The effect of thinner on paint gloss and the common phenomenon in site construction

Paint itself has a high-gloss, bright, matte, flat, matte, etc. , these are paint production after determining its gloss range, this paper only talk about the thinner on the luster effect, can not change the paint itself gloss.
believe that thinners are merely diluted paints and have no effect on the performance of their paint film. Construction is more casual use, there is any thinner around the use of which, regardless of the primer thinner or paint thinner mixed with

. There are individual attention, primer thinner and paint separate use, but do not distinguish between manufacturers or do not distinguish between fast and slow dry thinner.
paper singles out the effect of thinner on paint gloss, but also in the field construction of several phenomena.
01 thinners are fast-drying, standard, slow-drying, and the drying speed at the right time can make the paint gloss higher
Many manufacturers will be fast and slow dry thinner packaging logo. This provides great adjustment space for on-site construction.
02 solubility of the material will appropriately increase the gloss of the paint
the role of the thinner is to dilute the paint, reduce viscosity, so that the paint to achieve the construction needs of viscosity and the best construction results. After construction, the thinners will all evaporate into the atmosphere, which is difficult to recycle. This is also the paint caused environmental pollution, and is the main reason for everyone to replace with water-like paint. So the lower the price, the better.
the dilution process requires two points for the thinner:
A, diluent solubility can not be too weak, if too weak will cause paint flocculation into clumps, can not dilute the paint. Needless to say, many people have experienced such incidents. The thinner is added to the paint, the paint is separated from the thin material, the upper layer is clarified by the thin material, and the paint below shrinks into a ball. And no matter how you stir, the paint is like a bubblegum, sticky, and never blends with the thinner.
B, diluent solubility can not be too strong. Too strong a thinner will cause the pigment in the paint to flocculate and the pigment to be removed from the paint. This type of phenomenon is more hidden and, in many cases, not. The solubility of the diluent may also dissolve the underlying paint, causing bites and other phenomena.
03 how much of the thinner on the paint gloss effect
thinner add too much will reduce gloss, mainly due to the addition of too much diluent, paint solid content decreased, dry film thinning, paint is not full, resulting in low gloss.
04 thinner selection can also cause the following paint film ills:
loss of light: paint film before drying luster full, lack of gloss after drying or later paint film gloss gradually disappear.
: the surface of the paint film uneven, similar to the appearance of orange peel, grapefruit skin.
clouds/spots (small spots of silver paint): The color of the silver paint changes to form a patch or dark or light color spot, often with stripes of different colors along the direction of the paint.
pinholes (holes): coating after coating due to the sharp volatility of the thinner, so that the lacquer liquid can not be replenished, resulting in pinhole-like small holes or like leather pores phenomenon.
