Surface Performance Characteristics
| Characteristic |
P3
ceramicsteel Markerboard |
| Writability |
Can be written on with any dry-erase,
semi-permanent, water-soluble, permanent marker, pen, or crayon
without damaging the surface. |
| Visibility |
Contrast/waviness for markerboards
(light and dark effects) shall be no greater than 15 when tested
with BYK-Gardner Wave Scan 5+ Measurement device showing visual
acuity (contrast sensitivity) to the human eye at distances
greater than 3 meters (10’–0”). Resolution
(visual acuity) shall be based on 3 lines per degree and be
visibly maintained beyond the current standard of 3 meters. |
| Erasing |
Dry-erase marker ink can be wiped
off easily with a dry cloth or standard eraser. Crayon, semi-permanent,
and permanent marker pen inks can be removed with a solvent
based or light abrasive cleaner. |
Cleanability
(Washability) |
All residues that remain after normal
erasing can be removed by following the care and cleaning instructions
on the www.CleanMyBoard.com
website. |
| Wearability |
Vitrified glass-hard ceramic surface
fused to light-gauge enameling grade steel at approximately
800° C. High resistance to impact damage, abrasion, scratching,
and color fading. The PolyVision surface registers a 6.5 on
the revised Mohs hardness scale. |
| Magnet Capability |
The P3 ceramicsteel
surfaces are ideal for all magnets and magnetic impregnated
materials and will not be scratched or damaged from the contact. |
| Flame Resistant |
The P3 ceramicsteel
surface is 100% non-combustible. |
Materials
All ceramicsteel panels will be supplied with PolyVision light
gauge steel face. The ceramic finish is fused to the steel sheet
at a temperature of approximately 700°
C. for chalkboard and 800° C. for
markerboard.
Finishes
The ceramic finish will consist of a specially formulated
glass substance applied by machine. Base metal will be coiled enameling
steel of an alloy suitable for the application of architectural
porcelain, employing a continuous coil process. Base metal will
be properly pre-cleaned and treated, to ensure complete bond between
the steel and the subsequent ceramic coatings. Both surfaces of
steel-based metal will receive a ground coat of ceramic frit to
be fused to the metal in a firing operation used exclusively for
ground coat application to prevent contamination. A color cover
coat of ceramic frit will be applied to one surface of the ground
coat and fused by a firing operation exclusively designed for color
applications. All ceramic coating will be machine applied with automated
equipment for maximum finish uniformity. Firing temperature will
range from 700° C. to 800°
C. The gloss of writing surfaces will not increase by more than
three units when subjected to wearability tests specified in testing.
