Araldite® AY 105-1 with Hardener HY 991 is a two-component, room-temperature curing epoxy adhesive designed for structural bonding applications. It is a medium-viscosity, flowable liquid that provides high strength, excellent resistance to water, humidity, heat (up to 100°C), and chemicals. Once cured, it forms durable joints on a wide range of materials, including metals, ceramics, glass, rigid plastics, and rubber, making it a versatile adhesive for demanding industrial applications.
This adhesive system is ideal for bonding metals, ceramics, glass, rigid plastics, rubber, and composite materials. It is widely used in industrial assembly, repair, and maintenance, especially in electronics, automotive, and general manufacturing where high mechanical strength and environmental durability are required. It performs well under tropical weathering, heat ageing, and chemical exposure, maintaining strong lap shear performance across various substrates.
