What is the difference between sealant and general-purpose sealant?

Both sealant and general-purpose sealant have bonding function. Although both are glues, they are very different. They are mainly reflected in the following aspects. Let’s take a look!

Product structure is different

Sealant: often based on dry or non-dry viscous materials such as asphalt, natural resin/rubber or synthetic resin/rubber, combined with inert materials such as carbon black, titanium dioxide and talc, and then adding curing agent, Accelerators, etc.

General-purpose sealant: the main components are water-soluble sodium silicate and acetic acid and organic silicone.

Different application areas

Sealant: The first purpose of sealant is bonding and sealing, and it is often used in the sealing of construction, transportation, electronic instruments and parts.

General-purpose sealant: mainly used for bonding glass, bonding various glass with other materials, it is the core of building materials, mainly used for waterproof and moisture-proof exterior wall, indoor bathroom anti-mildew, flame retardant, high and low temperature resistance, etc. multiple uses. It is also widely used in home decoration, such as: sanitary ware, toilets, cosmetic mirrors in the bathroom, and the back of the wooden line.

Product works differently

Sealant: easy to flow, seal, and have certain adhesiveness. It is used to fill the configuration gap to achieve a sealing effect. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation, and has certain anti-aging properties. It has high bonding strength and good weather resistance.

General-purpose sealant: It dries quickly, has a heavy sour taste, is not environmentally friendly, and has poor anti-aging properties, but it will not corrode objects and has strong adhesion.

Obviously, the difference between sealant and glass glue is still very big. Only by understanding the characteristics and uses of sealant and glass can we better choose the appropriate sealant or general-purpose sealant.
