What Are the Different Types of Concrete Adhesive?

A type of adhesive used on stressed parts. Generally, the stress that the cement joint can withstand is equivalent to the strength of the adherend itself. The adhesive itself has excellent heat resistance, resistance to media, resistance to atmospheric aging, vibration fatigue, low creep, and high durability.

English name: structure adhesive

Description: A type of

Structural adhesives are mostly used for the bonding of engineering structural parts, also known as

Non-structural adhesives have low strength and poor durability. They can only be used for bonding of structural parts due to ordinary, temporary bonding, sealing and fixing.

Structural adhesives are widely used in engineering, mainly for the reinforcement, anchoring, bonding, repairing of components; such as sticky steel, carbon fiber, planting bars, crack reinforcement, sealing, hole repair, road nailing, surface protection, concrete Bonding, etc.

Different types of structural adhesives are used in different ways, but are generally the same.

1. Surface treatment: roughen the parts to be repaired or to be bonded, and then clean them with a cleaning agent.

2. Preparation: Mix the two components A and B according to the mass ratio A: B = 4: 1 or volume ratio 3: 1, and use them up within the specified operating time limit.

3. Coating: Apply the adjusted glue evenly to the surface of the object to be adhered.

4. Curing: curing at 20 25 for 24 hours or curing at 20 25 for 2 hours + 80 for 2 hours can be put into use. If the temperature is low, heating or extending the curing time should be used to promote curing. ^[2]

1. Two-component, 250g / set, 16 sets / carton.

2. Store in a cool and dry place in a sealed container with a shelf life of 2 years.

Is a substance with good adhesion properties. Through the adhesion and cohesion from the surface adhesion to play the role of connecting objects.

Organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts (or materials) together with sufficient strength after curing, collectively referred to as adhesives or Adhesives, adhesives, and conventionally referred to as glue.

Divided into natural polymer compounds (starch, animal skin rubber, bone glue, natural rubber, etc.), synthetic polymer compounds (epoxy resin, phenolic resin, urea resin, polyurethane and other thermosetting resins, polyvinyl acetal, perchloroethylene resin, etc. Thermoplastic resin, and synthetic rubber (such as neoprene, nitrile rubber), or inorganic compounds (silicate, phosphate, etc.) According to the requirements of use, curing agents, accelerators, reinforcing agents, ene release agents, fillers, etc. are often incorporated into the adhesive. Classified according to use, it can also separate warm glue, sealant, structural glue and so on. There are room temperature curing adhesives and pressure-sensitive adhesives according to the use process. Adhesive can be used to connect dissimilar materials and sheet materials, and the stress distribution at the joint is even. In container manufacturing and repair, epoxy resin, neoprene, and sealant are commonly used.

In recent years, organic adhesives have been used more and more widely, and the bonding technology has also matured, and has become one of the three major connection technologies of bonding, welding and mechanical connection. ^[3]
