ASMACO 4400 utilizes advanced hybrid polymer technology to deliver the dual benefits of a high-modulus sealant and a powerful adhesive. This neutral-cure formulation ensures strong adhesion and long-lasting elasticity, making it suitable for demanding sealing and bonding tasks across construction and industrial applications. The product is engineered to form a tough, elastic rubber joint that accommodates movement while maintaining structural integrity. One of its standout features is its “non-bubbling” application, even in humid conditions, ensuring a smooth and professional finish. Its excellent bonding strength, weather resistance, and compatibility with a wide range of materials make it an ideal solution for interior and exterior use.
