Many people do not know what sealant is in decoration, and often confuse sealant and glass glue. In fact, they are two different things, and their uses in our decoration are also different. What is the difference between sealant and glass sealant? What are the classifications of sealant and glass sealant? Today we will talk about sealant and glass glue.
Let's take a look at the differences between sealant and glass sealant together!
What is sealant
Sealing glue is a sealing material that deforms according to the shape of the sealing surface, is not easy to move, and has a certain degree of adhesion. It is an adhesive used to fill open spaces in structures and provide a sealing effect. It has functions such as leakage prevention, waterproofing, anti oscillation, sound insulation, and heat insulation.
Generally, dry or non dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as base materials; Collaborate with inert fillers such as talc, clay, carbon black, titanium dioxide, and asbestos, and then add plasticizers, solvents, curing agents, accelerators, etc. to make it.
Classification of sealant
Sealing glue can be divided into three categories: elastic sealing glue, liquid sealing gasket, and sealing putty.
According to chemical composition classification, it can be divided into rubber type, resin type, oil-based type, and natural polymer sealant. This classification method can infer the sealing performance and adaptability to various media of polymer materials based on their characteristics.
Rubber type: This type of sealant is based on rubber as the base material. Commonly used rubbers include polysulfide rubber, silicone rubber, polyurethane rubber, chloroprene rubber, and butyl rubber.
Resin type: This type of sealant is based on resin. Common resins include epoxy resin, unsaturated polyester resin, phenolic resin, polyacrylic acid resin, polyvinyl chloride resin, etc.
Oil based type: This type of sealant uses oil as the base material. Commonly used oils include various vegetable oils such as sesame oil, castor oil, tung oil, animal oil, and fish oil.
According to the application scenario, it can be classified into high temperature resistant, cold resistant, pressure resistant, etc.
According to the shape of the film, it can be classified into dry adhesive type, dry peelable type, non dry adhesive type, and semi dry viscoelastic type, which is also a commonly used classification method for sealants in China.
Classified by purpose, it can be divided into construction sealant, automotive sealant, insulation sealant, packaging sealant, mining sealant, and other types.
According to the functional classification after construction, it can be divided into two types: cured sealant and semi cured sealant. Among them, cured sealant can be divided into rigid and flexible. Rigid sealant is a solid formed by vulcanization or coagulation, which rarely has elasticity, cannot bend, and generally cannot move the joint; Flexible sealant has elasticity and flexibility after vulcanization. Non curing sealant is a soft and cohesive sealant that persists in non drying after application, with the adhesive constantly moving to the surface.
What is glass glue
Glass glue is a material used to bond and seal various types of glass with other substrates.
Classification of Glass Adhesive
Mainly divided into two categories: silicone adhesive and polyurethane adhesive (PU). Silicone sealant&dash& mdash; It is commonly referred to as glass sealant, which is divided into acidic and neutral types (neutral sealant is further divided into stone sealant, anti mold sealant, fireproof sealant, pipeline sealant, etc.)
The difference between sealant and glass adhesive
Glass glue is a general term, and both silicone glue and polyurethane glue can be commonly referred to as glass glue. Sealing glue is functionally different from others, and its primary function is to seal.
The primary purpose of sealant is to seal the seams, and glass sealant is generally used for sealing, especially for waterproofing in kitchens and bathrooms. After using glass glue, windows should be opened for ventilation to prevent air inhalation in the short term.
