Technology Post #5
This week we learned about adhesives. Adhesives are used to stick things together. Adhesive are made of polymers or resins.
Types of Adhesives
1) Pressure Sensitive- they don’t need solvent, water or heat to stick.
(ex- tape)
2) Polymer- great for bonding with wood and also food packaging, and the autonomic industry.
(ex-super glue)
3)Dextrin-a thin glue made from starch to hold the pages of books
4) Polyvinyl Acetate/ PVA – the white glue we use in classrooms
5) Reactive- used to bond cell phones and computers
6) Solvent-based- a liquid combined with polymerase that is found in post it notes
Thank you, Caterina 🙂
