- Description
- Technical specification
For challenging, heavy-duty industry applications, e.g. lightning strike connections to provide additional electrical protection on helicopters, choose LOCTITE® ABLESTIK 57C. This electrically and thermally conductive epoxy-based adhesive is easy to use and highly thixotropic to allow manual application via spatula even in overhead applications. It has an operating temperature of -60°C to 120°C (-76°F to 248°F) and has a medium shear strength.

How to use
Complete cleaning of the substrates should be performed to remove contamination such as oxide layers, dust, moisture, salt and oils which can cause poor adhesion or corrosion in a bonded part.
During shipping and storage, separation of components within the packaging container can occur. For this reason, it is recommended that the products be thoroughly mixed prior to use.
Accurately weigh resin and hardener into a clean container in the recommended ratio (review TDS). Use scale for accuracy.
Blend components by hand, using a kneading motion, for 2 to 3 minutes. Scrape the bottom and sides of the mixing container frequently to produce a uniform mixture.
Apply adhesive to all surfaces to be bonded and join together. In most applications only contact pressure is required.
FAQ
Electrically conductive adhesives (ECAs) deliver more secure electrical interconnection and more reliability versus traditional soldering, especially in challenging application environments (e.g. varying temperatures or dissimilar materials). They are metal filled adhesives with the ability to conduct electric current, typically consisting of a polymeric resin, a hardener and a conductive filler.
Thixotropy comes from the two Greek words thixis (shaking or mixing) and trepo (turning or changing). It refers to the viscosity being temporarily reduced when a stress is applied, e.g. product being extruded/stirred. Thixotropic adhesives allow for managing the flow during and after application. Meaning they are easy to extrude but stay in place after application as they revert back to their initial, thicker state.
