Rhino Glue is an industrial-grade adhesive that is offered to the public in various forms. The company claims Rhino Glue can bond everything. Let’s take a look at this interesting and lesser-known glue and see if it lives up to the hype!
Rhino Glue is a Cyanoacrylate glue, similar to many other superglues, however, it has other unique additives which give it some unique properties.
Cyanoacrylate glues can be brittle and have trouble bonding to certain non-porous materials such as Plastic and Glass, however, Rhino Glue has no such problems as it has been designed over 15 years of testing to be flexible and able to withstand vibration and impacts.
Rhino Glue offers a unique “Pro Kit” option, which includes three containers of Rhino Glue, one in liquid format and one in Gel format (useful for vertical applications), and an additional smaller container with a brush applicator, useful for larger applications.
Pros and cons:
- Larger bottles than most CA glues
- Bonds quickly
- Dries clear
- Works on almost any material
- Resists water and impacts
- Can be used indoors and outdoors
- Comes with brush on applicator
- Includes both Gel and Liquid formulas
- Strong smell while wet
Rhino Glue is a no-nonsense company. They don’t spend millions on flashy advertisements or marketing, they let their products do the talking. Through word of mouth, and customer reviews (Especially on Amazon) they have built up a great reputation as a very strong, very versatile glue.
Available as a liquid, or a gel (or both!)
Gel formulas are all the rage in the adhesives industry of late. Several of the big hitters such as Gorilla and Loctite have CA gel offerings now.
However, Gel is not always the best option, depending on the surface material (and how smooth it is) a liquid CA may be more appropriate.
Thankfully Rhino Glue understands this, and offer both formulas for sale, either individually or together in their pro kit, which also includes a brush applicator.
Rhino Glue bonds in a matter of seconds. There’s a great video produced by the company themselves with a demonstration of the glue so you can see in real-time just how fast it works!
Similar to all CA glues, it bonds solid in a matter of seconds but may take up to 24 hours to fully cure, depending on the porosity of the surface material, how much glue you used, and the temperature and humidity of your working environment.
Resists heat and moisture
Rhino Glue is perfect for outdoor and indoor use.
It’s not waterproof, but it’s water-resistant – meaning you can use it to repair something in the kitchen or bathroom (where there is high humidity) but not to repair something in your fish tank (where there is constant contact with water).
It’s heat resistant, but as with all CA glues, high temperatures may weaken the bond strength.
Flexible & Impact resistant
Although CA glue is very strong, often the bond created is very brittle and doesn’t stand up to vibrations, impacts or shock.
Rhino Glue has overcome this problem. Their unique formula (which took 14 years to formulate) is more flexible than a regular Cyanoacrylate bond, being able to withstand impacts and vibrations.
Rhino Glue is flexible enough to use on fabric and clothing, but if you need something that’s REALLY flexible, (like for using on shoes) consider using a silicone-based adhesive like Amazing Goop.
How to use Rhino Glue
Rhino Glue is just like any other CA glue. You should take care to use it in a well-ventilated area, and you may want to use gloves to protect your skin from getting stuck.
1: Prepare the surface for bonding
Make sure the surfaces you are going to be bonding are clean, dry, and free from any dust, oil, grease, or moisture.
2: Remove the cap and apply a think layer to one or both surfaces
Remove the black cap that comes with the glue, and if desired replace it with your chosen applicator.
If you’re applying the glue to porous materials like wood or paper, you only need to apply it to one surface. For non-porous materials like glass or porcelain, you need to apply the glue to both surfaces to ensure a strong bond.
Apply a thin layer of glue to the applicable surface(s).
Don’t be tempted to use too much, as this will weaken the bond. The thinner the layer, the stronger the final bond will be.
3: Press the two surfaces together and hold for 30 to 60 seconds.
Rhino Glue bonds very quickly. The manufacturer recommends you hold the pieces together for 30 to 60 seconds until the glue is solid.
The exact time will vary depending on your surface material and your working environment.
4: Allow the glue to stand for a few minutes
Rhino Glue forms a strong bond almost instantly, however, the manufacturer recommends that you leave your piece for a few minutes after bonding, to give it a chance to strengthen.
The bond will continue to strengthen for several hours afterward, but it will be strong enough to handle after only a few minutes.
5: Clean and store Rhino Glue correctly for reuse
Tap the glue container on the table to remove any excess glue from inside the cap. Use a wet rag to remove any glue from the outside of the nozzle or the cap, to ensure the cap doesn’t get sealed on by accident.
Rhino Glue must be stored in a cool, dark place away from any moisture or direct sunlight.
The manufacturer advises the glue will last for up to one year if stored correctly.
What Materials does Rhino Glue work on?
The manufacturer of Rhino Glue claims on the packaging that it bonds “Everything”.
This being a CA glue, that is really not correct and it will still struggle to bond to certain types of plastics.
Check out the list below for some ideas on what will work and what won’t, and check out the customer reviews on Amazon to see what other people are using it for.
Rhino Glue sticks to:
- PVC Plastics
- Polystyrene & Styrofoam
- ABS Plastic
Rhino Glue doesn’t stick to:
- HDPE/LDPE Plastic
- PET Plastics
- Polypropylene Plastic / PTFE
What are the ingredients?
Rhino Glue is made from Ethyl Cyanoacrylate (aka CA). This is the same as any other CA glue such as Gorilla Superglue, Original Super Glue, Krazy Glue, etc.
Each manufacturer also have their own unique additives which are trade secrets and not disclosed.
Rhino Glue Drying Time / Cure Time:
Rhino Glue dries in 30-60 seconds, forming a strong bond.
The manufacturer advises leaving the glue for 5 minutes after bonding to ensure a strong bond.
As with any CA glue, the bond will continue to strengthen even after the initial bond appears strong. It may take up to 24 hours for the glue to fully cure, depending on the
Is Rhino Glue food-safe?
Although Rhino Glue is pretty inert once it’s fully cured, all CA glues degrade when exposed to heat so are not food-safe.
Is Rhino Glue Waterproof?
Short answer: Rhino Glue is not waterproof.
Long answer: It’s not technically waterproof, but it IS water-resistant. That means it’s perfect for use in humid areas, fine for use outdoors where it may be exposed to occasional water, but it’s not suitable for repairing corals in your aquarium or fixing a broken tile in your pool where it’s going to be in constant contact with water.
What color does it dry?
Rhino Glue dries clear and colorless.
Rhino Glue Pro Kit – What is it? Should you buy it?
The Rhino Glue Pro Kit contains two versions of Rhino Glue (Gel and Liquid formats) as well as a third, smaller bottle with a brush applicator.
If you need a lot of glue for a big job, or if you’re going to be gluing a lot of different surfaces – sure, it’s worth getting the pro kit.
However, if you’re just looking for glue for one small repair you will save money by buying an individual bottle.
Safety Data Sheet
Here are the safety data sheets for Rhino Glue. There’s a separate sheet for each of the versions.
How to remove Rhino Glue?
Rhino Glue isn’t the easiest to remove, but with the right tools and a little patience, you will be able to remove it.
The quickest way to remove Rhino Glue is to use acetone. Acetone is found in common nailpolish remover. Solvents may damage some finishes, so don’t use them on expensive furniture.
The second way is to use warm soapy water.
This method is not as quick as acetone, but it is kinder for your skin and the recommended method for unsticking your fingers.
Rhino Glue for Convertible Roof Repairs
Rhino Glue seems to have built up quite a reputation in the auto industry, especially for roof repairs. Rhino Glue works great for this because it sticks to glass, fabric, and metal, and it’s waterproof and can cope with the weather.
