Question 1

What application methods are recommended for NSD-70 dextrin adhesive?

Accepted Answer

NSD-70 is optimized for roller, wheel, and nozzle application on high-speed packaging lines. Its 70% solids content delivers high initial tack and fast water release, making it suitable for spiral tube winding, carton sealing, and envelope gumming without requiring dilution under normal ambient conditions (20–25°C).

Question 2

Is NSD-70 compliant for food-contact paper and board packaging?

Accepted Answer

Yes. NSD-70 is produced from natural canary dextrin without synthetic crosslinkers or plasticizers and meets FDA 21 CFR 175.105 indirect food-contact requirements. It is also fully biodegradable, making it suitable for recyclable and compostable packaging substrates.

Question 3

How does open time and viscosity stability change with temperature?

Accepted Answer

Open time is typically 3–6 seconds at 22°C; elevated temperature (>28°C) shortens open time and reduces viscosity significantly — expect approximately 30–40% viscosity drop per 10°C rise. For summer production or heated environments, slight dilution with water (2–5%) or application-equipment cooling is recommended to maintain consistent bond performance.
