Polyurethane Sealant KT8

KT8 is a one-component polyurethane sealant
adhesive and sealing compound of permanent elasticity.
KT8 is a one-component polyurethane sealant
adhesive and sealing compound of permanent elasticity.It is based on a special moisture-cured polyurethane with an accelerated curing time.
Uses
High-speed railway,subway
Waterproof for the underground constructions and tunnels
Waterproof for toilet and basement
Waterproof for the constrction base
Advantages
*Excellent adhesion with former cleaned sealant
*Single Component, moisture-cured
*Excellent performance,easy to use
*High adhesion strength with all base materials
*Fast cure rate.
*Good weathering resistance and high durability.
*No pollution
*Can be painted
Instructions for use
Surface preparation
Clean all dirty, dust, loose particles and paint.Joints can be cleaned by compressed air. The filling material in the joints must be polythene.
Application
*Stick protecting adhesive tape on both sides of the joints.
*Insert filling materials.
*Use the sealant with manual caulking gun or aerodynamic caulking gun. Horizontal seal can be finished by spatula.
*Smooth with synthesized cleaner mixed by clean water if necessary.
*Tear off the protecting adhesive tape befor the sealant is curing.
*Clean all the tools after operating. The curing materials can be only cleaned by machinery methods.
