To return the goods please make sure they are unused and sealed Exposure Tips Guide is included A scoop coater is recommended for applying emulsion make sure emulsion is dry before exposure Thick coatings of emulsion will not dry well light source must emit UV light - LED is not recommended unless it is UV LED weak bulbs will result in underexposure and emulsion washing off Emulsion will wash off if Exposure time is too short Applying Emulsion to your screen - a scoop coater is recommended to get even coatings Scoop Coater filled with Emulsion We recommend using a scoop coater to apply the emulsion so that you can get an even coating that is not too thick. Thick emulsion will not dry easily. Removing excess emulsion from the screen after coating is best, the mesh will only hold a certain amount. A scoop coater is a very good investment and will help you get better results. Coat both sides of the screen Put enough emulsion into the scoop coater to coat the whole screen. Start with the side of the screen that will go onto the fabric you are printing onto, hold the screen vertically and tilt the screen at an angle, tilt the scoop coater towards the mesh, it will pool against the mesh, pull the scoop coater upwards and coat the mesh. Do this to the other side of the screen. Remove excess emulsion Once both sides are coated pull the coater along the screen again and scoop off excess emulsion. The final side that you scoop emulsion off should be the side that gets the ink, this way you push emulsion towards the print side of the mesh. Drying coated screens Once coated, your screens need to dry flat in a dark, dust free, warm place. ​ Away from light - The mixed emulsion will be light sensitive so it needs to dry in a dark room or cupboard. ​ Temperature - room temperature or slightly warmer is ideal. Dust and dirt - Make sure the area you are coating and drying your screen in is free from dirt/dust/hairs Humidity - If a coated screen has been left to dry in a humid environment, it can cause you problems later on. A de-humidifier is ideal to avoid this happening. Place your screens flat to dry, print side down. If you have coated several screens, you can use spacers to stack them flat on top of one another Drying time - I cannot emphasise enough how important it is to make sure that your screens are completely dry before exposing. Signs of the emulsion not being dried for long enough - if after exposure the emulsion is soft, rubbery or pulls off the screen, this is a sign of the emulsion not having dried enough before exposure. Examples of lights and times that customers have given that worked for them - this is a guide and you need to test your own setup. 100W UV LED Floodlight Distance from screen : 35cm Exposure time : 1 minute 25W UV Bulb Distance from screen : 36cm Exposure time : 8 minutes Distance from screen : 40cm Exposure time : 3.5 minutes The Sun Direct Sunlight Exposure time : 40-50 seconds Underexposure Emulsion washes off your screen Most common causes of underexposure are either using a light source which emits too little UV or emulsion that has not been exposed for long enough. This Emulsion will not work well with a plain LED floodlight. Emulsion must be completely dry Using a scoop coater helps prevent thick coatings of emulsion. Thick emulsion will take longer to dry and will also take longer to expose. Meshcount Meshcount affects exposure time. A 43T mesh is coarser than a finer 90T mesh and therefore will hold more emulsion and will need a little longer to expose. Good Exposures - some tips Use a light that emits UV Do not use an LED light unless it is a UV LED light Exposure time is long enough Emulsion is completely dry before exposure Positives are good quality Get in contact with us if you have any problems or need any help. Step Tests - best way to work out your perfect exposure time ! A step test will help work out the right time for exposure for your setup (expose screen in 10 rows) 1. Estimate the screen exposure time 2: Double the screen exposure time estimated in step 1 3: Divide the total number you now have by 10 4: Cover all apart from row 1 with some cardboard or something completely opaque Expose the screen with only row 1 exposed to the light for the amount of seconds you calculated in step 3 Move the cardboard down after the first exposure to allow row 1 and 2 to be exposed and expose for the same amount of time as calculated in step 3 Move the cardboard down one row at a time and expose the screen for the number of seconds calculated in step 3 until you have done all 10 rows. When your exposure is finished you can wash out your screen and see which row cleans out and prints the best. Keep the screen wet and look at the colour of the emulsion. When you see the point that the colour change stays the same, you have found your perfect screen exposure time. Review: Fab emulsion - Great emulsion, first time buying this brand and the pre sensitized kind so was pleasantly surprised. Really easy to apply and exposed in about 6 mins using our LED lamps Review: Fantastic and great shelf life .... Read review - Purchased this back in 2023 and used it once using a metal halide bulb exposure unit. Results were good but never used again. Sat in the shelf since then. However. I now have a 50w LED UV exposure unit and tried the emulsion today 12th March 25. One side emulsion, exposed for 70 seconds and came out perfect. Never had an emulsion work like that before. I usually use Prod Ecran but shelf life isn't very long once mixed so this Flat Fox stuff certainly lasts longer so I'll be using this from now in ## Features - May cause an allergic skin reaction. - Longer shelf life, up to 1 year from manufacture date - One-part, pre-sensitized. No mixing, no diazo required - Exposes approximately 4x faster than typical two-part emulsion - 47% solids and easy to reclaim - Can be used with discharge inks as-is.

Manafacture dates will be added to new batches that are sent in. **Q: Does this last well once opened?** A: Yes, it has a year shelf life. I store mine under the sink between use and it's perfect. **Q: Hi - do I need to use any specialemulsion remover to reclaim a screen after using this, of will normal emulsion remover be OK???** A: Yes. I use Speedball emulsion remover and it works great. Very easy to remove actually. Honestly this emulsion works very well. I usually expose for 6:30 but obvs you’ll have different requirements and environment. **Q: what kind of light do you use? I know a UV light but can't seem to find a good one online** A: I use a 100 W UV LED Floodlight which works really well - if you search on Amazon you should be able to find a few that are pretty similar. The important part is to get a UV LED light and not a plain white LED one, mine is 100W and it really exposes the emulsion well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fab emulsion *by K***N on 17 June 2026* Great emulsion, first time buying this brand and the pre sensitized kind so was pleasantly surprised.
