Golf Club Epoxy
Adhesives are used in many different sports equipment bonding applications. One such application is that of bonding heads onto shafts for golf clubs. It sounds like an easy application and in principle it is – put some adhesive on the tip of the shaft and then insert it into the club head. Quick… let’s get down to the hardware store and get some epoxy! WAIT…. If the adhesive isn’t strong enough and the head flings off it could be an ugly scene… possibly smashing a golf cart window, more likely embedding in someone’s skull!
So what sort of adhesives are used for bonding golf club heads?
Normally a two-part epoxy is used – but not just any old bog-standard product. Epoxies are generally very high strength in shear, tensile or compression but they are normally rigid and tend to be a bit brittle meaning peel and impact resistance is not so good. However, if you opt for a toughened epoxy containing a rubber toughened matrix, the adhesive bond gives ample resistance to any impact, peel or torsional stress on the joint. It is only a very small joint but the stress concentration in that area is huge.
Permabond offers a range of toughened epoxy adhesives which are suitable for bonding golf clubs. They offer excellent adhesion to carbon, graphite, composite, titanium, steel, wood and many other materials. Cure speed and viscosity can be matched as per the user’s preference. Permabond has a long history of supplying two-part epoxies into the golf-bond industry for the manufacture of golf clubs.
Benefits of Permabond 2-part toughened epoxies include:
