But what about when it comes to 3M Spray Adhesive 90 vs 77 – which one is stronger? Let’s take a look at both of these heavyweights and find out which one packs the most punch!
When To Use The 3M Hi-Strength 90 Spray Adhesive?
3M Hi-Strength 90 Spray Adhesive is ideal for bonding a wide range of materials with long-lasting strength.
It’s the perfect choice for projects requiring high strength and resistance to heat, moisture, or solvents including paper, cardboard, fabric, foam, metal plastic, and much more.
This adhesive works especially well when bonding large surfaces that require extra coverage and greater bond durability.
When To Use The 3M Super 77 Multipurpose Adhesive?
3M Super 77 Multipurpose Spray Adhesive is best used when needing fast results to keep projects moving ahead.
It provides a fast intense tack that offers an immediate hold as well as adequate open time for the proper positioning of parts.
This spray adhesive bonds a wide range of lightweight materials with a permanent bond.
5 Key Differences – 3M 90 Spray Adhesive vs 3M Super 77 Spray Adhesive
1. Tack Strength
The most significant difference between the two is their tack strength, or how quickly each adhesive grabs onto surfaces.
3M 90 Spray Adhesive has a lower initial tack than 3M Super 77, meaning that it needs more time to bond with materials before it can achieve its full bond strength.
Conversely, Super 77 has an aggressive tackiness that offers a strong initial hold with enough open time to position items accurately.
2. Bond & Full Cure Time
The bond time is also considerably different between the two adhesives; while 90 requires up to 24 hours for the full bonding strength, Super 77 offers a much faster 15-second to 30-minute bond time.
This makes Super 77 a great option for quick fixes on projects where speed is of the essence.
3. Versatility & Coverage
Another big difference between these two adhesives lies in their versatility and coverage.
3M Spray Adhesive 90 offers a high coverage rate thanks to its solid content, and this makes it ideal for large-scale or complex projects.
On the other hand, the 3M Super 77 has an aggressive tackiness that offers a quick bond with a low soak-in property. This makes it better suited for smaller projects where you need fast results.
4. Temperature Range
When it comes to temperature range tolerance, 3M 90 Spray Adhesive is more suitable for low temperatures (down to 8°C).
Whereas Super 77 should be avoided in temperatures below 10°C as this could affect its performance and results significantly.
5. VOC Compliance
Both products meet CARB compliance standards; however, only the 3M Super 77 Multipurpose Low VOC <25% version qualifies for LEED credits due to its low VOC level (<25 %).
This makes it preferable in cases where applications must adhere strictly to environmental regulations such as those found in schools, offices, and other public places with specific VOC restrictions.
These restrictions are mandated by local laws or regulations such as California’s Proposition 65 legislation enacted for health protection purposes.
Both 3M Spray Adhesive 90 and 3M Super 77 are excellent multi-purpose adhesives to have in your toolkit for all types of projects.
When it comes to getting the job done quickly and accurately, rely on 3M adhesives – they’re sure to get the job done right!
