One Component, Primer/Adhesive for Polyolefins

Master Bond® X21 is a specially formulated one component system for bonding and priming polyolefinic surfaces. X21 is a very low viscosity(
X21 can also be used as an adhesive for bonding one polyolefin to another one. When used in this manner, a thin layer of X21 is applied to each surface. The surfaces are then mated and the solvent is allowed to evaporate. When cured at room temperature, it will generally set up in 30-45 minutes with full cures in 12-24 hours. If cured at 150 ºF the curing time will be 1-2 hours. When being used as an adhesive, the maximum area of effectiveness for X21 is about 1 square inch. When used as a primer, there is no such limitation in the size of the pieces. The polyolefin family of plastics is used in almost every kind of industry including aerospace, electronic, OEM, medical devices, among so many others. Using X21 as a primer offers many advantages in handling and processing when compared to other methods of treating polyolefinic materials to allow for good adhesion.
