- Properties
PAT-ADD DA 1666 is showing strong wetting properties onto a wide variety of pigment and extender surfaces, contributing to best dispersion stability. The formation of a hard sediment, during paint storage, is very much inhibited, using PAT-ADD DA 1666 in the paint formulation. PAT-ADD DA 1666 is also effective as polar activator for organoclay thickeners. The product ensuires proper delamination and activation of the organoclay platelets; additionally PAT-ADD DA 1666 contributes to improved paint stability and anti-settling activity. 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
- Application
Dispersant and anti-settling agent; activator for organoclay. Polymeric polyamide salt, electroneutral.

- Addition and Dosage
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.. PAT-ADD DA 1666 is best premixed with the liquid ingredients of the formulations, prior to pigment/ solids addition. The optimum concentration to be used depends on the individual requirements and conditions and should be determined experimentally.
