Filler

Any substance in paste form, used to fill cracks and imperfections in wood or marble.

Filler

 

a pasty substance used in painting and varnishing to produce a smooth surface before the surface coat is applied. In addition to film-forming materials, fillers contain extenders such as chalk, talc, and barite as well as pigments such as zinc white and ocher. Fillers may have a varnish, drying-oil, or natural-adhesive base. Since the content of film-forming materials in a filler is 5–12 times lower than that of pigment or extender, fillers do not provide for a sure adhesion of the covering coats to the surface. For this reason, a filler is usually applied over a layer of primer.

A thick filler is applied with a putty knife or a piece of rubber. A filler thinned with small amounts of solvent may be applied with a pneumatic spray gun. The thickness of a layer of filler may reach 300 μ; when a filler is used to fill holes or to seal a joint or a riveted or welded seam, however, several layers with a total thickness of up to 1 mm may be required. The dried-up layer of filler must be sanded well with an abrasive paper. Varnish-based fillers are used mainly in the machine-building industry; fillers with a natural-adhesive or drying-oil base are used primarily in the construction industry.

filler

[′fil·ər]
(computer science)
Storage space that does not contain significant data but is needed to comply with length requirements or is reserved to fulfill some future need.
(materials)
An inert material added to paper, resin, bituminous material, and other substances to modify their properties and improve quality.
A material used to fill holes in wood, plaster, or other surfaces before applying a coating such as paint or varnish.
(metallurgy)
The rod used to deposit metal in a joint in brazing, soldering, or welding. Also known as filler metal.

filler

1. A fine mineral aggregate used as an extender to improve the properties of coating asphalt and plastic asphalt cement.
2. Finely divided inert material (such as pulverized limestone, silica, or colloidal substances) sometimes added to portland cement paint or other materials to reduce shrinkage, improve workability, or act as an extender.
3. A pigmented paste, sometimes colored, rubbed into open-grained wood surfaces to fill the pores prior to finishing.
4. An inert material added to synthetic resin adhesives to improve their properties or reduce cost.
5. A plate which is inserted merely to fill up space; a filler plate.
6. In painting, a composition (often pigmented) used to fill pores or irregularities in a surface in preparation for the application of another coating.

The breast walls coupling by means of the reinforcement concrete slab tie, the bracing of the bridge body filler and increasing the mutual interaction of the stone bridge structure with the bridge filler is an undesirable way of increasing the rigidity, and thus also the stress state of the bridge structure exposed to permanently present and cyclic mechanical stress states caused by changes in temperature and moisture content, as well as to processes which gradually degrade its mechanical resistance reducing the longevity of Charles Bridge [10, 11].
Theoretical analyses and the monitoring of deformations show that the increased rigidity of the bridge body filler and its interaction with the stone structure had a negative effect on the behaviour of the bridge structure contributing to its gradual mechanical disintegration.
A serious problem is a high moisture content of the bridge body filler resulting from rainwater leakage through the faulty damp proofing and its contamination by salts being the cause of chemical, biochemical and physical degradation processes deteriorating, step by step, the stone structure and impairing its service life.
Undressed arenaceous marl blocks only discretely joined together by lime mortar in bed joints, limited the intense interaction between the bridge body filler, the breast walls and the bridge vaults, namely in relation to the effect of cyclic deformations of the bridge arches (Fig 11) due to temperature and moisture effects, and thus the occurrence of predominantly transverse stresses preceding the appearance of longitudinal cracking on the underside of the bridge vaults.

Once the user is satisfied with the appearance of the body filler, the UV light would be used to cure the UV body filler to the perfect shape.
Due to the nature of being able to shape the body filler to the contour, less sanding and preparation of the repair needs to be done after cure.
Since the cure of the body filler does not take place until the UV light is exposed to the area, air trapped in the body filler, due to the application process, has time to be released out of the filler.
Some of the challenges of UV-cured body filler include:
With a body filler, shrinking of the film would affect adhesion and finish of the body filler.
