Product Description

Master Bond X18 is a specially formulated one component system for bonding and priming polyolefinic surfaces. X18 is a low viscosity(<2,500) solvent based system that is easy to apply and process. Most often, it is used as a primer to promote adhesion of polyolefinic substrates to other kinds of materials, such as metals, ceramics, composites and other kinds of plastics. When employed as a primer, X18 is applied in a very thin layer on to the polyolefinic piece and the solvent allowed to evaporate. This will take place typically in 2-4 hours and can be greatly accelerated by adding heat (15-30 minutes at 150-200°F). After the surface is primed in this manner, an epoxy or silicone is prepared and applied to the substrates, and then allowed to cure. When used in this fashion, X18 is, in essence, a bonding promoter, allowing adhesion to this low energy type of plastic (polyolefin) in a process that is relatively simple and straightforward.

X18 can also be used as an adhesive for bonding one polyolefin to another one. When used in this manner, a thin layer of X18 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°F the curing time will be 1-2 hours. When being used as an adhesive, the maximum area of effectiveness for X18 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 X18 as a primer offers many advantages in handling and processing when compared to other methods of treating polyolefinic materials to allow for good adhesion.
