Supex PU 40 Polyurethane sealant

Supex PU 40 polyurethane sealant an organic material used for sealing and bonding. Its properties like resilience, flexibility, bond strength, UV resistance, hardness etc can be modified as per application requirements.

Sealing

Used in joints between prefabricated building elements, in joints of rainwater collection pipes on roofs and in rain gutters, insulating joints between precast concrete blocks and sealing of joints of aluminum pipes in HVAC (ventilation) sector.

Bonding

Especially used in automotive industry, in the manufacture of vehicles, in the sealing of metal structures such as containers and trucks, in the manufacture and installation of air conditioning in HVAC systems, in order to reduce vibration and provide sealing in metal sheet joints.

Supex PU 40 polyurethane sealant, developed for India, is a high-quality multipurpose non-sag one-part Polyurethane sealant that cures on exposure to atmospheric moisture to form a durable elastomer. Supex PU 40 has been especially developed for Indian subtropical conditions. Most suitable in high temperature & extreme humid conditions. Usage mostly in Bonding & sealing for Bus Body, Rail Coaches, expansion joint sealing and other automotive / construction applications.

How to use PU sealants 

  • Before application, make sure that the surface is free from dust and grease. This will otherwise inhibit the process of application of the sealant.
  • We recommend that you conduct a preliminary compatibility test before proceeding to use the sealant for its desired purpose.
  • Apply the sealant evenly. If required, use masking tape to mark the areas of application. Before it cures, make sure to remove the tape.
  • The ratio of the joint width to the depth ratio should be 2:1.
  • Further, it is recommended to use a backup material if you feel like joint adjustment is required.
  • You may use backer rods and bond breakers to facilitate the adhesion. It should adhere only to two surfaces of the joint.
  • Take care to follow the standard industrial application procedures. Clean the fun after use before giving the sealant time to cure.
