Answers
Binder - Answer-forms a coating when it dries that traps pigment particles to the surface
Additive - Answer-help all parts of the paint to work together
Volatile - Answer-help polymerization to occur
Paint Types - Answer-watercolours
egg tempera
acrylic
oil paints
Drying Process - Answer-Oil or fat molecules contain chains of carbon atoms.
Unsaturated fats have a double bond, which makes it easier for them to form bonds with
other fat molecules.
Monounsaturated - Answer-one double bond
Polyunsaturated - Answer-many double bonds
Drying oils - Answer-polyunsaturated (linseed, poppy)
Paint Components - Answer-binders
pigments
volatile substances
additives
Pigments - Answer-give paint colour
Polymerization - Answer-Neighbouring oil molecules bond with each other (at the sites
of the C=C double bonds) and also to the surface
In this way the cross-linked structure that forms (called a polymer) traps pigment
particles to a surface
