Acrylate structural adhesive
Acrylate structural adhesive is a two-component, reactive adhesive formulated from acrylate monomers, elastomers, initiators and other components. It cures rapidly and exhibits strong adhesion to difficult-to-bond surfaces such as oily metals, engineering plastics and composite materials. It offers a structural bonding solution that combines high strength with excellent impact resistance, and is commonly referred to as “acrylic AB adhesive”.
Silicone structural adhesive
Silicone structural adhesives are room-temperature vulcanising or heat-curing elastomeric adhesives composed of hydroxyl-terminated polydimethylsiloxane as the base polymer, combined with cross-linking agents, fillers and other components. Their molecular backbone consists of siloxane bonds (Si-O-Si); upon curing, they form a flexible elastomer that maintains excellent elasticity and sealing performance across the entire temperature range. They are primarily used in structural bonding and sealing applications where stringent requirements for weather resistance, resistance to high and low temperatures, and long-term movement and deformation are essential.
Epoxy structural adhesive
Epoxy structural adhesive is a high-strength engineering adhesive composed of an epoxy resin matrix combined with a curing agent, toughening agents, fillers and other components. It cures through a chemical reaction rather than solvent evaporation, forming a three-dimensional cross-linked network structure upon curing. It provides excellent adhesion to metals, ceramics, glass, timber and most rigid plastics. Whilst withstanding high loads, it also offers properties such as sealing, insulation and temperature resistance, making it one of the key materials used to replace welding and mechanical fastenings in sectors such as aerospace, automotive manufacturing, electronic packaging and structural reinforcement.
Polyurethane structural adhesive
Polyurethane structural adhesives are high-performance adhesives based on polyurethane prepolymers that cure through exposure to moisture or heat to form elastic polymers; once cured, they exhibit outstanding toughness and resistance to impact fatigue. They form strong bonds with a wide range of substrates, including metals, composite materials, engineering plastics, timber and concrete, whilst offering an adjustable modulus of elasticity that can range from semi-rigid to highly elastic. Consequently, it is particularly well-suited to applications requiring vibration damping, impact resistance and tolerance to deformation, and is one of the core adhesives used in sectors such as automotive manufacturing, construction assembly and composite material bonding.
