr V & X Series Unit: 3:00 - 3:30
To further dial in your exposure time, run the Step Wedge test with a Step Wedge Calculator.
HELPFUL HINTS TO ENSURE YOUR EMULSION LASTS LONGER
- Store in a cool area. The emulsion will break down much faster in heat. Keeping emulsion in a fridge can slightly extend its shelf life; however, emulsion that has frozen will no longer work properly and must be replaced.
- Keep the emulsion lid on tight to preserve air and light leaks.
- Gently mix the emulsion each time before use to help extend the life.
- To ensure best results, date the emulsion and keep an extra container on hand once the emulsion is about to expire. Environmental factors such as temperature and humidity can cause the emulsion to expire more quickly.
FREEZE WARNING: When ordering emulsion during the winter, please note that it's possible for emulsion to freeze during transit. Frozen emulsion is unusable. We recommend to plan accordingly when ordering so shipping is uninterrupted and to pull all delivery packages inside the building and store in a warm place immediately.

Wow!
I’ve been using Ulano Orange on my fluorescent exposure unit for a while. This is a game changer. Until I upgrade, this emulsion will be part of our operation. Burn time was quicker and the stencil did it’s damn job. Thanks, guys!

Boom! That is awesome to hear! Once you upgrade your exposure unit, you'll want to try Baselayr Complete :-). Happy Printing!!

Great emulsion
I bought this emulsion by mistake but I wasnt dissapointed. When I read on the container that this stuff is for “new printers”, I was worried, but this stuff is actually amazing. This stuff prints very high resolution and washes out easier than the led specific emulsion I was using before.

Hi Wiliam, Thank you so much for reaching out and sharing your experience with the BaseLayr Long Lasting Emulsion. We love when fate comes into play, what an awesome way to discover a new product you love! Feel free to reach back out with details on how you use the emulsion in your shop!

terrible emulsion
While the screens are in the drying process, after burning in, sometimes this emulsion will seep into the image, ruining it. Now I have to reburn and hope it doesn't happen again. Waste of time and money. Good luck reclaiming this emulsion too. Unless you reclaim your screens immediately, this emulsion will not wash out (yes I use high pressure power washer) and screens will be ruined. Big waste of money. Be prepared to buy more screens. If you do purchase this product, you better read the online instructions for mixing it, if you are unsure. Mixing directions are no longer included with the product, and neither is a stir stick. So you may also want to run to your local paint store to get some stir sticks. I've printed for many years and have never had the problems that I've had with this. Please bring back WPB!!!

WHOA! Mark over here with some awesome pictures of some RAD print work. Awesome job Mark, glad you took the dive with the BaseLayr and love it! We hope its a LONG LASTING LOVE ;)

Maybe I received a bad batch
OMG! I have never had any issues with exposure times and washing the images off. I have tried different exposure times, using Ryonet exposure calculator, and it will take forever to wash, I even tried with a solid image using a 110 screen and same issue. I love Ryonet RXP Dual Cure Emulsion and this is nothing similar. Pls bring Ryonet RXP Dual Cure Emulsion back!!
