Card：CovestroCoscot.

Model：Desmodur® N 3390

Product description：

Desmodur® N 3390 It's a fat family polycyanate.(Hexamethyl diocyanate tripolymer)，I'll make a promise. 90％ethyl ester acetate/100 No. Solvent sulfur oil.(1:1)Solvent supply。

Product characteristics：

Solubility/Diluent：Desmodur® N 3390 Available esters、Acetone、Solvents such as aromatic hydrocarbons：ethyl acetate、Butyl acetate、Pyrethroid methoxyacetic acid、Acetone、Methaketone、Methamphetamine、cyclohexone.、Toluene、Diphenyl、100#Distillation of solvent quartz oil and its mixtures。Solubility with these solvents is generally good.。But the storage stability of the made solution must be tested.。Polyurethane-type solvents should be used（Less than water content 0.05 %，No hydroxyl or amino active groups）。Fat hydrocarbons are not suitable for solvents.。

Desmodur® N 3390 Shouldn't dilute to solids 40％Below。Solution with a low base content，Long-term storage will be tumultuous and sedimentary.。

Compatibility：Desmodur® N 3390 The following products are generally soluble:。i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i：Desmodur® N 100、 N 75、N 3200、N 3400、N 3600 and Desmodur® Z 4470Faipulose group polyocyanate；Desmodur® L、HL and IL Aromatic aromatics polycyanate；Desmophen® 670 Polyester polyols；Desmophen® A Polypropyl esters。But the solubility of the solution must be tested.。Desmodur® N 3390 and brominated polyols, e.g., Desmophen® 651 or polyether polyol products such as Desmophen® 550 U Insoluble。
