Polyamide 140A stands as a testament to innovation in the chemical industry, representing a highly versatile reactive polyamide with medium-to-low viscosity. This exceptional compound is engineered to work seamlessly with various epoxy resins, delivering cured products that exhibit outstanding properties crucial for demanding industrial applications.

One of the primary advantages of Polyamide 140A is its ability to impart a remarkable balance of performance characteristics. When combined with appropriate epoxy resins, the resulting paint film boasts a desirable blend of good hardness and flexibility. This dual quality is vital for coatings that need to withstand physical impact while also resisting cracking or brittleness under stress. Beyond mechanical strength, the cured product also demonstrates excellent leveling capabilities, ensuring a smooth and uniform finish, along with enhanced toughness and elasticity. These features contribute significantly to the longevity and protective efficacy of the final application.

A notable feature of Polyamide 140A is its excellent chemical resistance and solvent resistance. This makes it an ideal choice for environments exposed to harsh chemicals, aggressive solvents, or corrosive agents. Such resistance ensures the integrity and durability of coatings, especially in demanding industrial settings. Furthermore, its formulation allows for a wide adjustment range in the mixing proportion, offering formulators considerable flexibility in tailoring properties to specific project requirements. This adaptability is complemented by a long operating time, providing ample working window for application and precise manipulation, a critical factor for large-scale or intricate projects.

The applications of Polyamide 140A are extensive and diverse, spanning numerous sectors where high-performance epoxy systems are essential. It is widely utilized in the formulation of anti-corrosion coatings, offering robust protection for metal surfaces against rust and degradation. In the realm of flooring, it is a key component in epoxy floor paints, contributing to their durability, aesthetic appeal, and resistance to wear and tear. Primer coatings also benefit greatly from its inclusion, providing superior adhesion to substrates and preparing surfaces for subsequent layers. Its excellent adhesion and elasticity make it invaluable in various adhesive and sealant formulations, ensuring strong, lasting bonds and flexible seals. Moreover, Polyamide 140A plays a significant role in electronic component packaging and a multitude of two-component epoxy resin coatings, where its reliable performance and protective qualities are highly valued.

The physical and chemical properties of Polyamide 140A further underscore its quality. It typically appears as a yellowish transparent liquid. Its viscosity ranges from approximately 8000 to 17000 CPS at 40°C (BH model), with an amine value between 360 and 400 mgKOH/g. The color, measured by the Gardener scale, is usually between 8 and 10, and it boasts a 100% solid content (2g/3h/105°C). The Amine Hydrogen Equivalent Weight (A.H.E.W) is consistently within the 100-120 range. These precise specifications ensure consistent quality and predictable performance.

For industries and businesses seeking high-quality chemical solutions, understanding the availability and procurement process for such materials is crucial. If you are looking for a reliable polyamide 140A manufacturer or a reputable epoxy hardener supplier, it is important to consider providers with a strong track record in manufacturing and exporting new epoxy materials. Competitive polyamide 140A price and streamlined processes for you to buy or purchase the product are key factors. Collaborating with experienced suppliers who offer strong R&D capabilities and customized services can ensure you receive products tailored to your specific needs, facilitating sample testing to validate performance before large-scale commitments.
