In the automotive industry, the quality of primer coats is foundational to the overall finish and durability of a vehicle's paintwork. NINGBO INNO PHARMCHEM CO.,LTD. introduces the 801-D Organic Bentonite Rheological Additive, a premium solution designed to optimize the performance of car primer coats. This article details how this advanced organoclay contributes to superior application and film properties in automotive primers.

Car primer coats serve multiple critical functions: they ensure adhesion between the substrate and subsequent paint layers, provide corrosion protection, and create a smooth surface for the topcoat. Achieving the correct rheology is essential for these functions. The 801-D, functioning as a potent organic bentonite rheological additive for paint, delivers excellent control over viscosity and thixotropy. This ensures that the primer can be applied evenly through spraying, a common method in automotive manufacturing, without excessive dripping or sagging. The controlled flow characteristic is vital for building uniform film thickness, which directly impacts the protective qualities of the primer.

The 801-D is a versatile additive, particularly effective in medium-to-high polar solvent systems, often found in automotive coatings. Its capability for self-activation in these systems simplifies the primer formulation process, reducing the need for additional activators. This benefit is significant for automotive manufacturers who require efficient and consistent production processes. As a self-activated organoclay for coatings, it streamlines manufacturing and contributes to a more predictable outcome, ensuring that each batch of primer meets stringent automotive standards.

Beyond application properties, the 801-D also enhances the stability and durability of car primer coats. Its anti-settling properties ensure that pigments and other solid components remain evenly dispersed, maintaining the primer's consistency and protective capabilities over time. This prevents issues like premature corrosion due to uneven protective film formation. The additive also contributes to improved mechanical properties of the dried primer film, such as enhanced adhesion and cohesion, which are crucial for the longevity of the entire paint system. Its role as a dispersible antiseptic paint additive hints at its contribution to the protective nature of the primer.

The typical dosage for the 801-D is quite efficient, usually ranging from 0.5% to 1.5% of the total formulation. This efficiency means that manufacturers can achieve significant improvements in primer performance without adding substantial bulk or cost to the formulation. Its ability to function effectively, much like a bentonite rheological modifier for printing oil, by controlling flow and preventing settling, demonstrates its broad utility in liquid systems requiring precise rheological management.
