Can different types of filling glue in the reinforcement material be used interchangeably?

Apr. 02, 2019


Common filling glue is generally used for bonding, sealing, filling and coating protection of electronic components. In the building reinforcement industry, the filling glue also has a wide range of applications. According to the material types, the filling glue is mainly divided into three types, namely epoxy resin filling glue, silicone resin filling glue, and polyurethane filling glue. But do you know what role and characteristics of these filling glues are? Can it be replaced by each other? Next, let’s uncover the mystery of the secret.

Epoxy resin filling glue: Take Mankate filling glue as an example, the filling glue is a two-component epoxy resin filling glue, which has the following characteristics:

1. Good performance, long application period, suitable for a large number of automatic production line operations. 

2. Low viscosity, strong impregnation, can be filled between the seam and the concrete gap. 

3. The curing exothermic peak is low and the curing shrinkage is small.

4. The cured product has excellent electrical and mechanical properties, good heat resistance, good adhesion to various materials, and low water absorption and linear expansion coefficient.

 

Scope of application (take Nanjing Mankate advanced filling glue as an example).

1. Crack repair in concrete works. 

2, Concrete internal defects (cellular, loose) injection reinforcement repair.

3. Filling of empty walls and floor tiles.

Silicone Filling Glue: Silicone Filling Glue is a good fluidity addition cure silicone rubber resin.

1. The rubber is semi-solidified after solidification, and has good adhesion and sealing performance to many sheets, and has excellent resistance to cold and heat exchange. 

2. After mixing the two components, it is not easy to gel faster, so it has a longer operable time. Once heated, it will solidify quickly, and the curing time can be controlled freely.

3. No by-products are produced during the curing process, and there is no shrinkage. 

4, It has excellent electrical insulation properties and high temperature resistance (-50 ° C ~ 200 ° C). The glue is mainly used in industrial products.

Polyurethane sealing glue: Polyurethane filling glue, also known as PU filling glue, usually consists of polyols such as polyacetate, polyether and polydiene, and diisocyanate, with glycol or diamine as chain extender. It is aggregated after a gradual polymerization.

 

Features: Polyurethane filling material has low hardness, moderate strength, good elasticity, water resistance, mold resistance, shock resistance, transparency, excellent electrical insulation and flame retardancy, no corrosion to electrical components and some metals such as steel, aluminum, copper, tin. And for rubber, plastic, wood and other materials, it has good adhesion. It is mainly used in industry.

 

In summary, it can be seen that different types of filling glue have different characteristics and application scopes. Remember to use them indiscriminately. Once errors occur, it will not only waste manpower and material resources, but also greatly affect the overall reinforcement project. Therefore, in the reinforcement projects, always consult a professional before use to ensure that all reinforcement materials meet the construction requirements. Mankate insists on providing you with excellent quality service. Your choice is our pride!
