Self-matting waterborne polyurethane (WPU), a kind of novel functional coating, is able to avoid the defect of matting agents.
WPU dispersions in which isophorone diisocyanate, poly-1, 4-butylene adipate glycol, 2, 2-bis(hydroxymethyl)propionic acid (DMPA) and trimethylol propane were all used as raw materials of polyurethane prepolymer, triethyl amine and/or N, N-dimethylethanolamine (DMEA) as neutralizers, hydrazine hydrate and 2-[(2-aminoethyl)amino]ethanesulfonic acid sodium salt as post-chain extenders, were synthesized by prepolymer emulsification process.
The matting comparison of a series of WPU dispersions without DMEA and another series of WPU dispersions containing DMEA were discussed to find out the effect of DMEA on the self-matting waterborne polyurethane.
The results indicate that the mean particle size of WPU dispersions is maintained about 2100 nm, the particle size distribution is uniform and the DMPA content has slight effect on the particle size of WPU dispersions when the DMEA mass fraction is 1%.
The series of WPU containing N,N-Dimethylaminoethanol have lower transparency, at the same time, spherical granules pack tightly in the surface morphology via SEM.
It is most worth noting that the surface gloss at 60° of all samples containing DMEA.

These acid-base reactions are exothermic.
The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base.
Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides.
Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
N,N-Dimethylaminoethanol may react vigorously with oxidizing materials.
