Physical properties of sodium silicate-based substances make them very attractive for commercial/industrial use. Liquids and solids based on sodium silicate and produced by PQ Corporation have a density from 1.6g/cubic cm. to about 1.4 g/cubic cm.
A very big difference between acrylic and oil paint is the drying time. Acrylics dry in a matter of minutes to hours and oils dry in a matter of hours to weeks! This is a huge factor when choosing whether or not to choose oils versus acrylics.
When latex paint is water based, acrylic is chemical based. As the acrylic has chemicals, it is more elastic than latex paint. The acrylic paint contracts and expands better than the latex paint because of this elasticity. The acrylic paint is more durable as it resists flaking, chalking, and peeling.
