Precautions for the use of sealant

The sealant manufacturer tells everyone to pay attention to waterproofing when using it. For example, many sealants are used in bathrooms, and toilets are inherently damp and are prone to mould. Therefore, the sealant must be a real anti-mould agent, and it is better to use a zero-level anti-mould.

The general sealant must be seen in the bottle. At present, the 7 yuan to 20 yuan sealant on the market has an average anti-mould effect, or some people no longer prevent mould, including the pipes in the kitchen and the mould-proof spots that have changed over the past year. Over time, the adhesive becomes thinner, more mould, unsightly, leaky, and other poor quality sealants have no such function at all, so you must understand when buying.

Silicone structural sealant and silicone weather-resistant sealant should be used within the validity period, from the day of admission to the end of curtain construction. Light-coloured, coloured, and transparent silicone structural sealants have poor UV resistance and are only suitable for indoor engineering. Generally, black is used outdoors. The environment for storing the adhesive must meet the temperature and humidity requirements.

How to store sealant?

1. Organic silicon sealant for high-performance building structure with the national chemical at room temperature. It can be simply squeezed for construction, reacts with moisture in the air, and solidifies into an elastomer without cold resistance, heat resistance, and corrosion.

2. Ozone resistance, UV resistance, etc., with outstanding weather resistance, can give people a long life.

3. It has good cohesiveness and does not need to be primed under normal conditions. After curing, it can produce good adhesion on the surface of many building materials, such as glass, aluminium, steel, stone and so on.

4. Good compatibility with silicone structural rubber, weather-resistant rubber and neutral rubber.

The opened silicone structural sealant needs to clean the nozzle when re-storing, seal the new chip, and keep it sealed. It should be stored properly according to the preservation method of the silicone structural sealant, but it must be used as soon as possible. Sealant-generally stored in a shading ventilated room; the temperature requirements are not great, the storage period of the silicone structure sealant is related to the temperature, if the room temperature is about 20 degrees, the silicone structure sealant-generally can be stored Three years.
