Introduction
to Xylan formulations
From
the development of the first Xylan product (1010), Whitford has
modified the basic formulation to solve specific problems. In
this process, we have found new materials and combinations of
materials so that, today, there are more than 1000 different formulations
of Xylan. With proliferation comes the problem of selecting
the best Xylan formulation for your particular application.
Below is a guide to some of the various Xylan products commonly
used, a brief description of each, and how each is employed.
Xylan dry-film lubricants can solve numerous
engineering problems, including friction/wear, corrosion, temperature
extremes, sticking, vibration, galvanic activity, electrical
insulation and conductivity.
Few products are as beneficial in so many ways
as the wide range of Xylan coatings. This very diversity, however,
means that properties can vary widely.
The choice of a coating depends on determining
the problem of the application (wear, heat, corrosion, etc.)
and matching this with the material that most effectively solves
the problem.

Coating
characteristics |
Typical
applications |
| 1000 |
Solvent
and Water |
Premium
dry-film lubricant, with widely varying properties; hard,
heat stable, excellent broadband corrosion barrier; flexible
cure schedule; can be formulated to have good release; electrical
conductivity; fair UV stability. |
Sliding
mechanisms, bearings, large fasteners, power screws, valves,
machine parts, pistons. |
| 1200 |
Water |
Good
friction and release at low cost; good UV stability and
outdoor weathering characteristics. |
Saw
blades, cutting implements, small fasteners, stampings. |
| 1300 |
Water |
Excellent
abrasion and chemical resistance, primarily for ferrous
substrates; must be cured above 375°C/700°F. Hot
hardness not as good as 1000 Series. Good UV stability. |
Pump
components, slurry impellers, valve bodies, molds. |
| 1400 |
Solvent
and Water |
Excellent
chemical resistance, particularly to bases. Good UV stability. |
Large
fasteners, automotive components. |
| 1500 |
Solvent |
Highly
colorful, comes in many colors (primarily decorative, with
good release). Resists household chemicals. Excellent UV
characteristics. |
Decorative
parts for automotive and appliances, plastic valves, personal
care products. |
| 1600 |
Solvent
and Water |
Tough,
with good hot hardness. Provides primary and secondary lubrication. |
Automotive
engine pumps and compressor applications: journal bearings,
wrist pins, piston skirts. |
| 1700 |
Water |
High
release, good toughness, good film build to achieve greater
abrasion resistance and better barrier properties. |
Copy
rollers, immersion heaters, heat-sealing bars, CPI vessels. |
| 1800 |
Solvent
and Water |
Maximum
nonstick (release) properties; perfoms well on parts that
are post-formed. |
Molds
and other components that require best release; sheet metal
parts that are deep drawn or stamped. |
| 2000 |
Solvent
and Water |
Low
friction, abrasion resistant coatings which exhibit high
flexibility.
Wide color & texture range available. |
Rubber
sealing systems, particularly automotive. |
| 5200 |
Solvent
and Water |
Formulated
for dip/spin and other bulk application techniques; outstanding
corrosion protection from salt spray and acid rain. Wide
selection of colors. |
Fasteners
and other small parts that need as much as 1000 hours of
salt fog protection and/or must endure up to at least 30
cycles in Kesternich test. |
