Resin or hardener is a prepolymer with isocyanate group’s endings. The reaction is polyaddition occurs and as a result is a lattice structure of elastomeric polymers.
There are the reactions in which polyurethane is formed by the action of moisture:
Humidity + isocyanate + CO2 = amine groups;
Amine groups + isocyanate = polyurethane;
Specific features about PU 1C moisture using:
You should be accurate with skin formation time (action of moisture in the atmosphere that reacts with resin and forms the polyurethane), this time is the maximum period in which you have to apply adhesive and joi. Reaction can be accelerated using water irrigation after applying adhesive on the substrate, before joining.
Flexible and elastic materials;
Strength about 8 MPa to normal stress;
Elongation over 600%;
Poor resistance to UV radiation;
Can be painted;
Rarely need to use primers and activators to ensure adhesion;
Scope of use: sandwich panel production, PVC sandwich panels, HPL sandwich panel manufacturing, SIP sandwich panel, house building, gluelam manufacturing, I-Beam production, parquet manufacturing, multi layered parquet manufacturing.
