Universal silicone sealants.

As you know, to get rid of noise, dust, drafts, simply put a plastic window. So as not to overshadow the potential comfort, window frames should be well sealed. You will say, and what better to do? Answer. Better way than the sealant, you will not find our time. That's about it today and we'll talk. Efficient, reliable, durable - all these qualities are inherent in silicone sealant. Compared to other sealants, these versatile materials - very flexible in its structure, can withstand sudden temperature changes. And all this because of what their basis is silicone (silicone material). In addition, such sealant is not afraid to direct sunlight. In its structure, one-component silicone sealants - are always ready for use, not only very practical (they do not need to mixing with hardener), do not spread after application. Viewed sealant retains its working qualities over 20 years. Depending on the type used in the manufacture of solvent, silicone sealants can be divided into the following types: a) acid b) neutral c) alkaline. I have to say - Alkaline sealants are used only in certain cases, so they are on the shelves of our stores you will not find. However, these same stores, you can easily buy acid variant. It costs a lot less neutral silicone, but is able to hold well on wood, glass and ceramics. To distinguish this from other sealant, is only to look at the packaging. Marking acid variants should contain the letter "A" (acid - from the English word «acid»). It is worth paying attention, because the chemical in question can react with metals that are prone to oxidation. Acid sealant may also damage some building stones (granite, limestone, marble) and a mixture containing alkali impurities (concrete, etc.). If the acid variant is not able to cope with this task, then you come to the aid silicone version with a neutral impact on the materials. Their marks contain the letter «N» (neutral - from the English word «neutral»). Verify the authenticity of the sealant can be sniffed open tube - if the smell of alcohol - then you have in the hands of a neutral variant. Apply the silicone can be in areas where acid composition is contraindicated - concrete, marble, metal, prone to corrosion. Nonetheless, silicone sealants have one drawback - they are forbidden to work with materials such as polyacrylate and polycarbonate. Silicone composition can not tightly sealed, because detrimental effect on them. These sealants inherent in one more feature - they can not be painted. Fortunately, the manufacturers produce them in large color range. Therefore, the time of purchase, you simply have to select the color that will not break your color scheme.
