Automotive and Marine Putty
In the past there were two types of repair putties: lightweight putty that was easy to work but created a bumpy surface, or conventional putty that produced a smoother surface, but was difficult to sand.
The addition Hollow Glass Spheres(Glass microsphere）, alone or in combination with other mineral fillers, effectively increases the volume of the mixture while decreasing the weight and cost per unit volume. The reduced density of putties formulated with Hollow Glass Spheres(Glass Microsphere) allows application to vertical surfaces without sagging or slumping.
Low density putties formulated with Hollow Glass Spheres(Glass microsphere） show improved shrinkage and sand ability.
Higher loading of spherical particles can enable formulators to reduce resin demand without increasing viscosity.

Putties made with TA-10 micro particle sized Hollow Glass Spheres(Glass microsphere） maintain the smooth surface characteristics of conventional resin/talc formulations. At the same time the putties offer the advantages of lowered costs overall and enhanced ease of handling that characterize the lightweight putties.
Adhesives
FEEFK Industries supplies a line of tightly sized solid glass spheres for use in adhesives as a bond line spacer. The spheres, which have a soda-lime (A) composition and a density of 2.5g/cc., are certified to Hughes standard specifications. In general, 90% of the product fits within the gradation specified.
With a crush strength of 30,000 psi, FEEFK glass spheres are incompressible. They are added in small amounts to adhesives and resins to define the bond line thickness.

Plastics
FEEFK Industries supplies two types of glass spheres for use as extenders and performance modifiers in plastics applications
Our spherical particles are strong enough to survive injection molding. They provide improved flow and handling properties in a variety of applications. Unlike irregularly shaped fillers, spherical particles do not adversely affect the viscosity of resin systems.
Because of their composition, FEEFK glass beads exhibit low oil absorption, which makes our products very cost effective. The glass beads also resist stains and thermal degradation.
The physical properties of finished parts can be further improved by using FEEFK glass spheres coated with functional silanes. The coating results in better adhesion between sphere and resin

Highway Safety Marking Spheres
Cost-effective Highway Delineation
Retroreflective pavement markings deliver continuous
roadway guidance to drivers and have been proven to
increase highway safety.
FEEFK Standard Highway Marking Spheres provide
cost-effective nighttime roadway delineation, and meet or
exceed every standard in effect in the United States today.
FEEFK Standard spheres are highly durable and consistent
in quality and composition. Strict quality control produces
truly round spheres that optimize retroreflectivity. Proprietary
coatings are available to resist agglomeration, ensure
flotation for ideal embedment and improve adhesion for
greater durability.
Standard spheres may be applied as a drop-on in all
commercial binder materials, including waterborne paint,
epoxy, polyester, thermoplastic, PMMA and polyurea.
Application Guidelines
To ensure optimum retroreflective performance and
durability, the bead/binder system needs to be applied
in the proper manner:
• Apply the spheres immediately following the
binder application.
• Apply the spheres evenly over the width and length
of the marking.
• Embed the spheres to a level of 60%.
• Apply Standard Highway Safety Marking Spheres
at the rate of:
6–8 pounds per gallon of latex.
20–24 pounds per gallon of epoxy.
10–12 pounds per 100 square feet
of thermoplastic.
FEEFK safety marking sphere dispenser is
designed for optimal application of all types of safety
marking spheres.
FEEFK Standard Spheres: Facts and Figures
Size: 20–80 mesh (850–150 microns); a range of sizes offsets
the effects of traffic and binder degradation.
Compatible binders: waterborne or solvent-based paint,
epoxy, polyester, thermoplastic, PMMA and polyurea.
Typical Standard Bead Size
织梦好，好织梦
Proper application of highway lane markings is critical to good performance of pavement marking systems.
The FEEFK Highway Safety Marking Sphere Dispenser is a gravity-drop glass sphere dispenser with a unique design that adjusts for an even distribution of all sizes of glass spheres. The FEEFK operates on either a gravity-feed or pressure-feed system, and mounts on a striping machine directly behind the marking applicator gun.
• Works with all bead sizes
FEEFK has greater and more accurate bead
throughput for both standard and larger beadloading
applications.
• Easy bead flow adjustment
Readily accessible volume control allows for accurate
and easy calibration of bead flow.
• Universal mounting bracket
A movable mounting block that accepts 1/2” round
stock makes it easy to retrofit any striping vehicle.
• Oversized bead inlet tube
FEEFK can be used on both gravity or pressurized
systems.
• Large-volume storage chamber with tapped opening
A supplied air muffler reduces air pockets and pulsation
on a pressurized system, or an air fitting adds air pressure
to increase bead flow on a gravity system.
• Heavy-duty rubber shroud
A rubber shroud controls bead dispersion, allowing
placement within one inch of the pavement, which
virtually eliminates bead loss due to over-spray or wind.
• Optional shrouds of 5″, 6″and 8″diameter
A 4″shroud, standard with every FEEFK, is easily
interchanged with other available sizes for different
line widths.
• Optional air valve conversion kit
A two-way air cylinder makes the FEEFK doubleacting
with existing single-acting solenoids.
• Protective Cover
A removable shield prevents the accumulation of overspray,
dust and road grime on the adjustment
mechanism.
FEEFK is designed for optimal application
of any type of highway safety marking sphere, on any
field site.
