# 3M Epoxy Adhesive DP190-Gray & 3M Epoxy Adhesive DP190-Translucent

_Published: 2022-04-22_

Both 3M Epoxy Adhesive DP190-Gray and 3M Epoxy Adhesive DP190-Translucent are a two-part epoxy adhesive that delivers exceptional performance with high shear and peel strength.

They can bond to a wide range of materials, such as metals, ceramics, wood, fiberboard, glass, rubber and many plastics. So, [PCB](https://www.bestpcbs.com/) is no exception. But what are the similarities and differences between them?

**Similarities**

- Provide tough, strong bonds through high shear and peel strength.
- Capable of bonding to a wide variety of different materials.
- Deliver extended work-life, providing additional time for adjustment.
- Exhibit good environmental aging properties, delivering long-term durability.

**Differences**

3M Epoxy Adhesive DP190-Gray has a moderately high modulus. With a 90-minute work-life, it reaches handling strength in approximately 10 hours and full cure in 7 days at room temperature.

Additionally, this epoxy adhesive has medium viscosity and self-leveling with a 1:1 mix ratio by volume. But its flexibility and elongation are moderate.
