Customer Problem
1. Weak bond / Insufficient peel strength
Affected Parameters:
Bonding strength, initial tack, bonding substrate, open time
Customization Direction:
Based on the characteristics of different substrates such as paper, plastic, wood and fabric, adjust resin polarity, adhesive wettability and open time to improve bonding strength. Directionally adjust initial tack or long-term adhesion according to requirements.
Customer Problem
2. Glue flows too fast / too slow
Affected Parameters:
Melt viscosity, application temperature, glue application method
Customization Direction:
Based on the requirements of spray, dot, roller, glue gun or automated equipment application, adjust adhesive viscosity and flow state for more stable glue output and smoother application while keeping glue amount within the appropriate range.
Customer Problem
3. Softens in summer / Brittle in winter
Affected Parameters:
Heat resistance, softening point, low-temperature flexibility, cohesive strength
Customization Direction:
For summer heat, winter cold, transport and storage and different usage environments, directionally adjust the heat resistance, low-temperature flexibility and cohesive strength to reduce softening and debonding in high temperatures and brittle fracture in low temperatures.
Customer Problem
4. Curing too slow / too fast
Affected Parameters:
Open time, setting speed, crystallization speed
Customization Direction:
Based on production line speed, pressing time and operation window, directionally adjust open time and setting speed while preserving operation time, improving production efficiency and reducing waiting time and rework risk.
Customer Problem
5. Visible glue marks / Poor appearance on transparent materials
Affected Parameters:
Transparency, color, haze, adhesive cleanliness
Customization Direction:
For applications with higher appearance requirements such as transparent plastics, accessories, stationery and crafts, optimize adhesive transparency, color stability and low haze performance for a cleaner and more attractive bonding result.
Customer Problem
6. Severe stringing / Messy glue dots
Affected Parameters:
Melt strength, clean break, viscosity, application temperature
Customization Direction:
For dot gluing, spraying, glue gun or automated application scenarios, adjust melt strength, clean break behavior and rheological state to reduce stringing, tailing, dripping and overflow for cleaner glue dots and neater application edges.
