Defi nition of Polyurea by the
Polyurea Development Association (PDA), 2000
A pure polyurea coating/elastomer is derived from the reaction
product of an isocy-anate component and a resin blend component
such as amine-terminated polymer resins, and/or amine-terminated
chain extenders. The isocyanate can be aromatic or aliphatic in
nature. It can be a monomer, a polymer, or any variant reaction of
isocyanates, a quasi-prepolymer or a prepolymer. The prepolymer, or
a quasi-pre polymer, can be made of an amine-terminated polymer
resin, or a hydroxyl-terminated polymer resin.
The resin blend must be made up of amine-terminated polymer
resins, and/or amine-terminated chain extenders. The
amine-terminated polymer resins will not have any intentional
hydroxyl moieties. Any hydroxyls are the result of incomplete
conversion to the amine-treminated polymer resins. The resin blend
may also contain additives or non-primary components. These
additives may contain hydroxyls, such as pre-dispersed pigments in
a polyol carrier. Normally, the resin blend will not contain a
catalyst.

Your Competent Partner for Polyurea Coatings
BASF develops, produces and markets a broad range of curing
agents, chain extenders and additives for polyurea coatings.
The company, which bene ts from many years of expertise in
this
area, offers a comprehensive portfolio of amine-based curing
agents.
Complete backward integration that includes even raw
materials
ensures great reliability of supply. As market requirements
keep
changing dynamically, we respond by developing speci c new
products for polyurea coatings. Polyurea spray eleastomers
can
be used as protective coating in many elds such as
automotive,
construction, industrial and housing applications.

Polyurea Technology
Polyurea is an elastomer made from two reactive components
A-component
Isocyanate prepolymers (MDI- based for aromatic systems,
HDI- or IPDI-based for aliphatic
systems)
B-component*
Amines (polyetheramines)
Amine chain extenders
Additives (e.g. pigments, defoamers, ame retardants, etc.)
* BASF is the leading supplier of
ingredients for the B-component.

Additives Baxxodur PC 136 Polyetheramines
Baxxodur PC 136 is a new cycloaliphatic
secondary amine used as a chain
ex tender to modify the reactivity of the
polyurea system. It is applied mostly
in conjunction with polyetheramines
and thus an essential part of the curing
system (B-component).
Among the polyetheramines used as
curing agents Polyetheramine D 2000 is by
far the most commonly applied prod uct.
Addition of Polyetheramine D 230 and
D 400 leads to higher reactivity of the
curing system and also to harder lms.
If very high hardness is desired the tri-
functional Polyetheramine T 403 provides
for a stronger crosslinking. With the very
long-chain Polyetheramine T 5000 as part
of the curing system very exible and
elastic lms are obtained.
In addition to high exibility the Polytetra-
hydrofuranamine 1700 leads to reduced
moisture uptake and swelling as well as
to improved abrasion resistance.
Other additives can be part of the curing
system when speci c properties are
requested. Those can be pigments
for colored lms, ame retardants or
processing auxiliaries as defoaming or
de aerating agents that help to avoid
or remove entrapped gas bubbles.
