Best sealant|The difference and application of sealant and glass glue

Glass glue is a material for bonding and sealing various glasses with other substrates. There are two main categories: silicone rubber and polyurethane rubber (PU). Silicone glue is divided into acid glue and neutral glue, structural glue and so on. Polyurethane glue is divided into bonding glue and sealant.
Specific application of glass glue
1. Suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging. 2. Sealing the joints between metal, glass, aluminum, ceramic tiles, plexiglass, and coated glass.
3. The joint sealing of the surface of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. In most cases, no primer is needed.
4. It has superior weather resistance such as ozone resistance and ultraviolet resistance, giving it a long service life.

Sealant introduction
Sealant refers to a sealing material that deforms with the shape of the sealing surface, does not flow easily, and has a certain degree of adhesion. Usually dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as the base material, and then inert fillers are added, and plasticizers, solvents, curing agents, and accelerators are added. And so on. The sealant is distinguished from the performance. The single-finger function is to seal. Weather-resistant adhesives, silicone structural adhesives and polyurethane adhesives all have sealing functions, but they have other very important functions, such as high bonding strength and good weather resistance.
Specific application of sealant
1. Classified by purpose, it can be divided into construction sealants, automotive sealants, insulating sealants, packaging sealants, mining sealants, etc.
2. According to the performance classification after construction, it can be divided into two types: curing type sealant and semi-curing type sealant. Among them, curing type sealant can be divided into rigid and flexible. The solid sealant formed after vulcanization or solidification is rare. It is elastic and cannot be bent, usually the seam cannot be moved; the flexible sealant has elasticity and softness after vulcanization. Non-curing sealant is a soft coagulant sealant that remains non-drying after construction and the tackifier continuously migrates to the surface state.
