HCP alternatives, Hardide-A is
also suitable for internal surfaces
and complex shapes, the company reported.
HCP has been a mainstay of industrial coating in aerospace, heavy equipment, automotive and various other
industries for many years. However, the
hexavalent chrome salts used to produce
HCP pose extreme health and environmental hazards.
The safeguarding EU and U.S. regulations mean chrome plating is incurring
rising costs, extensive regulation and
onerous paperwork. Under EU REACH,
HCP use will be severely restricted and
could be banned. A search has been led
by the aerospace industry to find suitable alternatives.
Hardide-A matches the standard
thickness (50-100 microns) and hardness
(800-1200 Hv) of HCP, simplifying the
transition without need for dimensional
changes or drawing re-design. HCP’s intrinsic performance limitations hinder its
more demanding wear applications and
Hardide-A outperforms it in several key
areas. This includes enhanced protection
against corrosion, wear and chemically
aggressive media, enhanced fatigue life
and a non-porous structure.
A number of other alternatives to HCP
are available including thermal spray, in
particular high-velocity oxy-fuel (HVOF)
and emerging processes such as electro-less nickel composite plating, explosive
bonding, electrodeposited nanocrystal-line cobalt-phosphorus alloys and physical vapor deposition (PVD) coatings. To
date, HVOF and other spray coatings
have been considered the best available
alternative to HCP. However, Hardide-A
provides several advantages over HVOF
such as versatile geometric compatibility,
corrosion and fatigue resistance and facilitated finishing.
Extra Protection Made Easy
from Diamond Vogel
Maintenance personnel at hospitals,
schools, nursing facilities and restaurants
have struggled finding a product that can
hold up to the abuse of repeated abrasion
and frequent cleaning while still being
easy to use and store. While water-based
epoxies offer the performance required
for these facilities, the need to mix com-
ponents prior to using the product,
as well as the inability to store mixed
product due to pot life limitations made
these less than ideal solutions. Diamond
Vogel’s new Eas-E-Poxy Pre-Catalyzed
Waterborne Epoxy offers the perfor-
mance they require in a ready to use for-
mulation offering the perfect solution for
ongoing maintenance.
Eas-E-Poxy’s tough, durable finish
will stand up to repeated washings. It’s
resistance to many common chemicals
and great impact resistance ensures it’ll
continue to look great. Eas-E-Poxy ap-plies and cleans-up like latex paint, so
it’s fast and easy to use, and it’s ready to
use straight out of the can, no need to
mix components together. Since there’s
no pot life, you can use it, then store it
on the shelf for touch-ups later. It’s low
odor and low VOC formulation makes
it perfect for use in occupied areas.
Ease-E-Poxy Pre-Catalyzed Waterborne
Epoxy is available in both eggshell and
semi-gloss sheens and thousands of color possibilities.
Hempel Unveils
Hempaguard Hull Coating
Hempel introduced Hempaguard, a hull
coating for the shipping industry that
offers outstanding resistance to fouling
during idle periods and significant fuel
savings, according to the company, The
new patented technology, ActiGuard,
has been five years in development and
is based on silicone-hydrogel and biocide science.
Hempel’s new Hempaguard has shown
excellent fouling resistance of up to 120
days during idle periods, fuel savings of
six per cent on average and effectiveness
when switching between slow and fast
steaming anywhere in the world. The
unique fouling defense system is available
as two separate products: Hempaguard
X5 and Hempaguard X7. Hempel is
offering a performance satisfaction guarantee contract for vessels complying with
a full Hempaguard X7 specification.
ActiGuard integrates silicone-hydro-
gel and full diffusion control of biocides
in a single coating. Surface retention of
the biocide activates the hydrogel, which
effectively holds fouling organisms at
bay, cutting friction to a minimum while
utilizing a minimum amount of biocide.
It also has the long-term stability and
mechanical properties required of a du-
rable solution.
APV Engineered Coatings
Debuts New High-Performance, Customizable
Coating for Flexible Vinyl
APV Engineered Coatings, a manufacturer and marketer of coatings and
chemical products for over 135 years,
has launched a new product, Vynguard
Weldable PVDF. A customizable, high-performance fluoropolymer coating,
Vynguard Weldable PVDF is specifically
engineered to protect flexible vinyl films
used in outdoor applications. Using a
fluoropolymer chemistry originally developed for metal roofing, and for a cost
of less than $. 10 per square foot of vinyl,
Vynguard Weldable PVDF for flexible vinyl materials is able to block 100 percent
of plasticizer migration, be customized to
suit each customer’s performance criteria,
provide protection against the elements
for well over ten years and sustain the
coated product’s aesthetics.
As a result, products coated with
Vynguard Weldable PVDF have a longer
useful life, lower cost of ownership and
maintain their visual appeal throughout their use. In addition, Vynguard
Weldable PVDF is the only coating of
its type offered in both solvent-based
and water-based formulations. Using the
eco-friendly water-based formulation can
substantially lower a company’s environmental remediation costs. The unique
chemistry of Vynguard Weldable PVDF
allows the customer and APV to collaborate on the product’s formulation to produce a coating tailored to the customer’s
specific needs, helping to create differentiation and a unique selling advantage,
the company reports. Vynguard Weldable
PVDF is engineered to be applied using
gravure, reverse roll or knife-over-roll.
The product is developed and manufactured at APV’s facility in Akron, Ohio,
and is shipped to domestic and international destinations. CW
