2. DEscriptION:
Lejell 220 is a multifunction gun grade polyurethane basedconstruction sealant, it is of high modulus and cures by reactionwith atmospheric moisture to form a soft rubber like material withmoderate elasticity and hight adhesion strength.
3. USES:
·Suitable for joints where high resistance to penetration andpressure are required.
·For joints where low movement capacity are required.
·Joints in paving,airport and bridge runway.
·Seams on water pipe(back to water).
4. ClEANING:
Clean and dry all surfaces by removing foreign matter andcontaminants such as oil dust, grease, frost, water, dirt, oldsealants and any protective coating. Dust and loose particlesshould be cleaned.
