Application
Its adhesion performance will be affected by substrates, release paper and application environment, so trial run is necessary to determine whether the adhesive is suitable.
There should be no dust or oil on the surface of substrates and release paper, also the substrates and release paper should be treated to constant temperature and humidity before application.
Application Methods: Roller or Spray
Operating temperature: The 165-175℃ is recommended. The glue viscosity can be adjusted by the temperature: appropriate down 5-10 ℃ in summer, raised 5-10 ℃ in winter.
Warnings
- Don’t mix the product with other adhesives.
- Keep the adhesive containers covered to avoid dust or contamination.
- Stop heating if you don’t use it for a long time to avoid the carbonization of the adhesive.
- Wear safety glasses, safety gloves and safety clothes when using hot melt adhesive to avoid scald.
Advantages
HM-2270 adhesive provides excellent loop tack and retention, ensuring labels stay securely in place after application. Its balanced peel strength allows labels to be easily removed when needed without leaving any residue. This makes it ideal for products that require labels that can be easily replaced or updated.
One of the outstanding features of HM-2270 adhesive is its excellent die-cutting performance. This means labels can be precisely cut into a variety of shapes and sizes without compromising the integrity of the adhesive. This makes it an excellent choice for custom label requirements, allowing for unique and eye-catching label designs.
In addition, HM-2270 adhesive has excellent low temperature and aging resistance, ensuring labels remain intact and legible even in harsh environmental conditions. This makes it a reliable choice for products stored or used in cold or harsh environments.
Whether you are in the food and beverage, pharmaceutical, or consumer goods industry, HM-2270 Pressure Sensitive Hot Melt Adhesive for Labels is a versatile and reliable choice for all your labeling needs. Its exceptional performance and durability make it a valuable addition to any production line, ensuring your products are labeled effectively and attractively.
Frequently Asked Questions
What is the recommended operating temperature for this adhesive?
The recommended operating temperature is between 165°C and 175°C. Depending on seasonal conditions, you can lower it by 5-10°C in summer or raise it by 5-10°C in winter to adjust the viscosity.
What are the primary physical properties of HM-2270?
HM-2270 is a non-toxic synthetic resin adhesive with a yellow translucent appearance. It has a Ring & Ball softening point of approximately 105°C and a density of 0.98 g/cm³.
How does the viscosity change with temperature?
Its Brookfield viscosity is temperature-dependent: approximately 10,000 mps at 165°C, 7,200 mps at 175°C, and decreases to about 5,200 mps at 185°C.
Can HM-2270 be used for labels that require clean removal?
Yes. Its balanced peel strength ensures that labels hold securely but can still be easily removed when necessary without leaving behind sticky residue.
What preparation is needed before applying the adhesive?
The application substrates and release paper must be completely clean, free of dust and oil, and pre-conditioned to constant temperature and humidity before starting application.
What safety precautions should be taken during use?
Always wear safety glasses, gloves, and protective clothing to avoid thermal scalds. Do not mix it with other adhesives, keep containers covered to prevent contamination, and turn off the heat when idle to prevent carbonization.
