Transparent adhesive

Araldite(R)2026 is formulated to be a resilient, room temperature curing, transparent two-part polyurethane adhesive for transparent substrate bonding, such as polycarbonate, polymethyl methacrylate, 'perspex,' and glass. According to the company, it is water clear and temperature and UV resistant. Intended for applications where invisible joints are required, possible uses include signage, display cases, roofing, lenses, medical equipment, and decorative items.

Adhesive

Intended for hard-to-bond plastics, composites, and dissimilar substrates, this company's toughened structural adhesives are formulated to require minimal surface preparation and cure rapidly at room temperature to high-strength bonds that are resistant to weathering, humidity, and variations in temperature. Plastic Welder(TM)is a two-part methacrylate adhesive that cures in less than one hour with high tensile shear strength of 3,500 psi. It can be used at temperatures up to 250F.

Acoustic material

Soundamp(R)is a family of noise attenuating metal laminate products based on the "constrained layered" vibration damping principal. The acoustic material can be used to replace standard homogenous metal panels or formed parts, which traditionally require additional sound insulation treatments. It consists of two outer sheet metal skins with a thin viscoelastic polymer inner layer.
