Studies on the effect of structural parameters on the properties of polysiloxane/urethane dispersions as coatings

摘要

A study on the effect of introducing double bonds and siloxane segments into a polyurethaneurea chain on the properties of the polyurethane and polyurethane-acrylic/styrene dispersions and coatings was carried out.To investigate this effect a 2~3 factorial experiment was designed,with three independent variables [X1-poly(acrylic/styrene) component content;X2-unsaturated diol content in diol mixtures;X3-content of siloxane oligomer diol segments in the diol mixture].
