XYLink DMD230 Polyurethane Additives , Polyaspartic Esters Equivalent To
Desmophen NH 1220
XYLink- DMD230 is a polyaspartic esters compound which is
synthesized using dialkyl maleates and amine-terminated polyether
as main materials via Michael Addition Reaction. Then a
polyaspartic acid ester compounds is prepared by special
processing. This product is similar to the Desmophen NH 1220(Bayer)
which belongs to the aliphatic aspartic-ester. The reactive
activity is reduced due to the secondary amine in the molecular
structure ,which is affected by the electronic induction and steric
effects of the substituent group. This product has ideal
processability which could be used as one of the components in the
polyurea curing agent or resin component in the polyurea coatings
based on polyaspartic esters. It also could be perfectly used in
the isocyanurate trimer of HDI and other polyisocyanates.both by
machine coated or brush coated..Coating films derived from this
product have great glossiness and physical property..
XYLink- DMD230 features by the outstanding anti-UV property,
excellent damp heat resistance, great salt spray
resistance,chemical resistance and low temperature property.
Additionally the ether bond of the structure makes the
intramolecular rotation more easier, that makes the material has
excellent elasticity and flexibility. It is known as the ideal
monomer in the solventless high-solids of the two-component
polyurethane or polyurea coatings.
Transparent,clorless to light yellow liquid

soluble easily in organic solvents like ethanol acetone and xylene,
slightly soluble in water.
1.Coatings based on this product has a suitable reaction speed and
good operating performance
2.Efficiency of construction is improved by using coatings based on
this product, due to film thickness increases at a time
3. This product belongs to aliphatic polyureas based on
polyaspartic esters. .Coating films are hard, color-stable.
4. It could be coated directly on the surface of metal due to the
curing characteristics of this product XYLink- DMD230 solid content
is 100%. so there is almost no volatile component
existed..Additionally this product could
be used as anti-corrosion coatings or protective coatings on
concrete surface and wooden articles. And for the most part
5. Coatings based on this product have an extraordinary antiseptic
property, chemical resistance. The adhesion with base
material,paint films, shock resistance, water resistance,
weathering resistance have excellent flexibility. The tensile
strength,elongation and Young modulus are higher.
