Core shell particles toughen different coating chemistries, such as epoxies, vinyl esters, and unsaturated polyester resins, by many of the same mechanisms that are observed in the use of reactive liquid polymers: particle cavitation ahead of the crack tip leading to plastic void growth, termination of cracks, relieving of internal stresses during cure, and microcrack prevention.
