3M™ Scotch-Weld™ Structural Adhesive Primer EW-5000AS is our sprayable, heat curing, epoxy based structural adhesive aerospace primer containing a non-chromated corrosion inhibiting (NCCI) package that provides protection against corrosive environments. We developed this water-borne solution to deliver comparable performance to solvent based products offering more choices in respective processes.
EW-5000 Low VOC structural bonding primer provides comparable performance to traditional solvent-based options
3M™ Scotch-Weld™ Structural Adhesive Primer EW-5000AS meets multiple customer specs in the aerospace industry. It dries evenly in ambient temperatures and can be handled prior to bake cycle, which improves shop handling over competitive solvent-based systems. Let our technical service and support show you how this water-borne primer can make a difference for you.
Promoting Corrosion Control
Our water-borne formula can be used to apply an anticorrosion coating or heat cured to make the coating more durable. EW-5000AS provides a solvent-resistant coating for future adhesive bonding up to 90 days to allow for optimal process flow and scheduling. The stable coating also protects etched and anodized substrates during storage.
The Primer Difference
3M™ Scotch-Weld™ Structural Adhesive Primer EW-5000AS helps protect surfaces against corrosion. Additionally, this primer can help improve production rates by offering high transfer efficiency for less overspray waste. Let our unparalleled technical service and support show you how this surface treatment can make a difference to your primer line. 3M™ Scotch-Weld™ Structural Adhesive Primer EW-5000AS also offers these benefits:
Primed for Take-Off
- Excellent corrosion protection
- Robust mechanical performance
- Impressive hot/wet durability
- Serves 350°F co-cure requirements
- Sprayable, brush or roller application for a variety of process options
In general, 3M Scotch-Weld™ structural adhesive primers
complement the Scotch Weld™ Structural Adhesives portfolio
and can be used to protect prepared substrates to be bonded. They facilitate "wet-out" of the primary adhesive agent to facilitate the bond between substrate and coating extrudate, then cured to enhance chemical resistance. Our adhesive primers help prepare the surfaces for the bonding agents and improve the conditions so that the adhesives are more effective and create stronger, longer lasting bonds.
