(The results listed are based on tests run under controlled lab conditions. Since the ultimate use is beyond our control, these results are not guaranteed. Pre-testing should be conducted to confirm the application procedure using the actual substrates under true field conditions to ensure results are acceptable for the end use.)
Wipe the material surface with acetone or butanone to remove errors and moisture. Use two-component adhesive (add 5% curing agent). It is recommended to use German made adhesive.
Take an aluminum metal container (the glue bucket cannot be used as a container), weigh a certain amount of glue as required, and then add a certain amount of curing agent (it is not allowed to directly stir the curing agent into the glue bucket). For the unused glue and curing agent, the operator must immediately close the lid to prevent the water vapor in the air from entering and affecting the use effect.
Note: Generally, the ratio of glue and curing agent is about 100g: 5g, which can be adjusted to a reasonable ratio according to the actual operating experience of workers. Use an electric mixer to mix the glue for at least 3 minutes, so that the glue can be fully and evenly mixed with the original registered residence for standby. The mixed glue must be used up within 2-3 hours, otherwise it will become invalid due to the thickening and curing of the glue. When the operating humidity is high, the curing agent shall be increased as appropriate, and when the indoor temperature is high or in dry weather, the curing agent shall be reduced as appropriate. The mixing proportion of glue and curing agent is different in winter and summer, which shall be adjusted according to the actual situation.
Generally, it is coated by hand
Coating amount: 150-200g/m2 on one side, 200-500g/m2 on both sides
Drying time: 10 to 15 minutes at room temperature, extended in winter.
Align and bond the dry PVC bonding surface, and then heat it with hot air blower . It is related to the pressure bonding, the outlet temperature of the hot air blower is required to be greater than 100 degrees, and the temperature is related to the speed of the bonding degree.
The product can be stored for 6 months in a sealed container at a temperature of 5-30 ° C. At low temperature, this product is easy to thicken or solidify, and should be avoided as far as possible.
The PU GLUE is flammable and volatile. During transportation and storage, The pu glue should be kept away from fire sources, equipped with fire prevention equipment, and pay attention to ventilation and prevent open fire from contacting.
In case of fire, use fire sand, dry powder, foam, carbon dioxide and fire extinguisher to extinguish the fire.
Preventive measures for PU glue are important to ensure safe and effective use of the adhesive. Here are some key measures to consider:
When working with PU glue, it is advisable to wear appropriate PPE such as gloves, safety goggles, and a respirator. This protects the skin, eyes, and respiratory system from potential exposure to the adhesive and its fumes.
Ensure that the work area is well-ventilated to minimize the concentration of fumes. Open windows or use exhaust fans to improve air circulation and reduce the risk of inhalation.
Store PU glue in a cool, dry place, away from direct sunlight and sources of heat. Follow the manufacturer's instructions regarding temperature and humidity conditions for storage. Handle the adhesive with care, avoiding direct contact with the skin or eyes.
Before applying PU glue, perform compatibility tests on the materials being bonded. Some surfaces may require pre-treatment or priming to enhance adhesion. Follow the manufacturer's guidelines to ensure the best results.
Apply PU glue according to the recommended method and amount specified by the manufacturer. Avoid excessive application, as it can lead to longer curing times or weak bonds. Use appropriate tools and techniques for spreading or dispensing the adhesive.
Clean up excess PU glue immediately using suitable solvents or cleaning agents recommended by the manufacturer. Dispose of waste materials and empty containers according to local regulations and guidelines.
In case of accidental contact with PU glue, promptly wash the affected area with soap and water. If irritation persists or if the adhesive gets into the eyes or is swallowed, seek medical attention immediately.
