Lejell 230 is a one component gun grade polyurethane based construction sealant, it is of high modulus and cures by reaction with atmospheric moisture to form a soft rubber like material with high adhesion strength...
Lejell 230 is suitable for place where strong adhesion strength is required.
* Joints in the construction industry, particularly where a higher modulus and lower movement capacity are required for joints with low or medium movement.
* Connection joints between floor/stairs and wall.
* Connection joints between floor and machinery.
* Seam sealing / sealing of pipe ducts / ventilation systems.
* Multi purpose in metal and wood construction work.
* mildew proofing, Meet national standard for sealing of drinking water pipe.
* One component, no need of mixing.
* Easy for applying.
* High adhesion strength.
* Excellent durability, weathering resistance...
* Self bonding, easily for repairing.
* three kinds of colour available.
* 600, 400 CC aluminium foil packaging, 310 cartridge package for choice.
* Can be painted.
* For common occasion, after cleaning out the surface with organic solvent, this product can be used directly.
* Please construct by application instructions strictly, failure of stickiness may be caused by any
Operation disobeying construction techniques.
* This product is innocuous after curing completely, but before set, please avoids contacting with eyes and skin. In case of eyes and skin contact, wash immediately and thoroughly with soap and water. See doctor immediately if it is serious.
