Adhesives are means of securing two surfaces together. They may be sold in solid, liquid, powder, or film form. Common types of adhesives include:
Animal or Fish Glues
-primarily for indoor use where temperature and humidity do not vary greatly
-may be weakened when exposed to heat or moisture
-made from boiling down bones
Casein Glue
-made from milk protein and is sold as a powder that is mixed with water just before being used
-good adhesion to porous materials
-moisture resistance is somewhat superior to animal glue
White Glue
-polyvinyl glue
-sets quickly and does not stain; slightly resilient
Contact Cement
-forms a bond on contact; does not require clamps
-generally used to secure large surface materials such paneling and countertops
-surfaces must be carefully pre-fit
Silicones
-withstand the highest temperature of all synthetic adhesives
-high moisture resistance
-used as binders for glass fibers used as insulation
Epoxy Resin
-extremely strong
-may be use to secure porous as well as non-porous materials such as metal and concrete; may dissolve some plastics
-unlike other adhesives, epoxy glues will set at low temperatures and under wet conditions
Resorcinol Resin
-strong, waterproof, and durable for outdoor use; flammable
-dark color may show through paint
-used on wood and other porous materials
-used to make exterior plywood
Urea-formaldehyde
-work best on porous materials; often used in wood-working applications
Putty
-a mixture of Linseed oil and finely ground calcium carbonate
-used to glaze wooden sash and fill small cracks and crevices in wood surfaces before painting
-dries and becomes brittle with age
-has no appreciable elongation value
Elastomeric-type compounds
-capable of elongations of 100% of more
-types include silicone mastics, butyl, neoprene, and hypalon rubbers, vinyl chloride polymers, poly sulfide polymers, butadiene-styrene co-polymers
Mastic-Type Compounds
-oxidizing type
