english Does low temperatures in winter affect the adhesion of marble protective film
2025-09-02
1. How Low Temperatures Affect Adhesion
- Low temperatures slow the activity of adhesive molecules in the protective film, reducing fluidity and weakening initial adhesion.
- Adhesive tends to harden at low temperatures, weakening its bond to the marble surface and making it difficult to form an effective bond quickly.
- This adhesion loss becomes particularly pronounced in extremely cold environments.
2. Adhesion Performance at Different Temperatures
- In mild and low-temperature environments, high-quality protective film maintains generally acceptable adhesion with minimal change.
- In extremely cold conditions, adhesion decreases significantly, potentially causing edge warping and difficulty securing the marble.
- If the marble surface temperature is too low, the adhesive cannot fully penetrate the contact surface, further reducing bond strength.
3. Material Adaptability to Low Temperatures
- Ordinary protective films have poor adaptability to low temperatures and experience significant adhesion loss.
- Protective films designed for low-temperature environments use a cold-resistant adhesive formula that maintains adhesion at lower temperatures.
- The adhesive backing of cold-resistant films retains flexibility at low temperatures and is less likely to lose adhesive strength due to extreme cold.
4. Methods for Improving Low-Temperature Adhesion
- Before application, moderately preheat the adhesive backing of the protective film.
- Use a low-temperature heat gun at a distance to soften the adhesive and restore its adhesive properties.
- Ensure the marble surface is dry and free of ice mist; wipe it with a dry cloth to warm it up before applying to enhance adhesion.
5. Precautions for Low-Temperature Application
- Avoid applying during extremely low temperatures; choose warmer daytime hours instead.
- Increase pressure during application and repeatedly press the film surface with a scraper to ensure full contact between the adhesive and marble surface.
- After application, place a heavy object on the edges and let them sit for a while, allowing the adhesive to gradually strengthen as it warms, reducing the risk of warping.
