3M Scotch-Weld DP100NS Translucent - 5 Minute Flexible Non-Sag Fast Set Epoxy

3M Scotch-Weld DP100NS is a fast-setting, two-part epoxy adhesive that combines flexibility with a non-sag formulation. This thixotropic, paste-like consistency prevents the adhesive from running or dripping, making it exceptionally well-suited for vertical applications, filling gaps, and controlling the bond line thickness. Like other epoxies in the DP100 family, it sets quickly and provides a strong, durable bond on a wide variety of materials.

Popular Applications & Uses
- Bonding components on vertical or overhead surfaces where adhesive dripping is a concern.
- Filling gaps or bonding irregularly shaped parts.
- Applications requiring a controlled, thicker bond line.
- General assembly and repairs on a wide range of substrates, especially where clamping is difficult.
- Encapsulating or potting components where a non-flowing compound is needed.

Industries that Commonly Use It
- General Industrial and Manufacturing
- Transportation and Specialty Vehicle
- Construction and Signage
- Electronics Assembly

Special and Unique Features
- Non-sag (NS) formula allows for clean application on vertical surfaces without running or slumping.
- Cures to a flexible bond, providing good peel strength and resistance to shock and vibration.
- Fast 5-minute work life allows for quick handling of assembled parts.
- Cures to a translucent finish.
- The paste consistency is excellent for filling gaps between mismatched parts.

Comparison Note
- The key feature of DP100NS is its non-sag, paste-like consistency. Compared to other 3M epoxies, the standard DP100 is rigid and runny, while DP100 Plus is flexible and runny. DP100NS is both flexible and thick. Alternatives like Loctite E-20NS and Devcon's 5-Minute Epoxy Gel are also non-sag epoxies designed for similar vertical and gap-filling applications. The choice often depends on the required work life and specific performance characteristics.
