The biggest difference between a semi-transparent stain and a solid stain is the opacity. Semi-transparent stains are pigmented stains that impart some color on the wood while still allowing some of the grain of the wood to show though. Solid stains are opaque stains with lots of pigment covering the wood grain.

With a semitransparent stain, which illustrate the effect of pigment concentration. Adding percent iron oxide pigment to a linseed oil-based semitransparent stain formulation produced a semitransparent stain that re-duced the erosion rate of western redcedar by 31 percent and southern pine by 4 percent (Table 1).

Weathering and Surface Protection of Wood. ROLE OF PIGMENT CONCENTRATION IN THE WEATHERING OF SEMITRANSPARENT STAINS. These results show that higher amounts of pigment in a semitransparent.
Generally, the greater the pigment concentration (that is, the greater the opacity), the greater is the protective role of the coating.1 Clear coating systems have become popular due to their ability to enhance the aesthetic properties of the wood.
Semi-transparent stains contain pigments that partially obscure the wood surface and hence they reduce the amount of light reaching the wood. At pigment concentrations of %, stains reduce wood Role of pigment concentration in the weathering of semitransparent stains book caused by weathering by 65%.Cited by: nas.
Yellow Iron Oxides are know as Ochre, and it is this color that Germany derived it's Dunkelgelb color to paint it's pan-zers starting in Pigments are dry powders that when added to oils, binders, and thinners create paints and stains.
Now you that you know the background, the part we really care about is using it with our Size: KB. The higher values of ΔE for both treated and untreated samples were associated with the weathering cycle with the water spray step, suggesting that water plays an important role in the wood.
Feist W C, Role of pigment concentration in the weathering of semi-transparent stains’,Forest Prod J,38, (2), 41–44, CAS; Google ScholarCited by: An exterior stain job can last from 5 to 15 years, depending on your location, the work's exposure and the quality of the stain. It's possible to stain over existing stain and much easier than painting over it.
As long as you clean and prepare the surface properly, you can do another long-lasting stain job. Solid-color stains are made with a higher concentration of pigment than are the semitransparent penetrating stains, but a somewhat lower concentration of pigment than that of standard paints.
As a result, solid-color stains obscure the natural wood color and grain, and they can also be applied over old paints or solid-color stains. Feist WC () Role of pigment concentration in the weathering of semitransparent stains.

Concrete powder colorants included powder release, color additive, color hardener products and also iintegral color bags for coloring fresh ready mix new concrete pours.
The wood cell walls and the distribution of the resin and pigment were clearly visualized at the same time. It was concluded that confocal Raman microscopy is suitable for the evaluation of the microdistribution of wood coatings, providing valuable information for the improvement of wood coating by: 1.
The Semi-Transparent stains have a high pigment loading as opposed to the Transparent stains, providing a “hiding” effect, hence the term Semi-Transparent.
Transparent stains use expensive Trans-Oxide pigments which have been known to block U.V. light as well and allow for the “transparent” look, but have limitations due to the lower. Stains are divided in three different categories: transparent, semi-transparent, and solid colour stains.
Transparent or clear stains either do not contain any pigment or contain nanopigments. Because clear stains do not have any pigment they need other types of UV stabilizer or blocker to be able to protect the wood from UV : Mojgan Nejad, Paul Cooper. with a lower pigment concentration to allow textures to show through.
They perform similarly to paints but require more frequent maintenance. Semitransparent stains provide much less protection from both moisture and light, and must be reapplied more frequently than the paints and heavier stains.
However, surface preparation and. Pigment Volume Concentration (PVC) Looking past refractive index as a main cause, a more promising possibility is that the changes are driven by differences in the Pigment Volume Concentration (PVC), defined as the ratio of the volume of the pigment divided by the volume of both pigment and binder together.
pigment concentration, binder system, and additives may affect the ability of a finish to prevent release of CCA components. One report indicated that a clear water repellent finish greatly decreased CCA release from fencing (13). Even after 2 years, arsenic concentration in.
Semitransparent stain provides a color without entirely concealing the color, grain, and texture of the wood. Stains with the highest pigment concentration. FINISHING WESTERN RED CEDAR SIDING - CLEARS, SEMI-TRANSPARENT STAINS, BLEACHING OILS By William C.
Feist. Quite often Western Red Cedar (call it “cedar” for short) users prefer a finish that preserves the natural color and appearance of cedar.
However, there is no easy way to maintain the natural. The book deals with fundamentals of paints, Varnishes and lacquers, pigments, Oils used in paints and varnishes, solvents, dryers, plasticizers, additives for surface coating, various types of paint manufacturing. Role of pigment concentration in the weathering of semitransparent stains.
Forest Prod J. Forsthuber, B. and G. Grull. The effects of HALS in the prevention of photo-degradation of acrylic clear topcoats and. At set intervals the coatings were photographed and examined for evidence of chalking (DIN ) and colour change (DIN ).
Effect of the binder type and pigment volume concentration This series should investigate the effect of binder type and PVC in mat masonry paints. A useful measure of weathering resistance is the extent of chalking. The benefits of inorganic pigments are discussed, deriving a direct correlation between UV opacity, accelerated weathering and lifetime.
In the blue color space, pigments have been tailored to optimize color, tinctorial strength, visual/ultraviolet opacity and weatherfastness, therefore providing a cost-effective, high-performance coloring.

