In the high-solid anticorrosive coating of large steel structures, ships, bridges, and containers, do you often struggle to balance thick-film application with the persistent problem of sagging? Excessive thixotropy control can result in poor leveling, compromise film appearance, and even become a potential cause of coating defects.  

Now, CoreChem launches its next-generation product: CORECHEM PAMID-D670 Polyamide Wax Powder – a full upgrade of the market-proven D650, engineered specifically to overcome sagging issues in high-solid primers.  

Derived from our successful D650 formula, PAMID-D670 is an advanced polyamide wax powder optimized through molecular structure modification and activation process refinement.

It inherits the excellent properties of D650, including high efficiency, outstanding stability and easy dispersibility, while significantly enhancing its capacity and strength for 3D network structure formation. Tailor-made for high-solid anticorrosive coating systems with stringent requirements for thixotropy and anti-sagging performance, it delivers exceptional anti-settling, thixotropic and anti-sagging efficacy without compromising recoatability.

PAMID-D670 forms a denser, tougher 3D network structure, endowing coatings with a rigid 3D skeletal structure. The thixotropy imparted by PAMID-D670 is pseudoplastic in nature: it maintains high viscosity at rest to prevent sagging, and its viscosity drops rapidly under shear to facilitate smooth application.  

In-house Application Validation

When fully activated, the dry film thickness can reach over 850 μm—a performance that outperforms competitors and even surpasses our well-regarded D650. This capability effectively suspends pigments and fillers, preventing coating sagging and settling on vertical surfaces and corners, ensuring uniform film thickness, and laying a solid foundation for long-term anticorrosion protection.  

Competitor 550μm                                                        D650 625μm                                                       D670 925μm

The coating delivers an excellent application feel, ensuring smooth and easy operation whether by airless spraying or brushing. Its shear-thinning characteristic guarantees superior atomization and penetration, improving construction efficiency, while the film rapidly regains its structural integrity at rest to prevent sagging.  

Say goodbye to the hassle of sagging during thick-film application. PAMID-D670 builds an unbreakable internal skeleton for your heavy-duty anticorrosive primers.
