High Performance Urethane Additives DMD230 CAS 152637-10-0 With Aliphatic Slow Reaction


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.

PERFORMANCE SPECIFICATION
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 bubble-free.
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.
MAIN APPLICATIONS
Polyaspartic ester coating is another polyurea to the field of development in recent years . It has an aliphatic slow reaction, high weather resistance and high performance.The utility model claims this coating material is called a third generation polyurea. This product is known by the outstanding phsical propety and color-stable,antiseptic property and easy construction especially suitable for decorative topcoats based on the conventional spray polyurea elastomer. Application fields such as Anti-corrosive Coatings for the bridge and outdoor building. Long lasting protect for the concrete and decorative protection for the furniture. It could also be used as component of the paint for the ground of the industrial factory building and sport field. Based on the other good properties include: excellent elasticity, outstanding flexural behavior and distinguished tensile strength, tear strength, surface hardness and weather resistance. So this product is starting being used as protective coating for fan blades and composite coating for helicopters .Or other high-end application fields.
PACKAGING AND STORAGE
50kg, 200kg net weight in plastic drum or packed according to the customer request; XYLink- DMD230 should be stored in cool, ventilated, rainproof, sunproof and fireproof places. Do not mix it with strong acid,strong alkalis and strong oxidant..Keep the product well packaged without affection of damp in a rainproof and sunproof conditions during transport process.
Storage period is 24 months from the production date,in compliance with standards for transportation and storage conditions.
