Glass glue, as we all know, is a common adhesive. It can bond and seal all kinds of glass with other materials, so this kind of material is also necessary for us to use in decoration. Although many friends may not know much about glass glue, we know its function is very great in decoration. So if we want to buy a glass glue, what kinds of glass glue are there? What brands are worth buying? Let's introduce it to you.
brief introduction of glass glue
glass glue is a kind of adhesive commonly used in families, and its main components are sodium silicate (Na2O·mSiO2), acetic acid and organic silicone. Sodium silicate is soluble in water and sticky. It is also called sodium silicate in the south and sodium silicate in the north. Glass glue is a material for bonding and sealing various glasses with other substrates. Mainly divided into two categories: silicone adhesive and polyurethane adhesive (PU). Silicone sealant-that is, what we usually call glass sealant, can be divided into two types: acid sealant and neutral sealant (neutral sealant can be divided into stone sealant, mildew sealant, fire sealant and pipeline sealant, etc.).
types of glass glue
1. acidic glass glue: the glass glue with the lowest average price is also the easiest to buy. Its remarkable feature is that it has obvious pungent smell after opening, and its curing time is short. Usually, the surface can be completely dried in about 2 hours and completely cured after 24 hours. Its viscosity is the strongest among silicone adhesives (glass adhesives). Acidic glass glue is corrosive and will corrode the coating behind the mirror, so it can't be used to stick the mirror. Because of its good sealing, it is usually used for edge sealing and leakage prevention. Scope of use: sealing doors and windows, sealing around sinks and toilets, and sticking glass materials with other building materials.
second, neutral glass glue: the same brand, the same series of glass glue, neutral than acidic generally 3-about 4 yuan. Neutral glass glue overcomes the shortcomings of acidic glue which is easy to corrode materials, and has a wider application range. Neutral glue has no pungent smell, which makes people feel more comfortable when gluing. The curing time of neutral glass glue is a little longer, generally, the surface is dried for 3-4 hours and completely cured after 48 hours. Scope of use: it can be used to paste wall decorations, mirrors and various materials, etc., and can also be used to quickly repair a single fallen tile.
3. Nail-free glue: Nail-free glue can be regarded as a reinforced version of neutral glass glue. Because of different manufacturing processes, it combines the advantages of acid glass glue and neutral glass glue, and has high adhesion without causing corrosion to building materials, so it can be used as an adhesive for most materials. The price of nail-free glue is 2-3 times that of neutral glass glue, and the curing time is basically the same as that of neutral glue. Because of the high cost, general decoration companies and processing plants will not choose this kind of glue. Nail-free adhesive is more suitable for pasting large-area and heavy-weight items. Most of the items that need to be pasted at home are light-weight items, and the advantages of nail-free adhesive cannot be clearly reflected. In addition, nail-free adhesive is not good in sealing and waterproof, so it can't be used as kitchen and bathroom sealant. Scope of use: Sticking heavy objects to vertical surfaces.
What are the related issues about the types and brands of glass glue? We should have some understanding of this problem. We know that glass glue is a material that we often use in decoration, but different types of glass glue are suitable for different materials, so we should pay attention to these problems when choosing glass glue. Don't choose the wrong glass glue. We should choose the type of glass glue according to the materials we need.
