| 2U340 is a single-component, fully reactive hot melt adhesive that cross-links through a chemical reaction with moisture found in the surrounding air and substrates, to produce a thermoset adhesive. 2U340 was specifically formulated for difficult to bond plastics, such as ABS and vinyl, to a wide variety of metals. 2U340 was designed to give good balance of properties. The rheology of the product gives excellent release from roll coaters and no stringing of adhesive. The open time of three minutes is adequate for assembly of a wide variety of applications. Green strength development of greater than 50 psi in 15 seconds holds difficult substrates together after combining. Long term aging studies show excellent retention of adhesive properties. Features and Benefits: - High heat resistance (passes B4 boil test), cold resistance, moisture resistance and good chemical resistance
- Very high peel strength
- High green strength
- High strength bonds and great flexibility ideal for differential substrate assemblies
- Good adhesion to a variety of substrates, core stocks and skins including ABS, vinyl, and wide variety of metals
- Longer open time accommodates many industrial assembly applications
- Good low temperature performance
