3M Scotch-Weld Primer EC-3917 - Structural adhésive - 1 Quart

3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917 is a heat curing structural adhesive primer for Scotch-Weld™ epoxy based film adhesives. EC-3917 primer contains a corrosion inhibitive pigment for added corrosion protection. When used as an aerospace primer, EC-3917 helps create an adhesive bond that resists attack by salt spray, high humidity and common aircraft fluids.

3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917 helps ensure complete wetting of the film adhesive system to bonding surfaces and improves durability of the bonded structure. It helps simplify production scheduling by protecting the cleaned surface until the bonding operations can be completed. With its sprayable consistency, EC-3917 is capable of high transfer efficiency for less overspray waste. When cured it promotes long-term durability for bonded joints. This aerospace primer can be co-cured with epoxy-based adhesive films at 250°F or 350°F to accommodate a variety of requirements and lessen the burden on inventory.

The Primer Advantage:
3M™ Scotch-Weld™ Structural Adhesive Primer EC- 3917 helps protect surfaces against corrosion. Additionally, this primer can help improve production rates by offering high transfer efficiency for less overspray waste and quick flash off for no wait-time between passes. 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917 also offers these benefits:
