\n Electronic Component<\/span>\n Potting<\/span>\n <\/h1>[\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]Electronic components inherently require protection from moisture and mechanical damage. For this reason, they are typically sealed with materials offering protective properties. Components such as capacitors, switches, and relays are typically designed with shallow cavities for containment, so that low viscosity potting materials may be dispensed quickly during automated production.[\/vc_column_text]\n

Both adhesive brands are specifically formulated to act as barriers against contamination, chemicals, moisture, and handling damage. These materials dispense easily, cure quickly, and provide a protective surface that is dry and tack-free. Hoenle’s broad selection of potting materials bond to a variety of substrates including ABS, nylon, polycarbonate, and plated metals.<\/p>\n

[\/vc_column_text][vc_column_text css=””]Adhesives of the Vitralit\u00ae line are light curable potting materials. They are single component and solvent-free, and are easily dispensed from automated valve dispensing systems. A wide range of viscosities are available to meet component configuration and processing challenges. When cured, these materials exhibit dry, tack-free surfaces that resist contamination from airborne particulates and handling. Light curable materials are available with a secondary moisture or thermal cure catalyst in the event that shadowed areas exist in the potting field.<\/p>\n

[\/vc_column_text][vc_column_text css=””]LED curable adhesives are included in Hoenle’s product selection for electronic component potting and encapsulating. These adhesives fully cure in fractions of a second under low intensity UV or Visible light. They are ideal for use with LED light curing units; depending on the irradiation surface, Hoenle’s floodlights are particularly suitable.<\/p>\n

[\/vc_column_text][vc_column_text css=””]Structalit\u00ae adhesives are solvent free single or two-component adhesives. They are mostly based on epoxy resin and can be cured at room temperature or by exposure of heat. For heat-sensitive components low temperature curing adhesives are available.<\/p>\n

[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”283″ img_size=”full” css=””][vc_column_text css=””]Try our new single component epoxy adhesives that cure at low temperatures (60 C\u00b0). These products are ideally suited for potting temperature sensitive components.[\/vc_column_text][vc_empty_space][vc_column_text css=””]Downloads<\/strong><\/p>\n
