Moisture barrier coatings and sealants comprised of mixtures of organic wax and wax soluble polymer dispersed into one or more components of a thermoset polymer which may form a semi-interpenetrating polymer network when the thermoset polymer is subsequently cured on the substrate. The organic wax and wax soluble polymer substantially improve the moisture barrier properties of the thermoset polymer and provides an effective moisture barrier coating that is non-tacky at the cure temperature of the thermoset polymer, without the requirement for a cooling step.

An encapsulated particle includes a core particle and a polyurethane disposed about the core particle. The polyurethane includes the reaction product of an aromatic isocyanate component and a polyol component. The polyol component includes a polyol derived from an aromatic amine-based initiator and an aliphatic polyether polyol. The polyol derived from the aromatic amine-based initiator has a nominal functionality of 4. The aliphatic polyether polyol has a nominal functionality of from 2 to 4. The weight ratio of the polyol derived from the aromatic amine-based initiator and the aliphatic polyether polyol is from about 1:2 to 2:1. A method of forming the encapsulated particle is also provided.
