Organoclay for solvent-based coatings
Our organoclay for solvent-based coatings provides reliable thixotropy, excellent anti-settling performance and high transparency across a wide range of solventborne resin systems. Manufactured through controlled organic modification and fine milling, the clay forms a stable gel network when activated in esters, ketones, alcohols and aromatic solvent blends.
This network enhances sag resistance, stabilizes pigments and fillers during storage, and delivers predictable viscosity recovery during brush, roller or spray application. Its compatibility with alkyd enamels, polyurethane topcoats, epoxy primers, metallic coatings and high-solids industrial systems makes it a versatile rheology modifier for coatings requiring consistent appearance, strong vertical hold and long-term stability.
Formulators seeking improved rheology in solvent-based coatings quickly recognize the value of our organoclay due to its stable viscosity build and clear gel formation. The material generates interest when users discover how it enhances sag control, prevents pigment settling and enables smoother application in high-solids systems.
As the benefits become clear—reduced defects, improved storage stability, and enhanced appearance—the desire to incorporate it into multiple formulations naturally grows. This leads to confident purchasing decisions as manufacturers request samples, technical datasheets and competitive quotations to refine their solventborne coating systems.
FAQ – Organoclay for solvent-based coatings
Q1. What advantages does organoclay offer in solvent-based coatings?
It provides controlled thixotropy, excellent pigment suspension, strong sag resistance and stable viscosity recovery during application. It also creates clear gel structures ideal for glossy finishes.
Q2. Is it compatible with alkyd, PU and epoxy systems?
Yes. Organoclay works well in long-oil, medium-oil and short-oil alkyd systems, two-component polyurethanes, epoxies and solventborne acrylic coatings.
Q3. Does organoclay require a polar activator?
In most solventborne coatings, the performance is enhanced with a small dosage of polar activator such as methanol, ethanol, propylene carbonate or acetone. Some high-activity grades allow direct addition.
Q4. How does organoclay compare with fumed silica?
Organoclay provides better long-term anti-settling and anti-sag performance, while fumed silica responds faster but may cause haze or poor clarity in high-gloss systems.
Q5. What is the recommended dosage?
Typical usage is 0.2%–1.0% depending on resin polarity, solvent composition and desired rheology.
Q6. Can it improve application performance?
Yes. It provides smooth flow during brushing, rolling and spraying, reducing curtain tears, sag lines and uneven film formation.
