3m 77 vs. 90
The main differences between the 3m 77 and 90 are bond strength and the range of materials they can effectively bond. 3M Super 77 is a versatile option for lightweight bonding tasks, while 3M High-Strength 90 is better suited for heavy-duty applications that require a stronger bond and greater resistance to heat and moisture. You can learn more about these differences below.

3M™ Spray Adhesive 77 (Overview & Applications)
3M™ Spray Adhesive 77 is a multi-purpose, solvent-based adhesive that provides a strong, durable bond on various surfaces, including paper, rubber, wood, cork, glass, metal, felt, fabric, flexible plastic, rigid plastic and flexible foam.
This adhesive can be applied using a brush, roller or sprayer and can be cleaned up with mineral spirits.
I love that 3m adhesive 90 is twice as strong as compared to adhesive 77, and it’s a quicker drying time than adhesive 77.
When applied to a surface, 3M spray adhesive should bond within 15 seconds to 30 minutes at room temperature.
3M spray adhesive 90 and 77 are effective when applied to various surfaces and should dry with little trouble in most conditions—though cold temperatures may slow down drying time by as much as several hours.
The drying time of 3M™ 90 Spray Adhesive is 1 to 3 minutes only. And the drying time of 3M™ 77 Spray Adhesive is 15 seconds to 30 minutes.
Overall, both 3M spray adhesives have a similar price point. The 3M Super 77 Adhesive costs around $11 – $23 per can (depends on the can size), and 3M Industrial Adhesives 90 costs around $13 – $34 per can; (depends on the can size), although you may find it cheaper at some retailers.
There are 3M Low VOC 77 Adhesive and 3M Low VOC 90 Adhesive. Low VOC adhesive means adhesives that offer little to no off-gassing.
A single can of each is enough to last most people months and even years, which means these are great options for cost-effective spray adhesives.
All 3M spray adhesives have a shelf life of 15 months, and there is no difference in quality between them. However, they are not interchangeable, so check which adhesive you need before purchasing.
If you’re looking for an adhesive that dries quickly or holds stronger, choose accordingly. Otherwise, it doesn’t matter which product you choose—they both work well for most jobs.
The 3M 90 spray adhesive with a 4.6 stars+ average rating (1160+ reviews) on Amazon has won many fans. Several Amazon customers thought the adhesive was worth the money.

What is the difference between 3M 77 and 3M 90?
The primary difference between 3M 90 and 3M 77 is that 3M 90 is almost twice as strong an adhesive, while both products can be used to adhere to a variety of materials, including rubber, plastic, fabric, and wood.
What is 3M Super 77 used for?
3M Super 77 is a lightweight, fast-drying adhesive ideal for lightweight materials such as paper, rubber, wood, cork, glass, metal and felt.
For smaller projects and crafts where you need an extra-strong bond in a shorter time frame (because let’s face it – who has hours to sit around waiting for glue to dry?), 3M Super 77 is your best bet for projects on fabric and flexible plastic as well.
Can I use 3M 90 on vinyl?
No. You can use 3M 80 on vinyl.
How long does 3M Super 77 last?
3M Super 77’s durability and longevity are mainly due to its consistency and weight and its reputation for being one of if not the best adhesives on earth for industrial-strength jobs.
Users can expect their 3M spray adhesive to last at least 15 months before needing a replacement due to expiration or other factors that can cause it to lose effectiveness.
I hope that you’ve learned a lot about each of these adhesives and their strengths and weaknesses. Ultimately, it all comes down to preference—but if you want an easy way to get started, I recommend 3M 90 over 3M 70. Because, 3M 90 creates much stronger bonds than 3M 77.
While it’s true that there is nothing wrong with choosing a pricier option if you’re dedicated to professional results, you can often find similar quality in less expensive products too!
