Why Adding 4360 Before Grinding Can Permanently Solve the Hard Settling Problem in Solvent-Based Coatings?

Why Adding 4360 Before Grinding Can Permanently Solve the Hard Settling Problem in Solvent-Based Coatings?

In the production and storage of solvent-based industrial coatings, the settling of pigments and fillers is a persistent and troublesome issue. Minor settling can often be stirred back into suspension, but once hard, compacted sediment (commonly known as "hard settling" or "concrete blocks") forms at the bottom of the container, it not only leads to material waste but can also affect film performance due to the inability to re-disperse, potentially resulting in customer complaints. How to choose an additive that provides strong anti-settling performance while minimizing its impact on the coating itself? The Anjeka 4360 Polyethylene Wax Paste Anti-Settling Agent might just be the answer you're looking for.

I. The Pain of Hard Settling: The Hidden Cost of Industrial Coating Storage
For common industrial coating systems such as alkyd/amino baking paints, acrylic/amino baking paints, epoxy, and polyurethane, formulations often contain significant amounts of inorganic pigments and fillers. During prolonged storage, these solid particles gradually sink due to gravity and density differences. If the anti-settling system is ineffective, the particles can compact and solidify at the bottom, forming a hard sediment layer. This not only reduces the actual usable amount of paint per can, increasing hidden costs, but more seriously, these hard lumps cannot be re-dispersed by conventional stirring. This leads to rough film surfaces, uneven gloss, and color distortion during application, directly impacting the quality of the final product and customer experience. Therefore, an effective anti-settling agent's value extends far beyond just "preventing settling"; it is key to ensuring consistent product quality and protecting brand reputation.

II. Anjeka 4360: An Anti-Settling Solution Designed for Grinding Systems
Anjeka 4360 is a dispersed polyethylene wax paste anti-settling agent . Its design purpose is to provide stable, long-lasting suspension support for solvent-based coating systems that require a grinding process to disperse pigments and fillers.

Its core advantages lie in precisely addressing three key pain points:

Effective Anti-Settling, Preventing Hard Caking: 4360 can effectively improve the anti-settling performance of pigments, with the key function of preventing the formation of hard, caked sediment at the bottom of the container . This means that upon opening the can, you see a uniform paste, eliminating the need for laborious cleaning of the bottom and ensuring consistent performance from batch to batch.
Minimal Impact, Preserving Original Properties: Many anti-settling agents, while performing their function, can significantly increase system viscosity or affect film properties. The advantage of 4360 is that its impact on coating viscosity is very slight , helping to maintain the original application rheology. Furthermore, it has no significant negative impact on key film properties such as gloss, yellowing resistance, water resistance, and drying speed . This allows formulation engineers to focus on designing the main performance characteristics without having to compromise due to side effects from the anti-settling agent.
Process-Compatible, Easy to Use: 4360 appears as a semi-transparent white to slightly yellow paste, making it convenient to handle . It is specifically designed for high-shear grinding and dispersion equipment and must be added and dispersed together with pigments and fillers before the grinding process . This allows it to establish a robust anti-settling network simultaneously with pigment dispersion, achieving optimal results.

III. Clear Application Scenarios for Precise Use
Anjeka 4360 is not a universal solution, but its applicable areas are very clear, which actually simplifies the selection process:

Applicable Systems: Widely used in industrial coating fields such as alkyd/amino baking paints, acrylic/amino baking paints, epoxy resin coatings, vinyl resin coatings, polyurethane coatings, and various spray paints .
Classic Case Example: In epoxy floor topcoats, which require high decorative appeal and chemical resistance, 4360 is recommended for preventing hard sediment formation. Its minimal impact on gloss also makes it well-suited to meet the high-gloss requirements of topcoats.

IV. Application Essentials: The Secret to Maximizing 4360's Performance
To fully leverage the performance of 4360, correct usage is crucial:

Timing of Addition is Key: It must be added before grinding, allowing it to undergo the high-shear dispersion process together with pigments and fillers . This is a prerequisite for forming an effective anti-settling structure.
Control Dispersion Temperature: It is recommended to control the dispersion operation temperature between 20-40°C to ensure good dispersion and activation of the wax paste.
Dosage Requires Verification: The general recommended addition level is 0.5% to 5.0% of the total formulation . Due to significant variations in resins, pigments, and fillers across different systems, the optimal dosage must be determined through actual formulation testing.

If you are seeking a reliable solution for settling problems in solvent-based industrial coatings like alkyd, epoxy, or polyurethane, and desire an additive that provides strong anti-settling performance while minimizing its impact on viscosity and film properties, then Anjeka 4360 deserves your close attention.
