FAQ

Q1: What's the key difference between this 80u Hot Melt Double Sided Tape and the 70U model?

A: The 80U model demonstrates superior initial adhesion compared to the 70U, ensuring more reliable initial fixation while also reducing the time required for operational adjustments.

Q2: How effective is the product in low temperature environment?

A: The initial adhesion may decrease when used below 0℃. For optimal performance, we recommend operating at 15-30℃.

Q3: Which materials have the best surface effect?

A: It works best on porous materials such as paper, cardboard and wood, and also has good adhesion effect on smooth surfaces such as plastic and metal.
