Tung oil is derived from the nuts of tung trees - Aleurites fordii - native to east Asia. A quality first pressed tung oil is a pale gold brown in colour and has a viscosity somewhat greater than a heavy olive oil. Pure tung oil is foremost among a group of auto oxidising, unsaturated oils which are tung oil for sale nyonya interest to tung oil for sale nyonya finishers.
These oils harden on contact with oxygen to offer the classic, beautiful, natural oiled finish suited to numerous uses of wood. USES Tung oil has a very wide range of uses including on bee hives, horse stable enclosures, timber flooring, cabinetry, architectural joinery exterior and interiortung oil for sale nyonya structures and furniture, gun stocks, didgeridoos, kitchen wood-ware and bench tops, rammed earth and stonework.

These finishes divide further into those which can be reformulated on Tung Oil For Sale the fly, where the newly applied finish can meld with the prior coating, for example lacquer and shellacor those modern varnishes which polymerise cross link and which have to be removed, or at least heavily scuffed sometimes referred to as giving the surface "tooth"to provide a key for subsequent coats or touch up.
It is precisely this final stage inertness and imperviousness resulting from the completion of the cross linking chemical bond formations that makes these modern polyurethanes - either moisture or catalyst cured - so resistant and tough. They do however usually scratch rather easily. Oil finishes by comparison, for whatever end, flooring, cabinetry etc, are by nature more penetrative and mostly "in the wood" whereas membrane or skin finishes typically sit on the wood and key with the wood with a lesser degree of penetration.
Oil finishes can be regarded as preserving the look and feel of the wood better than skin finishes which, critics would say, put a plastic coating on the wood. The precise ingredients and their proportions is typically proprietary information.
Tung oil remains an expensive ingredient so many of these commercial formulations contain a limited amount of tung and use cheaper non drying extender oils which then require toxic dryers and anti fungal additives.
As a general statement nut oils derived from trees are, for wood finishing purposes, more robust than seed oils, e. The tree nut or seed oils of particular interest to wood finishing are those which have a "drying" characteristic.
They include Linseed both Raw and so called Boiled, which is, these days, usually raw with chemical dryers addedwalnut, poppy seed and tung oils. These oils can be classed as unsaturated drying oils and it is this characteristic which makes an oil of interest to wood finishers. A drying oil is an oil which hardens to a tough, solid film after a period of exposure to air. The term "drying" is a misnomer - the oil does not harden through the evaporation of water or other carrier solvents as do many skin finish formulations, but through a chemical reaction in which oxygen is absorbed from the environment autoxidation.
Oil finishes can be remarkably tough, are usually superior in the patination stakes and the initial application, touch-ups or re-coats are far less problematic than with membrane finishes. Membrane finishes frequently crack when damaged and this allows penetration of moisture and dirt into the ding or crack which then discolours. Oil finishes have little skin to worry about and thus suffer less from the delamination due to dings and natural seasonal wood movement which is a given for all solid wood in service outside of air-conditioned environments.
They therefore patinate better. Patina defined - the appearance of a piece, including dents, dings and the aged finish and, while mostly applied to cabinet pieces, also applicable to floors and window and door trim.

The high grade pure tung we sell has a viscosity akin to olive oil and in most cases should be thinned before use. We recommend Citric Terpene d-Limonene which is distilled from orange and mandarin skins and, when more highly refined, is used as a food flavour.
A cut with Citric Terpene is our recommended mix however this is frequently adjusted a bit each way to speed penetration in ultra hard or highly absorbent woods. If harder thin more, if very thirsty you can thin less. Overdoing It We have had a few customers who were so delighted tung oil for sale nyonya the result from 1 coat they assumed 50 coats would be even better!
There would be few instances where more than about 4 coats are called for. Too many coats may begin to form a membrane which is not called for with oil finishes.

This pallette will enable you to adjust the oil colour. The most compelling advice regarding the use of these dyes and stains is to measure carefully, test mix ratios and procedure carefully and document what you do so that a successful outcome can be replicated.
See HERE for graduated storage and mixing containers. VOC Pure tung itself has a zero VOC rating volatile organic compound - the off gassing compounds found in petrochemically derived thinners which are both deleterious to the atmosphere and often hazardous to breathe or come into contact with. The gases given off by Citric terpene are in fact the same as nature off-gases from orange orchards which suggests it is a more benign product to thin tung with.
Note there are several grades of both tung and terpene - we sell the palest best quality of tung and a high quality water-white grade of terpene.
If Citric Terpene is not available Gum Turpentine, also a tree derived product, is a good alternative.
