Characterization                                          Hydrophilically  modified  aliphatic  polyisocyanate  based  on isophorone diisocyanate (IPDI).

Bayhydur 401-60 PGDA might be used as co-reactant for aqueous resins and as hardener for chemically resistant and weather-stable coating systems.

Form supplied                                       Approx. 60 % in propylene glycol diacetate



Solubility / thinnability                          Generally speaking, Bayhydur  401-60 PGDA can be diluted with    different

polar to unpolar aliphatic solvents that are common when formulating lacquers. With polar solvents dilution of down to 20 % solid content can be reached. The storage stability of the corresponding dilutions needs to be checked, thoroughly. Especially, when using benzines dilutions need to

be done with due care and skill. The addition of Bayhydur 401-60 PGDA to the benzine-dissolved binder is recommended. Only PU grade solvents (< 0.05 % water) should be used. Also, the solvents have to be free off reactive groups such as hydroxyl or amino groups.



Compatibility                                              Generally speaking, Bayhydur  401-60 PGDA can be mixed with various Desmodur - and Bayhydur - types, e.g. Desmodur N 3300 or N 3600, Bayhydur 3100, XP 2655 or XP 2547. However, the compatibility must be tested in each case. As well, Bayhydur  401-60 PGDA can be dispersed   in

various waterborne binders such as Bayhydrol - types, e.g. Bayhydrol A 2470, A 2646, A 242, A 2845 and U 2755. The overall formulation (solids content, co-solvent content, type of co-solvent) needs to be considered in order to achieve a stable and properly working formulation. In case you need technical support, please, ask your supplier.

Properties / Applications                       Bayhydur 401-60 PGDA can be easily emulsified into the aqueous phase of

a water-borne lacquers or adhesive and is mainly used as co-crosslinker  for

aqueous resins of the Bayhydrol range.

Coating characteristics of aqueous two-component polyurethane coatings can

be improved by addition of Bayhydur 401-60 PGDA to HDI based Bayhydur crosslinkers, such as Bayhydur XP 2655 or Bayhydur XP 2487/1.

Typical blends of Bayhydur 401-PGDA with said HDI-based Bayhydur crosslinkers contain 5-30 % of Bayhydur 401-PGDA on total solids of crosslinkers.


Benefits of Bayhydur 401-PGDA include for example:


Final performance properties, such as

 

        increase of surface hardness


        resistance to chemicals and solvents



Application properties, such as

 

        significantly longer pot-life, even at elevated processing temperatures


        faster drying


        improved robustness, including an increased blister free coating film thickness

Storage                                                    - Storage in original sealed Covestro container.


-  Recommended storage temperature: 0 - 30 °C.


-  Protect from moisture, heat and foreign material.


General information: Hydrophilic isocyanates are very moisture-sensitive and react with water to form carbon dioxide and  insoluble  urea.  Containers must always be kept tightly closed. Contact with water in all forms (moist air, solvents, moist containers) must be avoided, because of generation of carbon dioxide and the dangerous increases of pressure. Storage at higher temperatures will result in increase of color and viscosity.



Storage time                                          Covestro  represents  that,  for  a  period  of  six  months  following  the   day of shipment as stated in the respective transport documents, the product will meet the specifications or values set forth in section "specifications or characteristic data" above, what ever is applicable, provided that the product is stored in full compliance with the storage conditions set forth in and referenced under section "storage" above and is otherwise handled appropriately.

The lapse of the six months period does not necessarily mean that the product no longer meets specifications or the set values. However, prior to using said product, Covestro recommends to test such a product if it still meets the specifications or the set values. Covestro does not make any representation regarding the product after the lapse of the six months period and Covestro shall not be responsible or liable in any way for the product failing to meet specifications or the set values after the lapse of the six months period.

Labeling and statutory requirements     This product data sheet is only valid in conjunction with the latest edition of the

corresponding Safety Data Sheet. Any updating of safety-relevant information

– in accordance with statutory requirements – will only be reflected in the Safety Data Sheet, copies of which will be revised and distributed. Information relating to the current classification and labeling, applications and processing methods and further data relevant to safety can be found in the currently valid Safety Data Sheet.



Further information                               The  product  is  used  mainly  as  a  hardener  in  coating  materials  or

adhesives. The handling of coating materials or adhesives containing reactive polyisocyanates and residual monomeric IPDI requires appropriate protective measures referred to in the safety data sheet. These products may therefore be used only in industrial or trade applications. They are not suitable for use
