| APPLICATION INFORMATION |
| MESH |
355 or higher mesh counts are recommended for opaque colors
where a single (1) lamp system is used. 305 or higher mesh counts
are recommended for opaque colors, where two (2) lamp systems
are used.
Mesh counts should be selected based upon
the end user’s ability to cure the ink deposit.
|
| STENCIL |
Direct or capillary emulsions that are UV compatible, with a
dry micron thicknesses between 7-10µ is recommended. Thicker
stencils can be used based upon the ability to cure the increased
ink deposit.
|
| SQUEEGEE |
Sharp 70-90 durometer polyurethane blade or multi-durometer
blades can be used. For optimal ink lay down, a sharp 80 durometer
blade is recommended.
|
| COVERAGE |
2,800 to 3,000 square feet per gallon based on film deposit
of .40-to .60-mil thickness.
|
THINNER |
Mix well prior to every use. Although the UVB Series
has been supplied in press ready condition for most applications,
this system may be reduced up to 10% with UVO Universal Thinner.
|
| CLEAN
UP |
Use NSW-824 Screen Wash, or other
UV compatible screen washes.
|
PACKAGING |
Available in one (1) gallon and five (5) gallon
containers. Smaller or larger quantities are available upon request.
|
STORAGE/
SHELF LIFE |
Store all inks in a black polyethylene, tightly
closed container at temperatures between 50° - 77° F.
Avoid direct sunlight and indirect white light. Excess ink from
print runs should be stored in separate containers to avoid contamination.
When stored under these conditions, the UVB Series will have a
shelf life of one (1) year from the date of manufacture. Contact
Technical Service for information
regarding the date of manufacture.
|
INK
HANDLING |
Gloves and / or barrier cream is recommended when handling UV
inks. Safety glasses are suggested, particularly for areas where
ink may be splashed. If skin contact occurs, wash affected area
with soap and water (do not use solvent or thinners).
|
 PROCESSING
GUIDELINES |
| CURE &
ADHESION |
A minimum of 125 mJ/cm² and .300 watts per inch is required
for complete cure. Adhesion should be at a minimum of 95% from
curing unit, with full adhesion within one hour of initial cure.
When using coarser screen meshes, cure conditions may need to
be adjusted for the increased ink deposit. If a loss of gloss
and / or adhesion due to insufficient cure is noticed, the use
of 5—10% UVB Series Mixing Clear will increase light penetration
and improve cure.
|
| OUTDOOR
USE |
Extensive QUV accelerated weathering tests have been conducted
on banners printed with the UVB Series. The UVB Series withstood
1,000 hours of exposure in a QUV chamber, with 4 hour cycle times
of UV light and condensation, with minimal color changes and no
shrinkage. Based on prior correlations of accelerated testing
versus real time Florida exposure, 500 hours is equal to approximately
one year, 45° south Florida. The use of premium grade, long-term
vinyl films is recommended for all applications intended to weather
more than two years. Refer to the product warranty
guide for complete warranty specifications.
Accelerated machine weathering are reference standards and
can not precisely reproduce actual outdoor performance.
|
RECOMMENDED
SUBSTRATES |
1 & 2 sided vinyl banner fabrics, pressure
sensitive vinyl, flexible vinyl, print treated polyester materials
used in the decal market.
Full testing by the end user is recommended to determine suitability
of product for a specific substrate and application.
|
| PRE MASKING |
The UVB Series is suitable for pre-masking. The use of a medium
to high tack adhesive is recommended for good adhesion to the
ink film.
|
| METALLICS |
The UVB-8011 Metallic Mixing Clear is supplied to use for mixing
metallic powders and pastes, such as silver and gold. The increased
viscosity of the Metallic Mixing Clear helps to ensure a good
powder suspension. Recommended mixing ratios are: 8% by weight
of Silver, 20% by weight of Gold. |
