PVC glue


The best material for gluing plastic parts is PVC glue (polyvinyl chloride), which is used in construction, water supply, sewage, etc. The adhesion strength of this product is very high; The main mechanism of PVC glue is cold welding. The use of low-quality adhesives causes incomplete cold welding or very weak connection of pipes or parts to each other.

Connecting PVC pipes with this method will have a tight and leak-free connection like metal welding.

What is PVC glue?

Solvent-soluble PVC glue, the solvent is removed after gluing two pieces, and the connection is complete when the solvent is absorbed or evaporates.

Iran’s national standard regarding PVC adhesives is number 1174 (bs4346/3), which is set based on the American standard ASTM-d256, according to which PVC adhesive must include PVC without plasticizer and its specifications and characteristics are presented in the ASTM-d1787 standard.

The liquid should be uniform and have a medium viscosity (fluid), and if it has coarse and undissolved plastic particles and impurities, it will not have a good effect on the final connections of the parts and chemical resistance, and the PVC liquid should not turn into a gelatinous state.

Important note: Solvent liquid is not suitable for gluing soft PVC parts, such as artificial leather and coating sheets; Because there is a large percentage of softeners in them.

Important points

  • Be sure to use the national standard glue.
  • Connections should be cut correctly and accurately.
  • Follow the instructions in the safety manual.
  • Have the right speed in execution.
  • The tubes are rotated in each other.
  • After holding firmly for 25 to 30 seconds, allow it to dry for 30 minutes; Then put under load and pressure.

Tips for maintenance and implementation:

  • Be sure to stir before use.
  • Clean under the work surface.
  • Store in a cool and dark environment.
  • Postpone performance in hot hours of the day to cool hours.
  • Do not use at temperatures below 4 degrees Celsius.
  • The humidity level should be taken.

Applications of PVC glue

  • Construction and water supply purposes
  • Filling pores in plastic pipes
  • Repair of broken plastic pipes
  • As a sealant
  • PolIca pipes and fittings
  • Waste pipes and fittings
