Firstly, The 3A molecular sieve has pore sizes of about 3 angstroms, which makes it highly effective at adsorbing small molecules like water, ammonia, and certain alcohols. It is primarily used for drying and purification purposes, especially in applications requiring moisture removal. -
4A Molecular Sieve
Secondly, With a pore size of approximately 4 angstroms, the 4A molecular sieve can adsorb slightly larger molecules, such as oxygen and carbon dioxide. It is widely used in gas separation processes and drying applications where more specific molecular sieving is necessary. -
5A Molecular Sieve
Thirdly, The 5A molecular sieve has a larger pore size of about 5 angstroms, making it suitable for separating larger molecules like hydrocarbons and heavier gases. It is often used in petrochemical industries, gas dehydration, and air separation processes. -
13X Molecular Sieve
With a pore size of about 10 angstroms, the 13X molecular sieve is more versatile and can adsorb even larger molecules compared to the other sieves. This sieve is ideal for bulk separation processes in industries such as natural gas processing and oxygen generation.

CASE – Coating, Adhesives, Sealant, Elastomers
The CASE (Coatings, Adhesives, Sealants, and Elastomers) industry has greatly benefited from the use of molecular sieves like 3A, 4A, 5A, and 13X powders. These sieves play a crucial role in enhancing the performance and durability of various materials.
-
Polyethylene (PE), Polypropylene (PP), and Polyurethane (PU)
Molecular sieves are used to improve the performance of polymers like polyethylene (PE), polypropylene (PP), and polyurethane (PU). By removing trace amounts of moisture, they contribute to enhanced crosslinking properties during the curing process. This leads to the formation of stronger, more durable materials with superior mechanical properties. Additionally, the presence of molecular sieves helps in VOC (Volatile Organic Compound) removal during polymerization, ensuring that the final products meet environmental standards.-
Enhanced Crosslinking Properties
The improved crosslinking properties achieved by molecular sieves result in polymers that exhibit better mechanical strength, resistance to heat, and chemical stability. -
VOC’s Removal
Volatile organic compounds (VOCs) are harmful emissions produced during polymerization and processing. The use of molecular sieves ensures efficient VOC capture, contributing to cleaner, environmentally friendly processes. -
Highly Hydrophobic
Both PE and PP exhibit hydrophobic properties, making them ideal for applications requiring moisture resistance. The molecular sieves help maintain these hydrophobic qualities by reducing moisture content and preventing any undesired water absorption.

Radiation Curing Coatings – Surface Solidification / Thin Coating Treatment
Radiation curing is a widely used method for curing coatings and inks, where the material undergoes rapid solidification upon exposure to UV or electron beam radiation. The incorporation of static molecular sieves in radiation-curing systems improves the overall quality and functionality of the coatings.
-
Surface Solidification
The role of molecular sieves in radiation-curing coatings lies in their ability to control the curing process. By adsorbing moisture and other contaminants, they allow for a faster, more uniform curing, resulting in a smooth and durable surface finish. -
Thin Coating Treatment
Molecular sieves contribute to the effective application of thin coatings by enhancing the crosslinking efficiency. This ensures that even at low coating thicknesses, the cured material maintains strong adhesion and resistance to wear.
Fiber Glass Sizing – Enhanced Crosslinking Properties, Surface Treatment
In the production of fiberglass, the sizing treatment is critical for improving the adhesion between the fibers and the resin matrix. Molecular sieves, such as 3A and 4A, are added to fiberglass sizing formulations to enhance the crosslinking properties and surface treatment of the fibers.
-
Enhanced Crosslinking Properties
Molecular sieves remove moisture from the fiber surface, creating an ideal environment for better crosslinking of the resin during the curing process. This results in stronger, more durable fiberglass products with improved resistance to environmental stress. -
Surface Treatment
The presence of molecular sieves also aids in better surface treatment of fiberglass by ensuring that any impurities or moisture that could interfere with resin adhesion are removed. This leads to enhanced mechanical properties, better bonding, and improved overall performance of the fiberglass.
Composite Coatings in Automobile Applications – Improved Adhesion, Mechanical, Glass Transition Properties, Flexibility and Hardness
Composite coatings in automobile applications are essential for providing a durable finish while improving adhesion and mechanical properties. Molecular sieves play a key role in these coatings by influencing various aspects of their formulation.
-
Improved Adhesion
The addition of molecular sieves in composite coatings enhances the adhesion of the coating to the substrate, whether metal, plastic, or fiberglass. This is crucial for ensuring that the coating remains intact under stress and environmental exposure. -
Mechanical Properties
Molecular sieves help in achieving superior mechanical properties in composite coatings, such as enhanced tensile strength and resistance to abrasion. By ensuring that the coating remains dry and free from moisture, the sieves contribute to the overall durability of the finish. -
Glass Transition Properties
Molecular sieves influence the glass transition temperature (Tg) of composite coatings, a critical parameter that determines the material’s ability to withstand temperature fluctuations without losing its mechanical properties. With the sieves in place, the coatings maintain excellent performance at both high and low temperatures. -
Flexibility and Hardness
Composite coatings with molecular sieves exhibit a balance between flexibility and hardness. This balance is vital for automotive applications, where coatings need to withstand impacts, scratches, and temperature changes without cracking or degrading.
Waterborne Systems – Water-Based Coatings, Improved Adhesion, Mechanical Strength at High Temperature, Glass Transition Properties
Waterborne systems, which use water as the primary solvent in coatings, are gaining popularity due to their environmentally friendly characteristics. The use of molecular sieves in these systems helps optimize the properties of the final product.
-
Improved Adhesion
Waterborne coatings with the inclusion of molecular sieves show improved adhesion to a wide range of substrates, including metals, plastics, and ceramics. This enhances the durability and longevity of coatings applied to surfaces in various industrial applications. -
Mechanical Strength at High Temperature
Molecular sieves play a crucial role in enhancing the mechanical strength of waterborne coatings, especially at high temperatures. By removing excess moisture and ensuring a more controlled curing process, sieves help the coating resist thermal degradation and maintain its structural integrity even under extreme conditions. -
Glass Transition Properties
In waterborne coatings, the glass transition temperature (Tg) is a critical property that influences the flexibility and hardness of the coating. Molecular sieves help to optimize this property by ensuring that the curing process occurs under ideal conditions, providing a coating that performs well across a wide range of temperatures.
