SANDING SEALER, LACQUER, PU WOOD COATING & VARNISH MANUFACTURING WITH FORMULAE

Sanding sealer is a liquid coat that seals wood and prevents the surface from absorbing varnish. It is a hard first coat that seals without obscuring the grain of the wood. It helps woodworkers achieve a smooth, even finish on a wood furniture. By design, sanding sealer serves as a “sandable” sealer, which means it can easily be sanded after application without impacting its effectiveness on the wood .

Sanding sealer is typically very thin, and dries very quickly to condition the wood in order to allow for less lean time. By applying sanding sealer during the finishing process, woodworkers minimize rough textures and create a smooth finish. Sanding sealers are used to eliminate stains. It can be applied over wood stain or bare wood, depending on the desired appearance, but before any protective coating or finish. This stains include those from water and fire damage. The sealer is then applied over the entire surface using a brush or foam pad after the stain is dried. The sealer must then be allowed to dry completely before proceeding to sanding. The surface is then sanded using a sanding paper before subsequent coats are applied. Sealers may be transparent and sometimes act as primers. Some sealers are designed to be left uncoated and thus can also be used as a varnish, however this is not recommended. Sealers are absorbed quickly by spongy woods, and this can prevent the formation of a film on the wood, leading to an effective seal. Sanding sealers contains zinc stearate, which helps it seal soft woods quickly and makes the wood easier to sand. However, if a lacquer finish is intended to be used above the sanding sealer, more than one or two coats should not be applied as a buildup of sealer can cause the lacquer to chip.

In the current market, most sanding sealers which have good drying capability have not been able to meet users’ requirements, prompting the present research study to attempt to calibrate the different qualities of the various available products, to produce sanding sealer of low drying time and also identify the raw materials that could be combined to obtain optimal sanding sealer formulation that would compete with already existing ones.

The  modern wax based polishes were first introduced as  wax solvent  paster  in  the late nineteenth  century  up  till  then floors, furniture and other surfaces were treated by a variety of methods  such  as scrubbing oiling sanding, varnishing and wood polishing. Waxes such as bees wax had been used long before  this for treating  wooden surfaces but these had  to  be  labourising applied by rubbering with a block of the material concerned later paster  of  bees wax is turpentine or emulsions of wax in soda solutions were used but these again required the expenditure or vasts amounts of time and energy to achieve  a  rates  factory surfaces gloss.

From today new manufacturing techniques and the inclusion of additives such  as silicone are continually  being  experimented with  to  improve  the finished product. Although a number of special wax polished have developed for application to specific surfaces such as footwear motor cars, furniture and floors,  two principal types of polish can be distinguished . There are  other process  in  which  the wax base is dissolved  in  a  non-aqueous solvent  (Paste  polished) and those in which the wax is  in  the form  of an aqueous emulsion (liquid polish). In both cases the waxes to be used are broken up i.e. crushes in crushing machine and then melted in steam or electrically heated pans.
