  • Bonding Dissimilar CTE Materials
    , thermal shock or mechanical shock. An adhesive property that comes into account when talking about CTE is glass transition temperature (Tg). The CTE values are usually lower when the material is below the Tg and is in the rigid or 'glassy” region. The CTE values are much higher when the material
  • Filled UV Curable Epoxy Provides Low CTE For Electronic Potting and Encapsulating
    Low coefficient of thermal expansion (CTE) epoxies play an important role in the engineering and construction of electronic circuit boards as well as having great adhesive properties for other assembly operations. These epoxies are used for a variety of different applications such as encapsulation
