-‘putty’ is a ‘material’ with high ‘plasticity’-
*similar in ‘texture’ to ‘clay’ or ‘dough’*
*typically used in ‘domestic construction/repair’ as a ‘sealant’/’filler’*
.
Although some types of putty (typically those using linseed oil) slowly polymerise and become stiff, many putties can be reworked indefinitely, in contrast to other types of filler which typically set solid relatively rapidly
.
Use in construction
Putty has been used extensively in glazing for fixing and sealing panes of glass into wooden frames (or sashes), although its use is decreasing with the prevalence of PVC and metal window frames which use synthetic sealants such as silicone.
Glazing putty is traditionally made by mixing a base of whiting (finely ground chalk) with linseed oil in various proportions.
Historically, white lead was sometimes mixed with the whiting
There are a number of synthetic alternatives such as polybutene-based putties, where the polybutene is a low molecular weight oligomer replacing the ‘linseed oil’
Butyl rubber is also added to the mixture to provide some strength and flexibility.
Painter’s putty is typically a linseed oil-based product used for filling holes, minor cracks, and defacements in wood only.
Putties can also be made intumescent, in which case they are used for firestopping as well as for padding of electrical outlet boxes in fire-resistance rated drywall assemblies.
In the latter case, hydrates in the putty produce an endothermic reaction to mitigate heat transfer to the unexposed side
In woodworking, water-based putties are more commonly used, as these emit very little odour, are more easily cleaned up and are compatible with water-based and latex sealers.
Plumber’s putty is the common name encompassing a variety of products of completely different compositions, all used for making watertight seals in plumbing.
Polyester putty and epoxy putty are plastics that can be molded by hand but become stiff and hard after curing.
Pratley Putty is an epoxy putty used primarily for steel bonding.
Milliput is another epoxy putty.
Bondo is a polyester putty.

Other uses
Certain types of putty also have use in the field of terminal ballistics, where the putty can accurately represent the average density of the human body.
As such it can be used, for instance, to test the penetrative power of projectiles, or the stopping power of body armour.
Modeling clay and play putty, such as Plasticine and Silly Putty are common toys.
Silly Putty comes packaged in plastic eggs
