Expands to 10x Its Original Volume!

Every collision repair specialist can affirm the importance of foam in the automotive industry. 3M Automix Pillar Foam can expand up to 10x its original volume and is a two-part urethane product. This product is designed to flow and fill in required areas to add strength and reduce wind noise. The high expansion quality of this material allows you to use only small amounts of the material to fill in large cavities. 

Perfect for OEM replacement of rigid foams, you can use the 3M Automix Pillar Foam with the 3M 08117 applicator gun.

Foams have a large number of uses that include
  • Controlling noise and vibration
  • Providing added safety to passengers during times of collision
  • Making the body structure robust to prevent twisting and flexing
  • Keeps the vehicles light which can help in fuel efficiency

All modern vehicles make use of foam mainly to reduce the hollow, echoing sound that usually makes the automobiles noisy. During a collision, this foam may be damaged, and it is vital to put the foam back into place. This product from 3M mimics the sound dampening characteristics of OEM foam.

Key Features of the 3M Automix Pillar Foam:
  • Flows in easily and fills up to reduce wind noise in vehicles
  • Best used to replace OEM rigid foams and works very similar to the OEM foam
  • Expands easily up to 10 times its original volume
  • Only a small amount of product is required for a large area
How to use the 3M Automix Pillar Foam?
  • Cover adjacent surfaces with masking paper and temporary dams to make sure that the foam does not damage the other parts of your vehicle
  • Use the 3M 08117 applicator gun for application
  • You will have to connect the mixing nozzle with the docking collar and release a small amount before starting
  • Apply the foam in small quantity and wait for it to expand before going any further
  • Ensure that you do not have to trim the foam as the close-celled structure of the applied foam prevents moisture intrusion. If it is necessary to trim the foam, make sure that you use the 3M seam sealer
