Troubled by sagging/settling from high powder content in coatings? PAMID D650 high-performance polyamide wax thixotropic agent solves it! Ideal for epoxy heavy-duty coatings—upgrade performance now!
Application Highlights
In coating formulations, the powder content is usually substantial, leading to common issues such as sagging and settling. Settling occurs when powders separate from the liquid phase, and in severe cases, it can lead to hard sedimentation. Sagging happens when the coating applied on vertical surfaces begins to flow due to gravity, resulting in streaks or, in worse cases, drips.
How can these issues be resolved? The perfect solution lies in the use of thixotropic agents. Commonly used thixotropic agents include fumed silica, organic bentonite, hydrogenated castor oil, and polyamide wax. Today, we present a top-performing polyamide thixotropic agent—PAMID D650.
PAMID D650 — Polyamide Wax Thixotropic Agent
Structure and Mechanism of Action
Polyamide waxes contain abundant hydroxyl and amide groups, both of which have extremely strong hydrogen bonding capabilities:
Polyamide wax gradually unfolds at high temperatures, forming a spiderweb-like structure, exhibiting extremely strong thixotropic properties:
Performance Comparison
- Compared to conventional phenolic resin, D650 enhances saltwater resistance by 3 times (competitors usually ≤72 hours).
- Compared to epoxy ester systems, D650 extends wet-film open time to 20 minutes (competitors around 8-12 minutes), making it ideal for large-area applications.
Application in Epoxy-based Heavy-duty Coatings
Performance Display
