New additive Chemistry for Improved Pigment Suspension Control in Non-Aqueous UV Cured High Performance Coatings

With steady growth of radiation Cured systems for high performance industrial coatings, new challenges constantly arise that require innovative solutions. Obtaining desired sag control and pigment suspension often requires sacrificing coating performance for acceptable spray or roll coat viscosity by varying oligomer to monàmer ratios. Additives for the traditional coatings market may not provide acceptable solutions to many UV formulation problems therefore the need to offer new alternatives arise. This paper will provide insight into a new polyester based rheology modifying additive chemistry to help eliminate some common rheological problems and optimize pigmented UV coatings. Coatings formulators will get a full picture regarding a new developmental composition, its base chemistry and incorporation procedures to enhance coating properties and performance.
