What do you seal prismatic reflective vinyl with?

Hi Ian

Depending on what you are doing with the product there are a number of options for edge sealing

Prismatic can be sealed ultrasonically or with a liquid seal, High Intensity is more problematic and would probably only work with a liquid edge seal. If you are supplying for vehicles High Intensity really isn’t suitable as it is too brittle and does not have the reflectivity of a Prismatic product – We only recommend Prismatic on vehicles.

For practicality we edge seal Prismatic Roll Goods/Tape ultrasonically in an inline process where the product is cut and edge sealed in one process. For shapes such as battenburg designs for emergency vehicles they can be edge sealed and cut at the same time using an ultrasonic head attached to a flatbed (we have one attached to our Zund flatbed) We also have a manual ultrasonic sealing tool for smaller runs.

3M make a liquid edge sealer that you paint on which is fine for smaller runs but can be quite time consuming.
Also I read on another post to use the "Seal It" pens for edge sealing …… don’t bother as it doesn’t work we have tried it ourselves and it does not give a thick enough seal to stop edge break down.

Hope this helps

Thanks guys, that’s a real help in my endevours, much appreciated.

An associated question is…..

I have a few ‘patient transfer minibuses to do, they have bright yellow base and red reflective on the rear and along the sides stripes of reflective green and what seems like a fluorescant yellow come green vinyl (cant easy teell what colour because it’s faded badly. Is there a standard manufacturer and colour of this fluorescant yellowy green vinyl or am I safe in just trying to find this colour from Avery, Mactac, 3m or whoever?…

Hi Ian

Patient Transfer vehicles usually follow standard NHS specification which is Prismatic (sometimes specified as 3M Diamond grade or similar) – Colours are Fluorescent Yellow Green and Interstate Green to sides and either Red and Yellow Chevrons to rear or sometimes Fluorescent Yellow Green and Fluorescent Orange chevrons to rear – All colours reflective including the fluorescent colours and all edges must/should be edge sealed. Be careful with the Green as most manufacturers have 2 greens in reflective , one for Traffic Signs (Worboys Green) and one for Emergency services (Interstate Green)

If the sides are just striping then both colours are available in 3M Diamond Grade in standard widths 25mm, 50mm, 100mm, 150mm etc already edge sealed sold as full rolls or by the metre – Same for the rear although some people use roll goods and cut to shape around shapes/windows/door handles etc and edge seal with 3M 3950 edge sealer, others will use pre-cut shapes off a flatbed which can be ultrasonically edge sealed.
