We recommend that buyers prioritize the following characteristics before bulk purchasing: the 70u Hot Melt Double Sided Tape maintains stability at environmental temperatures ranging from 0°C to 50°C, with significantly faster initial tack compared to oil-based products, though its long-term tack retention is relatively limited. Procurement decisions should be based on specific application scenario requirements for tack retention, and customers may request samples for on-site testing verification. Bulk purchases can benefit from more favorable pricing strategies, and we advise aligning procurement plans with production needs for optimal efficiency.

Q1: How long can the initial adhesion of this 70u Hot Melt Double Sided Tape be maintained?
A: Initial adhesion takes effect immediately after application, providing rapid material fixation. However, for sustained stress conditions, we recommend completing the final curing process within 24 hours.
Q2: What is the best temperature for use?
A: The optimal operating temperature range is 15-30℃. When the temperature drops below 0℃, the adhesive's viscosity will significantly decrease. Exceeding 50℃ may cause the adhesive layer to soften, compromising bonding performance.
Q3: Which materials are not suitable for this double-sided tape?
A: It is not recommended for use on PP or PE plastic surfaces. Additionally, oily, wet, or powder-coated surfaces may compromise the bonding performance.
