BRUNO BOCK Chemische Fabrik GmbH &
Co. KG specialises in the manufacture of ORGANIC SULFUR CHEMICALS and is
the world's leading producer of Thioglycolic Acid, 3-Mercaptopropionic
Acid, Thiolactic Acid, and their derivatives esters, Polythiols and
salts.
To expand the product portfolio and
to strengthen a position in the North American market BRUNO BOCK
established EVANS CHEMETICS LP in 2005 which operates from its
production site in Waterloo, New York, USA.
In recent years the range of
Polythiols has been expanded to include new applications and customer
service has been improved by expanding the communication between the
application technology laboratory and customers.
THIOCURE� Polythiols are used in
Coatings, Adhesives, Sealants. Some of these products are also used in
the manufacture of high refractive index polymers for high quality
lenses and glasses.
The mercaptocarboxylic acids and
their esters are used in radical polymerisations as Chain Transfer
Agents (CTA) to adjust the molecular weight of polymers.
3-Mercaptopropionic Acid is used as
co-catalyst in the manufacture of Bisphenol A. With a suitable catalyst
the efficiency of the process can be enhanced significantly. Bisphenol A
is a main raw material in the manufacture of Polycarbonate and Epoxy
Resins.
EVANSTAB� Thiodipropionates are
esters of Thiodipropionic Acid and are used as secondary antioxidants in
a number of polymers like polyolefins, ABS, Styrol-Butadien Emulsions,
and certain adhesives.
The anticorrosive properties of
THIOGLYCOLIC ACID is used in water treatment chemicals or in oilfield
chemicals, here in particular Thioglycolic Acid or its salt AMMONIUM
THIOGLYCOLATE in down-hole applications (drilling muds).
Also for cleaners for metal surfaces
THIOGLYCOLIC ACID can be useful as also THIOLACTIC ACID. This includes
"de-rouging" of stainless steel equipment in ultrapure water systems.
For rim cleaning THIOGLYCOLIC ACID
in form of SODIUM THIOGLYCOLATE solution shows excellent dirt/rust
removal properties as also the iron dust is dissolved due to the iron
chelating properties.
