PAT-ADD DA 1666 by PATCHAM FZC is unsaturated polyamides with acid polymers. It is a liquid pigment wetting and dispersing additive for solvent-borne architectural and industrial paints. It is utilized as a polar activator to provide excellent gelling in organophilic bentonites. Provides excellent anti-sedimentation features and prevention of pigment flocculation. Bentonite pre-gels, prepared with PAT-ADD DA 1666 outperform in ease of handling, demonstrating higher softness and easy dosage of the gel into the paint batch. The optimal amount of PAT-ADD DA 1666 to be used is system related, but generally is between 0.3 and 0.8% PAT-ADD DA 1666, calculated on the total weight of paint formulation. In case of using the product as polar activator for organoclays, as dosage of 30 to 50% based on the weight of organoclay is suggested, as such typically 10% OC gels can be prepared. It is a REACH compliant.