A single coat of semi-transparent stain most affects light-colored, neutral tones. Dark and bright wood tones are less changed. You might be best served by buying small sizes of stain and testing the color on scrap pieces of your siding.
The problem can be that a quart might be the smallest size available. Modern Technology Of Paints, Varnishes & Lacquers (2nd Edition) by Niir Board, ISBN:Rs.
/ US$. Clear and lightly pigmented finishes (such as semi-transparent stains) permit exposure of the wood surface to some ultraviolet (UV) light. As this light degrades the surface of the wood, the durability of the finish is decreased.
The durability of wood stained with semitransparent stain parallels that of unstained wood. However, wood surfaces. The aim of this study was to investigate effects of natural weathering on color stability of Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis L.) impregnated with some chemicals [tanalith-E (TN-E), adolit-KD5 (AD-KD5), and chromated copper arsenate (CCA)] and then varnished [synthetic varnish (SV) and polyurethane varnish (PV)].Cited by: These stains add more color, while still showing the natural grain variation and wood color.
Semi-transparent stains are available in a variety of colors, with an acrylic finish that is available in one or two coats. Layer thickness of semi-transparent glazes and pigment concentration affect the visual perception of fading, along with the relative tinting strengths of red lakes in combination with other pigments.
Differences between the four lakes tested were most detectible in samples containing white or blue pigments, in which lac lake tended to retain. Coating surface morphology changes were investigated by gloss and color measurements, as well as SEM and AFM.
Along with the investigation of the general degradation of the coatings, the effects of pigmentation on coating durability. Apply the colour unevenly and in a splotchy pattern.
This will keep the weathering from looking too uniform and increase the realism. Next I apply Clay Brown in dense, uneven sections. This creates the look of dry mud or sandy dirt. You can already see the weathering pigments bringing out the detail in the tank tread. Stain opacity levels range from clear to solid, with the amount of pigment in a stain determining its opacity.
Translucent, Semi-Transparent, and Semi-Solid Stains are designed to protect without completely obscuring the natural color and texture of wood. As the opacity moves towards solid, less grain shows through the finish. In contrast.
A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits materials selectively absorb certain wavelengths of light.
Materials that humans have chosen and developed for use as pigments. Used for staining concrete walls, floors including cast concrete products and overlays. New forEco-Stan is now available in a concentrated liquid 32oz. bottle that makes one full gallon and a oz. bottle. Offered in 30 UV stable concrete stain colors, EcoStain can be diluted up to to create virtually any color stain color : $ How quickly chemical weathering breaks a rock down is directly proportional to the area of rock surface exposed.
Thus, it is also related to mechanical weathering, which creates more exposed surface area by breaking the rock down into pieces, and those pieces into smaller pieces. Examination of the factors determining the degree of The aim of this diploma work is to do an examination of the factors determining the degree of gloss on paint films and also to study why it is not possible different Pigment-Volume-Concentration.
PVC is the volume fraction of pigment in the total volume of dry paint. Dry paint mainly. Semi-transparent vs solid deck stain Hi, I'm looking for a bit of advice on what to cover some wood decking with.
