Starbond Flexible Medium-Thick Cyanoacrylate (CA) - Super Glue (Heavy-Medium), KEG-500

Starbond KEG-500 Flexible Heavy Medium CA Glue is a flexible super glue that has impact and shock absorbing properties.  Also used as an outer coat, it’s possible to sand down and polish KEG-500 to a high-gloss finish.  This adhesive is four times stronger than our standard CA glue, and has a higher resistance to heat, humidity, and natural weathering, making it ideal for outdoor repairs, shoe and boot repair, furniture repair and restoration, and archery applications for arrow fletching and inserts.  With bonding times as long as one minute, this is the perfect glue for heavy-duty bonding to form strong repairs! 

Professional Tip: We recommend our Starbond Accelerator to speed up the bonding and drying times, depending on the materials involved and the volume of glue used.

Starbond High Performance Glue, Simply The Best

I have been using Starbond Glue for a while, it has held up with no issues from any of my customers. I make custom chef, fishing and leather crafting knives. Which places a lot of stress on the materials, so you need that great bond. When you order, it is packaged nicely with fast shipping. When you're making that purchase straight from the company you're skipping the middle man.

I picked this up for my split sections that I make for knife handles and it is incredibly awesome. It has a long enough open time to coat the scales evenly and then press your pieces together with minimal mess. It really helps streamline the whole process. Within 15 minutes you can prep the scales for liners. I did a toughness test on it and needless to say it passed my expectations with ebony wood being ripped off with the piece I removed which took 4 razor blades and a hammer to do I might add. It handles heat extremely well while grinding down silver nickel spacers glued to g-10. It has 4X the impact resistance of regular super glue so it’s tough as nails as well. I’ll never use epoxy for splits again

I’m a HUGE Starbond fan. I use it everywhere/everyday in my shop. Great product, great service. Only one suggestion- put your web ordering address on your “we’ve all been here stickers”. I give those away to my friends who have shops. It is SO easy to look at my text tips from you guys and get an idea and order what I need. I allow NO other text alerts from ANY other company or person but Starbond. Usually I keep my Starbond backup supply in my freezer and I find that I am out when I thought I had some going to the freezer; no problem- I just go to my text and find the last Starbond text- click-order-it’s here. If only everything worked this well.
Highest Regards, AB

We use this CA for assembling our products. It is the only adhesive that I’ve tested that sticks permanently and stays slightly flexible when cured. The only downside for us is that they only sell the 16oz as kits, so we end up with extra bottles and tips going in the trash every month since we use a dispensing system.

Best glue ever. Especially for wood inlay!!

Bob G.

Used this new glue to join 2 pieces of a large dinosaur bone (47”, 155 lbs). I was worried about the pressure on the joint with most of the weight being on either end. Seems to have held up very nicely!

Gavin C.

These adhesives now have a permanent spot on my shelf. I'll be replacing all of my other brand adhesives promptly.

Hey Gavin, thank you for choosing Starbond. We are truly happy to hear that you find great value in using our products, and we promise to continue giving you nothing but the very best!

John M.I.

I received a recommendation from Starbond customer support, that this was the recommended product to use to fill a knot in the treated lumber used on my front porch. It performed exceptionally well, sealing the knot, and it looks 100% better than before. Highly recommend this product.
