How can I formulate two-component polyamide-based epoxy coatings to lower solvent content without losing performance or adding cost to my system?

To reduce VOCs of polyamide-based epoxy coatings, formulators typically rely on lower viscosity polyamides, amidoamines, reactive diluents or plasticized polyamide adducts. Each of these routes has disadvantages.

Coatings based on lower viscosity polyamides, amidoamines and/or reactive diluents suffer from slower dry times relative to higher viscosity polyamides. They also have a higher tendency to form amine blush and can be less flexible.

Plasticized polyamide adducts can also suffer from amine blush, although generally to a lesser degree. Plasticizers, such as benzyl alcohol, contribute to VOC levels. This route typically adds cost to the formulated coating.

Novel polyamide products, Ancamide® 801 and Ancamide 802 curing agents, offer a cost-effective alternative to other lower VOC options while maintaining performance.

These robust products are plasticizer-free, 100% reactive polyamides that offer the unique combination of reduced viscosity and high equivalent weight. They allow you to formulate to lower VOC levels without a loss in performance or an increase in cost. In addition, because they are lower viscosity, you can optimize filler loading to reduce system cost while maintaining your VOC compliance and performance.
