2 2 PU Adhesives Reactive PU PUR-HM 、 LPUR Solvent based 1K-PU PUM 、 PUD

3 3 PU Synthesis Moisture curing PU: NCO/OH>1

4 4 PU Synthesis  One Shot  Prepolymer

5 5 Isocyanate Toluene diisocyanate (TDI) Methylene diphenyl 4,4'-diisocyanate (MDI)

6 6 Solvent  Solvent base :Toluene 、 xylene 、 DMF 、 MEK 、 Acetone 、 EAC  Water base :H 2 O 、 MEK 、 Acetone

7 7 Additives  Catalyst (organic Tin)  Anti-oxide agent (1010)  UV absorber

8 8 Curing Mechanism wood

9 9 NCO% 1 NCO (MEK) + Et 2 NH (l) ( 過量 )  n Et 2 NH (MEK) 2 HCl (aq) + Et 2 NH (MEK)  Et 2 NH 2 + Cl - (MEK) 3 Et 2 NH (l), HCl (aq) 已知濃度  計算 NCO
