Method

<span��Urethane system. Polyamides, often mixed with epoxy resins, are ideal curing agents. Best results are obtained with cycloaliphatic diamines (such as Laromin® C 260, Ancamin® XT, TCD-diamine, xylylenediamine, etc.). When mixed with epoxy resins, Desmocap® 11 acts as a reactive toughening agent.

Compatibility                
Generally, Desmocap® 12 has good compatibility with liquid epoxy resins, tougheners and many liquid amines.

Solubility/Dilution              
Generally, Desmocap® 12 has good compatibility with esters, ketones, ethers, aromatics, various tougheners, turpentine and turpentine. However, the storage stability of the prepared solution still needs to be tested. Polyurethane grade solvents should be used (less than 0.05% water) and should not contain reactive groups. Long-term storage of low solid content solutions may cause turbidity and precipitation.
