Here are some tips and tricks for using 3M Super 77 Multipurpose Permanent Spray Adhesive:

• Shake the can well before use. This will ensure that the adhesive is evenly mixed.
• Apply the adhesive in a well-ventilated area. The fumes can be strong, so it’s best to work in a place where you can get some fresh air.
• Hold the can about 6 to 8 inches away from the surface and spray in a smooth, even motion. Don’t overspray, as this can make the adhesive difficult to control.
• Allow the adhesive to dry for a few minutes before attaching the two surfaces. This will give the adhesive time to set and form a strong bond.
• If you need to reposition the two surfaces after they’ve been sprayed, you can do so within 30 minutes. After that, the adhesive will be set and will not be able to be repositioned.
• To clean up any excess adhesive, use a damp cloth. Be sure to wipe up the adhesive immediately, as it can become difficult to remove once it dries.

Here are some additional tips:

• 3M Super 77 is a permanent adhesive, so be sure to use it on materials that you want to bond permanently.
• This adhesive is not recommended for use on porous materials, such as wood or fabric. It will soak into these materials and may not create a strong bond.
• If you are using 3M Super 77 on delicate materials, such as paper or fabric, be sure to test the adhesive in an inconspicuous area first. This will help you to determine the amount of adhesive that you need to use and to make sure that the adhesive does not damage the material.

I hope these tips help you to use 3M Super 77 Multipurpose Permanent Spray Adhesive effectively.

Which is stronger 3M 77 or 3M 90?

3M 90 is stronger than 3M 77. 3M 90 has a higher initial tack, which means that it bonds to surfaces more quickly and securely. It also has a higher shear strength, which means that it can withstand more force before the bond breaks.

Here is a table comparing the adhesive strengths of 3M 77 and 3M 90:

Adhesive	Initial Tack	Shear Strength
3M 77	120 lbs./in.	175 lbs./in.
3M 90	160 lbs./in.	250 lbs./in.

As you can see, 3M 90 has a higher initial tack and shear strength than 3M 77. This means that 3M 90 will bond to surfaces more quickly and securely, and it can withstand more force before the bond breaks.

However, it is important to note that 3M 90 is also a more permanent adhesive than 3M 77. This means that it can be more difficult to remove 3M 90 if you need to make a change to your project.

So, which adhesive is right for you? If you need a strong, permanent bond that can withstand a lot of force, then 3M 90 is the better choice. However, if you need an adhesive that is easier to remove, then 3M 77 may be a better option.

Ultimately, the best way to decide which adhesive is right for you is to consider the specific needs of your project.
