Blu Tack is a reusable putty-like pressure-sensitive adhesive produced by Bostik, commonly used to attach lightweight objects (such as posters or sheets of paper) to walls, doors or other dry surfaces. Traditionally blue, it is also available in other colours.
Spackle applied to a rough surface using a putty knife Spackling paste or spackle is a putty used to fill holes, small cracks, and other minor surface defects in wood , drywall , and plaster . [ 1 ] [ 2 ] Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue .
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
Light curing adhesives can cure in as little as one second and many formulations can bond dissimilar substrates (materials) and withstand harsh temperatures. These qualities make UV curing adhesives essential to the manufacturing of items in many industrial markets such as electronics, telecommunications, medical, aerospace, glass, and optical.
In wet slaking, a slight excess of water is added to hydrate the quicklime to a form referred to as lime putty. Lime is commonly used as a binding mortar in masonry due to its adhesive properties with bricks and stones. It is also used in whitewashing as a wall-coat to allow the whitewash to adhere the wall.
A matured lime putty is thixotropic, meaning that when a lime putty is agitated it changes from a putty into a more liquid state. This aids its use for mortars as it makes a mortar easier to work with. If left to stand following agitation a lime putty will slowly revert from a thick liquid to a putty state. [citation needed]
CaCO 3 is used in filler masterbatch as a base with a large percentage in composition. Calcium carbonate powder accounts for 97% of the composition will bring white/opaque products more whiteness.
