Description of pu sealant

SATOP® 3140 is a high viscosity, high performance high strength, one-component pu sealant. The product solidifies by reacting with moisture in the air. After curing, it forms a permanent elastomer, advantages high bonding strength, good elasticity, aging resistance, shock and fatigue resistance, low temperature resistance, surface coating, easy construction and so on.

Typical application of pu sealant

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

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. Finish bonding construction in the dry time.
  3. UncuredSATOP® 3140 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
  4. Please use suitable industrial liquid soap and water to clean Immediately when hands and exposed skin touch sealant.

 

USE of pu sealant

  1. All bonding surfaces must be clean, dry, free of dust and oil spotsand any other material that affects bonding.
  2. On the two surfaces of adhesion, need to clean treatment with SATOP®3100 cleaning ag After the solvent evaporates, Brush SATOP®3110 primer coating on the face.
  3. 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
  4. Operating environment temperature is 10 ~ 40 ℃
