FAQs on Best Concrete Adhesive for 2020

What are the types of structural adhesive?

There are many types of adhesive such as epoxy, acrylic, anaerobic acrylic, and many more. The epoxy adhesive is said to have appropriate shear or tension and can act as a good mechanism for resistance. It is also resistant to high temperature and some harmful chemical reactions and for this type of adhesive, the reversibility of glue is possible. The acrylic adhesive is good in spellings and the gas and also has enough amount of shear or tension to act as the mechanism for resistance. The anaerobic acrylic adhesive can be used as the thermosetting and single component of paste.

When is the Epoxy adhesive used?

In case, if you need the high mechanical strength then you can opt for the adhesive which has the quality of the epoxy one which is good in the aspect of shear or peeling. This type of adhesive is available in the market in the format of a single or two-component of paste. To polymerization, the single component-based of the epoxy adhesive you require is the temperature between only 100 to 200 degrees Celsius and can easily be done in the oven within half an hour. The epoxy adhesive veg single component-based can be the best alternative for welding.

When is the silicone adhesive used?

When you need the high resistance to apply on the concrete material then you require the silicone adhesive. The high resistance silicone adhesive offers you with good dynamic efforts and is resistant to UV rays, very high temperature, and also to the solvents and these features help it in becoming the good sealing. For the good amount of moisture content, you can refer to the silicone adhesive with single component-based and if the humidity is already very low then the adhesive with two-component of paste is recommended. The mechanical strength of this type of adhesive is not very much great as compared to the epoxy adhesive.

When is the acrylic adhesive used?

If you are planning to bond the metals with the wood, plastic, and the glass then the type of adhesive which is suitable for this purpose is the acrylic one.
