PA660 soluble / dilution:
Typically, PA660 has a good compatibility with esters, ketones, ethers, aromatic, a variety of toughening, turpentine and Kristallöl ® 60 (turpentine) . But still test the storage
stability of the diluted solution. PU grade solvents should be used (water content less than 0.05%), a solvent should not contain reactive groups. Long-term storage of low
solids content of the solution may appear cloudy and precipitation.
PA660 Compatibility:
Typically, PA660 has a good compatibility with liquid epoxy resin, plasticizer and various liquid amine.
PA660 features / applications:
PA660 can be used to prepare a curable solvent-free liquid polyurethane system. Usually mixed with an epoxy resin curing agent used is preferably a polyamine curing agent.
Best results are obtained with the use of cycloaliphatic diamines (such as Laromin ® C 260, Ancamin ® XT, TCD-diamine, xylene diamine, etc.). When using epoxy resin,
PA660 reactive toughener role.
PA660 Storage:
PA660 epoxy toughening agent should be stored in original sealed containers, sealed after opening to pay attention at all times. Stored at high temperatures may cause an increase
in viscosity.
PA660 safety hazards identified:
According to the standard (Council Directive 67/548/EEC or 1999/45/EC), epoxy toughening agent PA660 does not classified as dangerous.
Should strictly comply with the product safety data sheet. It contains information on labeling, transport and storage, as well as relevant information on handling, product safety and
ecology.
