Photoluminescent ultraviolet curing silkscreen ink

This is a high-quality ultraviolet curing screen ink that our customers may use for their own production of photoluminescent products. This silkscreen ink is used in many of our own products. You may ask for quotes on prices by using our contact form or use our online catalogue.

The UV curing screen ink is designed for printing on PVC, aluminum- and steel plates. Aluminum and steel plates must be coated with a white basecoat (also available from Metal Safe Sign) before application.

For printing, most stencil materials are suitable, but not simplex amber or lacquer type solvent adhesion films. The ink should preferably be printed in lighting having a low ultra-violet content to be completely free from screen stability problems. The area in which the inks are printed should also be protected from direct sunlight. Mesh no. 28 monofilament screens are recommended. A medium squeegee hardness is recommended. The thickness of the cured ink film must be 100 micron. In a modern U.V. drier equipped with two 80 watt/cm per lamp it will cure at 6-7 meters per min.

Before printing, the adhesion to the substrate always has to be tested. The ink will be cured to a glossy finish with exceptional chemical and solvent resistance.

Technical data
Delivery viscosity: 75 ± 5 sec DIN 6 at 23ºC
Specific gravity: 1,90 ± 0,05 g/cm³
Storage time: 6 months at 10-25°C

Containers should be tightly closed immediately after use. The U.V. ink should not be stored in direct sunlight or near warm pipes, and should be kept away from peroxides.

Test results

In the tables below, general test results achieved with the MSS-SA-III GY strontium aluminate pigments are shown. They will give you an impression of our product-quality.

MSS Test-results ISO 15370:2001 Annex A - 25 lux
Illumination for 24 hours. Complete darkness and reading after 10 and 60 minutes. Light-source is 25 lux. Ask competitors for their qualities in accordance with this standard. Please note: Only 25 lux charging light, and not 1000 lux (DIN 67510) like so many other companies' use! MSS makes products for real-life applications - not laboratory tests.

MSS Test results DIN 67510:1992 - 1000 lux
This is the laboratory test that most suppliers of comparable products refers to. MSS samples were held in absolute darkness for at least 24 hours before the samples were exposed to 25 lux for 24 hours. The following measuring results were achieved:

All our products have passed Fire Test Procedure Code - 2 and 5 necessary for wall and bulkhead mounting in escape routes in enclosed areas. When comparing measuring and test results from other suppliers, ALWAYS ask them what their tests are based on! Test results should reflect the actual conditions where the products are to be used, and not optimal laboratory conditions (contact us for more information).

MSS Test results Measurement according to DIN 67510 Part 2 10x10 strip of LLL - 1000 lux

Lowest visible threshold of 0.3 mcd/m2 reached after : 18030 minutes

Example of Ultra Brite quality - one of our older qualities

Our LLL-systems with the "Ultra Brite"-quality are produced with a photoluminescent layer of 300m on 0,68 mm white-enameled aluminum.
The photoluminescent effect is measured by DIN 67510 part 1 to:
170 mcd after 10 minutes and 27,8 mcd after 60 minutes product-quality.

Test results of our LLL compared to IMO 752(18)

Norwegian Radiation Protection Authority

A common misconception of the use of strontium aluminate pigments is that these pigments are radioactive. This is not the case, and Metal Safe Sign shows here the results from tests at the Norwegian Radiation Protection Authority:
