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 🙂
