Ductless Benchtop Spray Hood for 3M Super 77 Multipurpose Adhesive Spray Fume Control
3M Super 77 Multipurpose Adhesive Spray is used regularly in a variety of creative industries, including graphic design, advertising, model-making and architectural firms, product packaging companies, printing shops, and more.
Because this product is so useful and may be used practically everyday in some businesses, the health effects associated with it are often overlooked. In reality, your exposure to this product and other epoxy aerosol sprays should be monitored and controlled on a continuous basis (even if you only use it from time to time).
You’ll notice that ill health effects can occur through several points of entry: eye contact, skin contact, inhalation, and ingestion. Additionally, it mentions the organs that are most likely to be effected.
If you continue on to SECTION 8 of the MSDS, you’ll find the EXPOSURE CONTROLS/PERSONAL PROTECTION section. This section provides recommended engineering controls that you can implement to help protect yourself from the hazards of this particular adhesive spray.
Section 8.1 recommends using this product with local exhaust ventilation in a well-ventilated area.
One example of local exhaust ventilation is a benchtop spray hood. Some benchtop spray hoods can be exhausted outdoors via ducting, but depending on your location, city regulations may not allow you to vent this type of aerosol outdoors. Furthermore, many offices in high-rise builings simply don’t have the option to duct outside. External venting maintenance can also become costly, as ductwork may become clogged and require frequent cleaning or repair.
To avoid these issues, you might consider a Ductless Spray Booth, which is equipped with specialty filtration media that captures hazardous overspray and fume and therefore does not require exterior ducting.

Local Exhaust Ventilation: Ductless Spray Booth
As illustrated below, Ductless Spray Booths are designed to quickly capture and contain overspray generated inside the hood. It then travels through the internal spray filter, which captures most of the overspray. It then travels through the HEPA Filter (up to 99.97% efficient on particles 0.3 microns and larger) to remove the remaining spray particles, and then moves through the Activated Carbon Filter, which filters out VOC’s and solvent vapors.
This configuration helps to protect the respiratory zone of the operator by quickly capturing contaminants and directing them into the filtration system. This unit can also help limit eye contact with overspray by offering significant containment. Ductless Spray Booths also help to protect expensive equipment that may be in the immediate area (e.g. computers, printing equipment).
Additional engineering controls should be utilized to avoid skin contact and ingestion. Suggestions are given in the MSDS for the featured product. [If you are utilizing a different adhesive or epoxy, you should acquire the specific MSDS for that product. The manufacturer should have this information available for you].
