Our Paper Honeycomb Fire Rated Door Glue is engineered to create a bond so strong that it can withstand the harshest of conditions. When bonding paper honeycomb cores and steel plates, it forms a connection that not only ensures the structural integrity of the fire - rated door but also plays a vital role in maintaining its fire - resistant capabilities. Whether it's for a high - rise commercial building, a cozy residential home, or a bustling industrial facility, fire doors bonded with our glue stand as a reliable shield against the ravages of fire.
Appearance: A dark brown or brown sticky liquid, signifying its ready - to - use and high - quality nature.
Working Time: With a 30 - minute window, manufacturers have ample time to work with the glue, ensuring precision in application and assembly.
Initial Cold Press Time: Just 3 hours of initial cold pressing gets the bonding process off to a quick start, reducing production time without compromising on quality.
Basic Cure Time: In 24 hours, the glue reaches 90% dryness, providing a stable and durable bond that can be further processed.
How to Use and What to Consider
Surface Cleaning: Start by thoroughly cleaning the surfaces of the paper honeycomb core and steel plate. Remove any dust, grease, or contaminants. A clean surface is essential for a strong bond. You can use a cleaning agent and a lint - free cloth for this task. Slightly sanding the surfaces can also improve adhesion, but be careful not to damage the materials.
Glue Application: The single - component polyurethane glue is ready to use right out of the container. Use a brush, roller, or a proper dispensing tool to apply the glue evenly on the surfaces to be bonded. Make sure to cover the surfaces completely, but don't apply too much glue, as this can cause oozing and longer curing times.
Assembly and Pressure: After applying the glue, quickly bring the paper honeycomb core and steel plate together. Align them accurately to ensure a perfect bond. Apply gentle pressure to ensure good contact between the glued surfaces. For the best results, use a cold press and apply [recommended pressure value] for 3 hours during the initial cold press time. This will help the glue start setting and form a strong initial connection.
Curing: After the initial cold press, let the glued assembly cure in a well - ventilated area. The basic cure time is 24 hours, during which the glue will reach 90% dryness. Avoid moving or stressing the assembly during this time. Remember, the curing time can be affected by temperature and humidity. In colder or more humid conditions, the curing process may take longer.
Storage: Store the glue in a cool, dry place, away from direct sunlight and heat sources. The ideal storage temperature is between [optimal temperature range]. Keep the container tightly closed when not in use to prevent moisture from getting in, which can affect the glue's performance. The shelf life of the glue under proper storage conditions is [shelf life duration].
Safety Precautions: This glue contains chemicals that can be harmful if ingested, inhaled, or if they come into contact with the skin or eyes. When handling the glue, always wear gloves, safety glasses, and a mask. If the glue gets on your skin, wash the area immediately with plenty of soap and water. If it gets into your eyes, rinse them thoroughly with water for at least 15 minutes and seek medical attention right away. Do not let children or pets near the glue.
Compatibility Check: Before using the glue on a large - scale production run, it's a good idea to test it on sample materials first. Although our glue is designed specifically for paper honeycomb cores and steel plates, different grades or coatings of these materials may react differently.
