Exceptional Anti - Hydrolysis Performance: Bio SAH 342 is designed with advanced chemistry that provides outstanding resistance against hydrolysis. Its unique formula forms a protective barrier on the surface of materials, inhibiting the ingress of water molecules and blocking the hydrolysis reaction. This ensures that materials maintain their mechanical properties, chemical stability, and physical integrity even in highly humid conditions.

High Compatibility: The liquid solution exhibits excellent compatibility with a wide range of polymers, adhesives, and resins. Whether it's polyurethane, polyester, or other synthetic materials, Bio SAH 342 can be easily incorporated into the production process without affecting the base material's properties. This versatility allows manufacturers to use it across different product lines, reducing the need for multiple specialized additives.

Ease of Application: With its liquid form, Bio SAH 342 offers convenient application methods. It can be easily mixed into liquid - based formulations, sprayed onto surfaces, or added during the manufacturing process. The solution has a low viscosity, ensuring uniform distribution and quick integration into materials, which simplifies the production workflow and reduces processing time.

Stability and Long Shelf Life: Our manufacturing process ensures that Bio SAH 342 has excellent stability. The solution remains effective over an extended period when stored under recommended conditions. It does not degrade or lose its anti - hydrolysis properties easily, providing manufacturers with a reliable additive that they can stock and use as needed.

Environmentally Friendly: Bio SAH 342 is formulated with an eye towards environmental sustainability. It contains no harmful or toxic substances, and its use does not contribute to environmental pollution. This makes it a responsible choice for manufacturers looking to meet growing environmental regulations and consumer demands for greener products.


Application


Adhesive Industry: In the adhesive manufacturing sector, the Premium Bio SAH 342 Liquid Solution is crucial for creating moisture - resistant adhesives. It enhances the adhesive's ability to maintain its bonding strength in humid environments, making it suitable for applications in construction, woodworking, and automotive assembly, where adhesives are often exposed to varying humidity levels.

Polymer Processing: For polymer manufacturers, this solution is used to improve the hydrolysis resistance of polymers such as polyurethanes and polyesters. It helps in the production of durable products like automotive parts, footwear, and furniture components, ensuring they can withstand daily exposure to moisture without deteriorating.

Coating and Paint Industry: In coatings and paints, Bio SAH 342 is added to enhance the moisture resistance of the final film. It protects the coated surface from water - induced damage, such as blistering, peeling, and discoloration, making it ideal for both indoor and outdoor applications, including architectural coatings and industrial finishes.

Textile and Leather Treatments: The solution can be used in textile and leather processing to make the materials more resistant to water damage. It helps in creating water - repellent fabrics and leather products, which are highly valued in the fashion, outdoor gear, and automotive upholstery industries.
