Understanding PUR Hot Melt vs Traditional Hot Melt

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. 

• Non-toxic
• Applied by heating and dispensing

Whats Different

Infinity PUR 250-180 offers a long open time (180 seconds) much longer than traditional stick and bulk hot melt adhesives. PUR 250-180 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. PUR 250-180 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.

• PUR hot melts can offer longer open time.
• They have a much stronger bond than traditional hot melt.
• PUR has a shelf life of 12-18 months.
