Product Description
PERMABOND® 748 is a flexible cyanoacrylate adhesive, exhibiting improved peel strengths when compared to other grades. It has excellent impact and vibration resistance, and is suitable for bonding dissimilar materials which could be subject to thermal shock or thermal cycling.
748 is ideal for use on flexible or semi porous surfaces. It can also be used to bond silicone when used in conjunction with Permabond Polyolefin Primer (POP).
Features of PERMABOND® 748
- Thixotropic gel
- Flexible, soft material
- High elongation
- Easy to apply and dispense
- Contains no solvent
Application of PERMABOND® 748
- Bonding dissimilar materials which could be subject to thermal shock or thermal cycling
