Frequently Asked Questions
What is the recommended operating temperature for HM-253?
The recommended operating temperature is between 160°C and 180°C. You can adjust the viscosity depending on the season by lowering the temperature by 5-10°C in summer or raising it by 5-10°C in winter.
What are the temperature limits for application and service?
The adhesive should be applied to labels at temperatures between +15°C and 50°C. Once applied, the temperature resistance of the label ranges from -20°C to +60°C.
How do environmental factors affect the adhesion performance?
Performance can be affected by the substrates, release paper, and application environment. It is crucial to ensure surfaces are free of dust and oil, and that substrates and release paper are conditioned to constant temperature and humidity before use. A trial run is highly recommended.
What safety precautions should be followed during application?
To avoid scalds, operators must wear safety glasses, safety gloves, and safety clothing. Additionally, do not mix HM-253 with other adhesives, keep containers covered to prevent contamination, and turn off the heat if the adhesive will not be used for an extended period to prevent carbonization.
What makes HM-253 suitable for PVC flooring?
HM-253 offers excellent initial tack, holding power, and high peel strength. It also features outstanding heat resistance, low odor, light color, and anti-plasticizer and anti-aging properties, ensuring a durable, aesthetic, and long-lasting bond.
