The difference between 107 glue and 108 glue_Introduction of 107 glue and 108 glue

The construction glues we often talk about include 107 glue and 108 glue. Many people only know that 107 glue and 108 glue are two different construction glues, but they don’t know what are the differences between 107 glue and 108 glue. Next, let me explain

Let me tell you the difference between 107 glue and 108 glue.

1. Introduction to 107 glue 1. Introduction to 107 glue 107 glue, also known as "cultured water", is a colorless or slightly yellow viscous liquid.

It can be used alone as a binding glue and glue for books and periodicals. It can be used to paste wallpapers and plastic floors in building decoration. It is most commonly used to mix it with cement mortar to paste tiles.

Especially if the wall is uneven, it can be used to smooth it.

It can also be used complementary with 903. If the wall is uneven, 107 glue will have better results and the price will be lower.

The scientific name of 107 glue is polyvinyl formal adhesive, which is an adhesive formed from a solution or emulsion using water as the medium.

Because 107 adhesive has the characteristics of non-flammable, low price, and easy to use, it is widely used in construction projects and can be used as building adhesives and the base material of various interior and exterior wall coatings and floor coatings.

2. The main function of 107 glue 107 glue is an industrial glue used to adhere plastic floors or wallpapers during building construction.

107 glue can also be used as book binding glue.

As an adhesive using water as the medium, 107 glue is non-flammable, easy to use and low in price. It is the basic material for various interior wall coatings, exterior wall coatings and floor coatings in building construction.

107 glue has high value in construction and decoration projects. It can not only be used in adhesives, polymer cement slurries, etc., but also can improve some traditional finishing practices.

As a kind of construction glue, 107 glue plays a role in the preparation of paint putty and the mixing process of concrete. It can effectively improve the viscosity of concrete and play a bonding transition role between the base layer and the paint. 107 glue can replace animal and plant glues when used.

When the wallpaper is pasted, the bonding strength is high.

107 glue can maintain lasting elasticity within the temperature difference range of -60~220℃, and has excellent electrical properties, chemical stability, water resistance, weather resistance, etc.

These unique properties make 107 glue widely used in joint filling construction, electronic product insulation, rubber and plastic product molding, etc.

107 glue is also the base material of room temperature vulcanized silicone rubber.

3. The main hazards of 107 glue 107 glue is a water-soluble adhesive made by neutralizing after the condensation reaction of polyvinyl alcohol aqueous solution and formaldehyde solution under the catalysis of hydrochloric acid. It contains free formaldehyde, which basically exceeds the standard and seriously pollutes the environment.

Very harmful to health.

Solvent-based pressure-sensitive adhesive Rubber-based or acrylic solvent-based pressure-sensitive adhesive uses a large amount of toluene and other volatile organic solvents. The solvent evaporates and the smell is overflowing, which not only pollutes the surrounding environment, but also damages human health.

4.Use of 107 glue 1. Making interior walls: Base: 107 glue is directly mixed with 40% white cement and 60% talcum powder, and the appropriate amount of glue is used.

Surface: 107 glue is mixed directly with talcum powder.

(It is best to add a mixture of cooked glue powder and water) 2. For exterior walls: 107 glue is directly mixed with 70% white cement and 30% talcum powder, and the appropriate amount of glue is used.

2. Introduction to 108 glue 1. Introduction to 108 glue 108 glue, also known as "polyvinyl formal glue", is a polymer bonding solution produced by the condensation reaction of polyvinyl alcohol and formaldehyde in an acidic medium.

It is a translucent or transparent aqueous solution.

It is odorless, tasteless, non-toxic, has good bonding properties, and the bonding strength can reach 0.9MPa.

It can be stored for a long time at room temperature, but it is prone to gelation at low temperatures, and may become moldy and dirty if left under high temperature conditions for a long time.

In addition to being used for wallpaper and wall coverings, polyvinyl formal glue can also be used as a configuration material for indoor and outdoor wall and floor coatings.

Combined with gypsum powder or talcum powder to form a paste, it can be used for base treatment of indoor and outdoor walls. Adding 108 glue to ordinary cement mortar can increase the bonding force between the mortar and the base layer.

2. The construction temperature of 108 glue should be above 5℃.

The construction and maintenance temperature is above 0℃.

108 glue is stored and transported in a ventilated, light-proof and dry place with a room temperature not lower than 5°C. The shelf life is 12 months.

The product is non-toxic and non-flammable, and storage and transportation can be handled in accordance with the "Non-Dangerous Goods Regulations".
