PKSC 4300: Lamination Adhesives exam
1. What are the two broad type of adhesives?: - reactive adhesive
- non-reactive adhesive
2. What is a reactive adhesive?: an adhesive are created by the components will reacting together to
polymerize
3. What is a non-reactive adhesive?: an adhesive that is already polymerized
4. What is polyurethane's repeat unit?: urethane: created by the chemical reaction between iso-
cyanate and an alcohol
5. How is polyurethane made?: by placing an isocyanate at each group of the R groups and alcohol
groups at each end of the R'. This helps build the very long chain.
6. What are the R groups in isocyanate?: - often is toluene or methylene diphenyl
- the resulting chemical is either toluene di-isocyanate (TDI) or methylene diphenyl di-isocyanate (MDI)
- aromatic structures
7. What is aliphatic di-isocyanates: - non-aromatic versions of the R group in the isocyanate
