PRODUCT DESCRIPTION
Hotline® Epoxy Traffic Marking Paints are slow
drying, two component, durable traffic marking paints
intended for use as highway and auxiliary marking
(stop bars, crosswalks, legends, etc.) materials. In
special cases these products may also be used as
markings for airports, factories and even parking lots.
When used as a highway striping material these
products will last 3 to 5 times longer than standard
alkyd and waterborne traffic paint systems.
Epoxy Traffic Marking Paints are 100% solid
materials, which easily conform with current and
pending VOC regulations. These products dry to no
pickup in less than 40 minutes when properly applied
at ambient temperatures of 70 deg F or greater.
Longer cure rates will be experienced at lower
temperatures. Epoxy Traffic Marking Paints should
not be applied when air or surface temperatures fall
below 50 deg F.
APPLICATION CONDITIONS
Epoxy Traffic Marking Paints have excellent
adhesion to both concrete and bituminous surfaces.
To ensure a proper bond, complete removal of any
existing marking material is recommended, making
sure to remove all latent dirt and debris prior to
application.
The presence of concrete sealers or effervescence
on new concrete may also interfere with adhesion
and should be removed. Repainting over existing
Epoxy Traffic Marking Paint is allowed providing the
existing material is still tightly adhered to the
substrate.
APPLICATION RATES
The recommended application rate of Slow Cure
Epoxy Traffic Marking Paint is 15 to 20 mils wet film
thickness (approximately 80 to 110 sq.ft./gallon).
APPLICATION
The pigmented Epoxy Components – TM8212 White
and TM8215 Lead-free Yellow are each applied at a
two to one ratio (2:1) with the Converter – TM8214,
using specially designed airless application
equipment that is capable of application pressures of
up to 3000 psi.
For nighttime visibility, glass beads are embedded
into the Epoxy Traffic Marking Paint film during the
application process. The excellent glass bead
adhesion characteristics of Epoxy Traffic Marking
Paints allows for the use of any type of highway
marking glass bead, but generally two glass bead
application systems are recommended:
Long line application equipment is readily available
from several highway striping truck manufacturers.
Special features of this type equipment include:
- 20 to 24 #/gal standard
M248, Type I or II beads
AASHTO
- 2:1 High pressure pumping system
- 12 #/gal large gradation beads
(~14-20 mesh), plus 12 #/gal standard beads
- Closely controlled heating system capable of
application temperatures of up to 160 deg F for each
component.
The double drop system is designed to provide some
degree of wet night visibility. A silane coating on the
beads may also be recommended.
- Paint guns with self-purging mixing
chambers.
(Impingement type mixing guns are also being
developed).
THINNING AND CLEANUP
Thinning of either the Epoxy component or the
Converter is strictly prohibited.
Walk behind application equipment is not yet
commercially available, although modifications can
be made to truck mounted equipment to allow for
non-highway type applications such as legends and
crosswalks.
Un-reacted Converter and/or epoxy may be cleaned
up with solvent, most typical paint solvents (eg.
xylene) may be used for this purpose. Once reacted,
Epoxy Traffic Marking Paints are unaffected by
solvents.
PACKAGING
Standard packaging for the Epoxy Components –
TM8212, TM82145 and the Converter Component –
TM8214 is 55-gallon drums or 250-gallon IBC
containers with a polyethylene liner.
WHEN TO USE
Epoxy Traffic Marking Paints are durable traffic
paints designed for use in high traffic volume areas
where extended service life is desirable. The
relatively high initial installation cost is offset by the
multi-year serviceability, making Epoxy Traffic
Marking Paints one of the most economical traffic
marking materials on the market today. Epoxy Traffic
Marking Paints are also a 100% solids material
making them ideal for applications requiring low VOC
marking materials.
PRECAUTIONS
For industrial use only. SEE MATERIAL SAFETY
DATA SHEETS. READ AND FOLLOW WARNING
LABELS ON PACKAGING.
Painted surfaces can become slippery when wet.
Traffic paints are not intended for use as floor paints.
Do not use on pedestrian walkways or large surfaces
such as ramps, floors, and stairs which could
become slippery when wet.
