Thick-coat sagging/Topcoat yellowing? Your formulation may lack this "Molecular Protective Network"!

In matte coatings, 3D printing, inks, and even lipstick formulations, there exists a material that not only prevents pigment settling but also imparts a silky-smooth texture—polyamide wax! This specialty wax, synthesized through the polycondensation of fatty acids and polyamines, has become a "performance multiplier" for both industrial and consumer products, thanks to its unique thixotropic properties and suspension capabilities.

01. Thixotropy/Polyamide wax

The thixotropy of polyamide wax refers to its characteristic of exhibiting viscosity reduction under shear stress and gradual viscosity recovery after shear removal. This property enables polyamide wax to deliver excellent anti-sagging and anti-settling performance in coatings and other fluid systems.

The core "superpower" of polyamide wax stems from the hydrogen bonding in its molecular structure. Formed through polymerization of organic acids and amines, its molecules contain both nonpolar aliphatic hydrocarbon chains and polar amide groups. The oxygen atoms in amide groups and hydrogen atoms in hydrocarbon chains attract each other to form a hydrogen bond network, creating a three-dimensional web-like structure composed of countless "molecular springs" within the liquid.

In coating systems, after being activated by solvent, polyamide wax forms a robust network structure in paint systems,endowing them with excellent thixotropic properties that provide outstanding anti-sagging and anti-settling capabilities.

When coatings are subjected to shear forces (e.g., stirring, brushing), these hydrogen bonds break, causing instantaneous viscosity reduction and improved flowability. When the shear force disappears, the hydrogen bonds reform and viscosity recovers, achieving the remarkable "shear-thinning, standstill-thickening" effect. This characteristic makes polyamide wax an ideal choice for anti-sagging and anti-settling in coating systems.

02. Star product/Polyamide wax

Today, we are pleased to introduce two high-performance polyamide wax micropowder products - LA XW 70 and LA XW 90, specifically designed for different application requirements:

LA XW 70: The "Savior" for High Film-Build Systems

Technical specifications

• Wider Activation Temperature Range (40-75°C) – Adaptable to diverse process requirements.

• Higher Efficiency Than Conventional Polyamide Waxes – Achieves superior performance with lower dosage.

• Ideal for Heavy-Duty Anticorrosion Systems (e.g., epoxy, chlorinated rubber) – Effectively resolves sagging issues in high-film-build applications.

• Compatible with Low-/Zero-Solvent Formulations – Excellent environmental profile.

LA XW 90: The "Aesthetics Champion" for Topcoats

Technical specifications

Core Advantages:

• No yellowing, no impact on gloss, and even enhances coating brightness.

• Excellent high-temperature resistance, preventing particle agglomeration under heat.

• Superior storage stability: No discoloration, no water absorption.

• Compatible with solvent-based & high-solid systems, including UV coatings and adhesives.

3. Core performance/Polyamide Wax

The "18 Skills" of Polyamide Wax

1. Anti-Sagging

In thick-film applications (e.g., anti-corrosion coatings, wood finishes), polyamide wax's hydrogen-bonded network effectively supports the coating film, preventing sagging caused by gravity.

2. Anti-Settling

By encapsulating pigment particles, it prevents sedimentation, ensuring long-term uniformity and stability of coatings.

3. Thickening & Thixotropy

Precisely adjusts system viscosity to balance application fluidity and storage stability.

4. Broad Compatibility

Widely applicable to solvent-based, solvent-free, and high-solid systems including epoxy coatings, inks, and sealants.

Practical Application Guide/Polyamide Wax

Selection Guide

Thick-Coat/Solvent-Free Systems：First Choice is LA XW 70, flexible activation temperature (from 40°C), prevents particle re-coarsening.

High-Gloss/Topcoat Systems: The Essential Choice - LA XW 90. Zero yellowing, 10% Gloss Enhancement

Application Mastery Guide

Activation Acceleration：Incorporate 1-2% isopropanol (IPA) to boost dispersion efficiency in low-temperature conditions.

Critical Notice: LA XW 90 needs to be continuous stirring during cooling phase to prevent gel network collapse.
