The TORO Test: Methacrylates In Action!

Written by Brian Steeves on . Posted in Methacrylates

Toro_thumbOn January 25, 2010, Winnipeg was hit with a blast of Arctic air, along with a LOT of snow, most which seemed to settle on or around our office.  NO PROBLEM!  We have our handy Toro snow blower to help dig us out! This machine’s been with the company so long, it has more seniority than 60% of our staff, so it’s not entirely surprising to find some of the parts on this machine are wearing out.

While in the process of cleaning our tiny parking lot, I noticed the chute (where the snow is ejected from the machine) was wobbling around, and about to fall off.  Upon further inspection, I discovered that the chute is attached to a sort of welded flange.  This flange is welded to the main body of the snow blower, and after years of use a section of the flange had broken off.

My first reaction  was “We need a welder, stat!”  but since I don’t have a welder (yet), and it would take too long  to take it to someone with a welder, I had to find another way.

Peter, our Salesman and resident adhesives expert suggested we glue it back together.  So that’s what we did!  After all, we stand behind our adhesives, right?

So we took a few minutes to discuss the details of our application:  Will this MP55310 bond metal to metal?  Turns out it’s not necessarily bonding “metal” to “metal”, since these are painted parts.  We did NOT remove the paint, so technically this is a ‘paint to paint’ bond.  Stay tuned for an upcoming article on “What Are You REALLY Bonding” for some good information on adhesives.

Anyway, back to the story.   e gathered the materials we needed to make our repair:

  • MP55310 Methacrylate Adhesive from ASI®
  • Manual Dispensing gun
  • Short Mixing Tube
  • C-clamps
  • disposable putty knife
  • plastic gloves
  • disposable shop rags/paper towels for cleanup

We removed the chute from the snow blower to allow easy access to the flange.  We used a wire brush to clean around the flange and particularly the damaged area from any loose debris or dirt.  We then positioned the flange section and began applying the adhesive all around the chute opening, making sure to fill the break completely.

Once the glue was applied, I used a putty knife to smooth out the adhesive on the underside of the flange (and to remove any excess).  After 30 minutes, the adhesive was already beginning to cure.



The very next day, I re-assembled the machine, fired it up, and moved a mountain of snow in –30C temperature.  The glue had been curing for just over 18 hours, and it held fast.

UPDATE!  – March 19, 2011:  The snow is almost gone now but we’ve had two major snowfalls since this article was posted.  I’m proud to say that the repair is holding up beautifully!  No signs of loosening of the bonded parts, no flexing, bending, chipping or peeling.  It’s a sight to behold.  In fact, today we had some visitors come to the office to see for themselves!  Yup, they heard that we’d repaired our snowblower’s discharge chute with glue, and they just had to see it with their own eyes.  They were amazed!

Not All Adhesives Are Created Equal

Adhesives in Wall Climbing

Written by Brian Steeves on . Posted in Adhesives, Methacrylates

I sell adhesives, but I’m amazed at the sheer number of applications that I find.  Just recently, I was searching for a hollow wall anchor for a wall-climbing setup that a group of volunteers is building at Christ the King School.  When I called my trusted source for anchors and fasteners, he recommended an epoxied-in threaded rod method.  Hmm.  It’s easy, very solid, doesn’t require high-tech or costly equipment, and just as important… it’s low cost.

The idea is very simple:  Drill a 5/8” hole that’s 1” deep into the masonry wall (avoid the grouted areas if possible).  Make sure to remove all of the dust from your drilled hole using compressed air for best results.   Fill the hole halfway with epoxy (we’d recommend Adhesive Systems MP 5405NS Maximum Performance 2 part epoxy), insert the threaded rod piece.  In this case, we’re using 2 1/2” lengths of threaded rod, so that they’re flush with the 2×4 we’re attaching to the wall.  Wiggle the threaded rod around in the epoxied hole to make sure that the epoxy fills up the threads, and evenly fills the hole.  You’ll have to work fairly quickly, as this epoxy sets in only 3-5 minutes.  Allow the epoxy to cure for about 30 minutes to ensure that it’s solid (though it only really takes 5-10 minutes).. and attach the panels to the wall.  EASY!

IMG00089-20101122-1124Still not convinced this is a good solution?  We tested it!

We took a cinder block, and drilled a 5/8” x 1” deep hole.  Once the glue had cured for an hour, we subjected it to the most destructive of testing methods.  We hit the exposed threaded rod with a hammer!  Our intent was to see how many hits it would take to break either the bolt, the cinder block or the adhesive.  This was a lot of fun, except that nothing broke!

With at least 10 solid hits to the exposed threaded rod, all we managed to do was destroy the threads, and bend the 1/2” diameter threaded rod. The epoxy held firmly in place.  Awesome stuff!
