Cường lực cao trong điều kiện nhiệt độ khắc nghiệt

  • Epoxy một thành phần truyền thống (one component epoxy adhesive) là loại keo cứng, thường phải đóng rắn ở nhiệt độ cao, nên có độ bền chắc vượt trội ở nhiệt độ cao. Chúng là loại keo bền nhất với môi trường, chịu được nhiệt độ cực cao, cái lạnh, độ ẩm, nhiều loại dung môi và các điều kiện khác.

    Những đổi mới trong keo epoxy một thành phần đang tạo ra nhiều dòng sản phẩm đa dạng hơn, với các công thức đóng rắn ở nhiệt độ thấp hơn cho tính linh hoạt và khả năng chống va đập cao hơn. Những hóa chất mới này cũng giúp thuận lợi hơn trong việc Dán các loại nhựa kỹ thuật, dẫn đến các ứng dụng trải dài từ điện tử tiêu dùng đến quân sự và hàng không vũ trụ.

    Keo epoxy hai thành phần có tính kháng môi trường tương tự nhưng bao gồm hai thành phần đóng rắn khi trộn chứ không phải bằng nhiệt.

  • Discover the Important Attributes of One-Part Epoxy Adhesives

    Hotspot selector of Epoxy attributes


Epoxies have the greatest strength and durability of all structural adhesives


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


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


Vibration resistance reduces opportunities for unwanted noise


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

  • 3M™ Scotch-Weld™ Epoxy Adhesive 2214
  • 3M offers both traditional high-heat one-part epoxies and newer formulations that cure at relatively lower temperatures. Explore more options to find the best one for your product and process.
