Description of polyurethane sealant

SATOP® 3130 is a medium strength, multi-purpose one component polyurethane sealant. The product solidifies by reacting with moisture in the air. After curing, it forms a permanent elastomer, advantages are high bonding strength, good toughness, vibration resistance, anti-low temperature resistance, surface coating, easy construction and so on.

Typical application of polyurethane sealant

Suitable for adhesion and sealing of various materials. It can be used in automotive, Marine, rail transportation, aerospace, engineering machinery, electrical and electronic industries, such as bond, seal and fill manufacturing process of Windshield, side window, panel skin, profile structure, etc.

USE of polyurethane sealant

  1. All bonding surfaces must be clean, dry, free of dust and oil spotsand any other material that affects bonding.
  2. Cut nozzle to give the required angle and bead size, Pierce the membrane at the top of the cartridge and screw on the nozzle. Place the cartridge in an applicator gun and squeeze the trigger with equal strength
  3. Ensure that the sealant is in good contact with the bonded surface, please modify before surface curing. Once the package is opened, it must be used up in a relatively short time.
  4. Finish scrapingand finishing before surface dry.
  5. Operating environment temperature is 10 ~ 40 ℃


Attention of operation

  1. Please spray painted after surface dry. compatibility test should be done before spray painting. Glue must be fully cured before exposure to baking temperature.Otherwise, there might be bubbles.
  2. UncuredSATOP® 3130 can be removed from the tools or equipment with appropriate If sealant has been solidified, it can be removed using a scraper or other mechanical device.
  3.  Please use suitable industrial liquid soap and water to clean Immediately when hands and exposed skin touch sealant.
