Creating new innovations in high-strength bonding

  • Traditional one-part epoxies are rigid adhesives, often requiring a high-temperature thermal cure which results in outstanding strength at elevated temperatures. They are the most environmentally durable adhesives, standing up to extremes of heat, cold, humidity, many solvents and other conditions.

    Innovations in one-part epoxy adhesives are creating more diverse portfolios, with formulations that cure at lower temperatures for greater flexibility and impact resistance. These innovative chemistries are also more conducive to bonding engineered plastics, leading to applications spanning from consumer electronics to military and aerospace.

    Two-part epoxy adhesives have similar environmental resistance but involve two components which cure upon mixing rather than thermally.


  • Discover the Important Attributes of One-Part Epoxy Adhesives


  • Strength

    Epoxies have the greatest strength and durability of all structural adhesives

    Bonding

    Structural adhesives bond dissimilar materials and also provide insulation to resist corrosion when bonding two different metals

    Process Efficiency

    Different chemistries provide a variety of surface preparation, open time and strength-build times so you can find the best options for your process

    Impact Resistance

    Epoxy bonds have exceptional resistance to shock, vibration and impact loads

    Lightweighting

    Adhering to new materials and distributing stress along the entire bond area helps designers use thinner and lighter materials

    NVH

    Vibration resistance reduces opportunities for unwanted noise

    Aesthetics

    Structural adhesives provide better product appearance through invisible joints and smooth bond lines

    Water Intrusion

    Structural adhesives provide a continuous bond line to prevent the migration of fluids, dust and dirt

    Innovation in Design

    The ability of structural adhesives to bond a wide variety of substrates allows the freedom to design for the best materials available
