Whats the Same
Both traditional hot melt and polyurethane (PUR) hot melt typically need to be heated to be applied. They are both non-toxic and generally one of the safer adhesives for bonding and sealing.
Infinity Bond superPUR 60 offers a medium open time (60 seconds) but is still longer than traditional stick and bulk hot melt adhesives. SuperPUR 60 has a strong bond that continues to strengthen over time as it reacts with moisture in the air.
Traditional hot melt adhesives do not continue to strengthen after they have fully set. superPUR 60 requires a cartridge gun for dispensing and should not be exposed to air before being used. The shelf life is up to 2 years where traditional hot melts don't really have a shelf life.
