ABSTRACT:
Polysiloxane polyols and curable coating compositions containing such polysiloxane polyols are disclosed. When present as a component in both ambient-cure and thermal-cure coating compositions the polysiloxane polyols provide improved adhesion, pot-life, tack-times, mar resistance, excellent appearance, film hardness and corrosion resistance. A method for preparing such polysiloxane polyols is also disclosed.
