The price of sealant is not the higher the better, there are many kinds of sealant, silicone sealant, polyurethane sealant, polysulfide sealant and so on. And each kind of sealant classification is different, it has different classification standards, can be classified according to the base material, can also be classified according to the purpose, can also be classified according to the performance. But the price of sealant is not the higher, the better. Only suitable sealant is good. It is good to choose the sealant needed according to its usage. Second, remind consumers to pay attention to whether the product capacity is enough when purchasing sealant. If the sealant capacity and the marked capacity are less, such sealant should be eliminated first, because such enterprises have problems and the product is not so good. If the capacity is too much, it is also a problem, which proves that the production process control of the purchased products is not strict, and the quality may not be very good.

Use of silicone sealant:

1. Use: single component silicone glass glue can be used immediately. It is easy to knock it out of the rubber bottle with the glue gun, and its surface can be trimmed with a spatula or wood chips.

2. Adhesion time: the curing process of silicone adhesive is developed from the surface to the inside. The surface drying time and curing time of silica gel with different characteristics are different, so the surface repair must be carried out before the surface drying of glass adhesive. If the color separation paper is used to cover a certain place, it must be taken away before the skin is formed after gluing.

3. Curing time: the curing time of glass adhesive increases with the increase of bonding thickness. For example, acid glass adhesive with a thickness of 12mm may take 3-4 days to solidify, but within about 24 hours, the outer layer of 3mm has been solidified. When bonded to glass, metal, or most wood, it has a peel strength of 20 pounds per inch after 72 hours at room temperature. If the place where glass glue is used is partially or completely closed, the curing time is determined by the tightness of the sealing. In an absolutely closed place, it is possible to remain uncured forever. If the temperature is increased, the glass glue will become soft. The gap between metal and metal bonding surface shall not exceed 25 mm. In all kinds of bonding occasions, including airtight conditions, the bonding effect of the equipment after bonding shall be comprehensively checked before use.

More reliable sealant products can have better waterproof effect, and the quality assurance will be greatly improved. Therefore, it is necessary to make a reasonable choice according to the actual situation, and the quality assurance will be greatly improved. Therefore, it is necessary to make a better choice according to the actual situation, and the reliability will be greatly improved, and the quality assurance achieved will be better 。
