Open Cell foam and other porous substrates can present a challenge to adhesion if using a firm adhesive. Essentially, a firm adhesive will sit on only the top surface and can’t flow into the structure of the substrate. This results in decreased bond area and therefore bond strength. 300MP adhesive is specially designed around this challenge, the 300MP adhesive is soft enough to flow into porous substrates like open cell foams, textiles, mesh and wood.
