When to Use Hydroxypropyl Methylcellulose For Paints？

The advent of paint has changed people&#;s lives. Painters are like artists who made us start living in the world of all colors. People have never stopped researching when it comes to the formulation of paints. In the last few years, HPMC has started to become an important ingredient in paints. Kemox takes you on an in-depth look at the application of HPMC in paints.

What are the types of paints?

There are various types of paints, each with different components and properties. Different types of paint are suitable for different surfaces. Here are some of the common types of paint we see in our lives:

Oil-based paints

Known for their durability, oil-based paints are a common choice. They are suitable for areas with high humidity and smooth surfaces, such as doors and furniture. However, they have a long drying time and usually require the use of solvents for cleanup.

Water-based paints

Water-based paints use water as a solvent and are an environmentally friendly alternative to oil-based paints. They dry faster, have lower levels of volatile organic compounds (VOCs), less odor, and are easier to apply and clean up. Our common latex paint is a type of water-based paint, and water-based paints are commonly used on home walls. The disadvantage of water-based paint is that it is not as durable as oil-based paint.

Enamel Paint

Porcelain paint is very durable and resistant to damage and stains. It has a glossy finish that is difficult to apply and requires mineral spirits for cleanup. It is commonly used for outdoor surfaces, trim and furniture.

Epoxy Paint

Epoxy paint is durable and resistant to chemicals and abrasion. It is commonly used on concrete floors, garages and in industrial settings. The disadvantage of epoxy paint is that it has a strong odor and requires careful mixing and application during construction.

Real Stone Paint

Real Stone Paint was originally designed for use on breathable, moisture and mold-resistant masonry surfaces. It is breathable and abrasion-resistant and is suitable for use on concrete, brick and a variety of stone surfaces.

In addition to this, there are some other types of paints that are not commonly used in life, such as acrylic paint, chalk paint and spray paint.

Application of HPMC in Real Stone Paint

Real stone paint, also known as liquid stone or stone effect paint, is a kind of decorative paint that can produce a surface effect similar to that of natural stone. Real stone paint creates a realistic stone effect by imitating the color of natural stone and can be used both indoors and outdoors. It is not only aesthetically pleasing, but also weather-resistant and durable, and HPMC plays an important role in this by helping to improve the viscosity and stability of the paint, ensuring that the paint adheres well to the surface and produces a long-lasting, realistic effect.

HPMC in oil and waterborne coatings

Kemox&#;s technical engineers have made a new breakthrough in coatings. After our tests, our HPMC can be used in both oil and water-based coatings. Our experimental basis shows that the durability of the paint we formulated with HPMC is more than two years so that the surface of the paint can withstand the test of various factors. Due to the high cost of HEC, our HPMC can replace or even surpass HEC in some fields.

However, automotive coatings have not yet been broken through as far as the use of HPMC in coatings is concerned. Automotive coatings have their own unique formulas, and HPMC is currently not applicable to the field of automotive coatings. It is believed that in the near future, with the continuous modification and upgrading of HPMC, HPMC can be applied to more coating fields.

Hydroxypropyl methylcellulose and hydroxyethyl cellulose

Don&#;t forget HPMC&#;s cousin HEC (hydroxyethyl cellulose). These two substances are often mentioned together in the coatings industry. Both are cellulose ethers used as thickeners and stabilizers in coatings, and they both have their own unique advantages for increasing viscosity and improving the overall performance of the coating.

Currently, we understand that the majority of our coatings customers are still using HEC. HPMC offers better water retention and open time, while HEC excels in its resistance to microbial attack. The differences between them make them suitable for different applications. It&#;s like choosing between mountain biking and road biking &#; both are great, but choose based on the terrain you&#;re tackling.

In short, HPMC is starting to become a versatile player in the coatings world. From enhancing the performance of real stone paints to making a splash in oil- and water-based coatings, HPMC brings new options to the table. When compared to hydroxyethyl cellulose, they each clearly have their place in the paint world.

Hydroxypropyl methylcellulose (HPMC) is widely used in the painting industry due to its beneficial properties that enhance the performance and application of paints. Here are the key reasons for using HPMC in painting:

1. Thickening Agent

HPMC acts as a thickening agent, which improves the viscosity and texture of paints. This results in better control over the paint's flow and consistency, making it easier to apply smoothly on surfaces. The thickening properties also help in achieving the desired film thickness and reduce the likelihood of drips and sags during application.

2. Improved Workability

The addition of HPMC enhances the workability of paints. It helps in achieving a uniform and smooth application, ensuring that the paint spreads evenly on the surface. This is particularly important for achieving a professional finish, especially in decorative paints where aesthetics are crucial.

3. Water Retention

HPMC has excellent water retention properties, which is beneficial in water-based paints. By retaining water, HPMC ensures that the paint remains workable for a longer period, preventing premature drying. This is especially useful in hot or dry conditions where paint can dry too quickly, leading to issues such as poor adhesion and uneven texture.

4. Improved Adhesion

HPMC contributes to better adhesion of the paint to various substrates. This ensures that the paint adheres firmly to the surface, reducing the risk of peeling or flaking over time. Enhanced adhesion is critical for the longevity and durability of the paint job.

5. Stability and Compatibility

HPMC helps in stabilizing the formulation of paints. It prevents the separation of pigments and other components, ensuring a consistent mixture. This stability is crucial for maintaining the quality of the paint during storage and application. Additionally, HPMC is compatible with a wide range of paint formulations, including latex, acrylic, and other water-based systems.

6. Rheology Modification

Rheology refers to the flow characteristics of the paint. HPMC modifies the rheology, making the paint easier to apply with various tools such as brushes, rollers, or sprayers. It ensures that the paint maintains the desired consistency and flow properties, enhancing the overall application process.

7. Film Formation

HPMC contributes to the formation of a uniform and continuous film on the painted surface. This film is crucial for protecting the underlying substrate and providing the desired finish. The film-forming properties of HPMC also enhance the mechanical strength and resistance of the paint, improving its performance in different environmental conditions.

8. Anti-Sagging Properties

HPMC helps in preventing sagging, which is the downward movement of paint on vertical surfaces. By increasing the viscosity and providing thixotropic properties (the ability to become less viscous under shear stress), HPMC ensures that the paint stays in place and does not run or sag, leading to a more professional finish.

9. Enhanced Durability

Paints formulated with HPMC exhibit enhanced durability and resistance to various environmental factors such as humidity, temperature fluctuations, and UV radiation. This results in longer-lasting paint films that maintain their appearance and protective qualities over time.

Conclusion

The inclusion of HPMC in paint formulations offers numerous benefits, including improved viscosity, workability, water retention, adhesion, stability, rheology modification, film formation, anti-sagging properties, and durability. These advantages make HPMC a valuable additive in the painting industry, contributing to the production of high-quality paints that deliver superior performance and aesthetic results.
