Before you purchase organophilic clay bentonite, we hope our 20 years of experience can give you more support. In addition to these professional reminders, the application and price of our organo clay are worthy of your trust.

In this article, we will provide you with some basic information about the characteristics, application and preparation of organo bentonite clay, and then we will use our specific market case to tell you. I hope you can help with your production and procurement after reading it.

Organoclay Properties

A modified kind of bentonite clay that has several uses is called organoclay and organophilic clay . It is most frequently used in solvent-based paints and varnishes, although it is also utilized in cosmetics, drilling fluids, rubber, and grease lubricants. Organoclay is exceptionally effective in removing oil and organic pollutants from wastewater and is especially popular in transparent systems.

In high and middle polar solvent systems, the solvent based organoclay rheological additive CP-85 can be used. This additive is a free-flowing powder that has a pale yellow tint. It is produced by Zhejiang Camp Shinning New Material Co., Ltd. and is frequently used in industrial paints, especially anti-corrosion paints.

Organoclay's rheological characteristics are crucial for numerous applications, including solvent-based coatings. Smectite clays and organic cations react to produce compounds called organoclays. Typically, the cation is a salt of quaternary ammonium.

At room temperature, organoclays have a large gel volume, while at low temperatures, they have a large equivalent circulating density. These two characteristics aid in regulating the rheological characteristics of drilling fluids based on oil.

Organoclay is a superior stabilizing ingredient that also enhances oil-based drilling muds.

For instance, a fresh organoclay-based oil-based drilling mud showed improved stability. Additionally, organophilic clay enhances hydrogen bonding in oil-based muds. Water droplets interacted more frequently due to the enhanced hydrogen bonding, which increased viscosity and stability.

 

Organoclay Applications

There are several advantages of adding organoclay rheological chemicals to paints and coatings. These substances can boost dispersion and viscosity in addition to color and gloss. Additionally, they can be used with other natural or synthetic colors to create more appealing aesthetic effects. These goods can lower costs while enhancing product quality and longevity.

Paints and coatings, adhesives and sealants, ceramics, and cosmetics all use organoclay rheological additives. They increase the rheological characteristics and viscosity of different liquids. Both coatings with high and low viscosities can be made with organoclay.

Ink compositions for a variety of applications frequently use organoclays. They help control the misting and penetration of inks onto porous materials by providing adequate viscosity and yield. To fine-tune rheology, they can also be used in conjunction with gelled varnishes. Additionally, more open structures offered by recent advancements in organoclay-type compounds negate the necessity for milling. This lowers production costs and boosts throughput generally.

A natural substance called organoclay gives systems rheological features. This material is a byproduct of the reaction between an organic cation and a clay of the smectite type. The normal particle size for it is 10 microns or less.

The type of organic system and the required qualities determine how much organoclay rheological agent is used in paints. It is often included in the formulation weight range of 0.2% to 2.0%.

 

Organoclay Preparation

In order to create organoclay, a chemical process is used to change the clay's crystal structure. In this reaction, low weight polar activators replace the quaternary amine. This method is frequently used to prepare organoclays.

Organoclays were made using a variety of basic ingredients. Deep water drilling is better suited to one kind of solvent because it has a longer alcohol chain and is less hazardous than methanol. In the presence of an organic solvent, these clays displayed morphological and rheological characteristics.

When making organoclays, a cationic surfactant is used for ion exchange (typically a quaternary amine).

Examples

A typical organo clay rheological additive with numerous industrial uses is organoclay. It is utilized in grease lubricants, inks, and paint. It is useful in a variety of industries due to its excellent filtration effectiveness. It also works well as a solvent for pigments.

Smectite clays and organic cations react to produce compounds called organoclays. They are most frequently utilized in coatings that involve solvents. For numerous applications, these chemicals have important ramifications. They can be utilized to provide different coating systems the desired flow behavior.

Rheological additives for paint, inks, and varnishes are sometimes utilized with organoclays. They enhance ink penetration onto porous surfaces, reduce misting, and give good viscosity and yield. To further enhance their aesthetic qualities, organoclays can be combined with other organic or inorganic pigments. The fact that organoclay rheological additives improve a coating or paint's weather resistance is another advantage.

Sources

Rheological additives like organoclay are used to improve a fluid's viscosity and flow properties. It is created as a result of interactions between organic chemicals and clay minerals. A versatile ingredient, organoclay is utilized in a variety of applications. It serves as a thickening agent in both organic and inorganic compositions used in oil and gas drilling. This substance encourages thixotropic behavior, which is preferred during the various drilling phases.

Researchers have previously looked for a rheological additive for transparent systems. This additive must deliver shear thinning and sag resistance without compromising clarity. In order to meet this enduring requirement, the identification of organoclay as a rheological addition represents a substantial advancement. Despite the fact that most people associate organoclays with being opaque and dark, their use in transparent systems has many advantages.

Organoclays raise the yield stress and low shear rate viscosity under these circumstances.

An adaptable rheological additive that can be utilized in an aqueous system is organoclay. It is a fantastic option for many applications due to its capacity to impart high viscosity, shear thinning behavior, and sag resistance. An excellent substitute for gelling agents is organoclay, which can quickly acquire the best rheological characteristics.

Organoclay Supplier

At present, among many suppliers and manufacturers in China, Zhejiang Camp New Materials is a leading organoclay | organophilic clay producer, which is worthy of your trust, because it has ISO certification and has more than 20 years of market experience. Now it has obtained REACH. Therefore, it could export in large quantities in Europe.
