H.B. Fuller's structural bonding adhesives for differential substrates are designed to handle applications to substrates with different thermal expansion coefficient that cause large bondline stresses and strains.
They are resistant to solvents, salt, humidity, acids, and caustics, and provide reliable temperature cycling capability. Due to their unique bonding properties, they will structurally bond a variety of engineering plastics, composites, ceramics, and metals. They are available in a full range of viscosities and cure speeds to meet specific application requirements. H.B. Fuller’s structural adhesives lend themselves well to high-speed production applications. Whether the application is bonding similar or dissimilar parts, design engineers select H.B. Fuller structural adhesives for the optimum in finished product quality, reliability, performance, and cost effectiveness.
