Sealants are polymers with an extremely tight molecular structure that doesn't allow for penetration. They have fast-drying epoxies, which create a smooth finish. Adhesives have a complicated structure designed to grab and bond at a cellular level.
Stix-All Adhesive
Stixall is a very strong adhesive that can be used to bond the mirror to glass and mirror glass to tile mirror glass to stone mirror glass to steel mirror glass, and wood lacquered glass onto glass lacquered glass and tile, lacquered glass to concrete lacquered glass to stone lacquered glass to metal, lacquered glasses to wood from metal to plastic, to plastic, stone fiberglass, concrete. Alstone Stixall is especially used to paste mirrors as well as lacquered glass. It is used for lighting and bathroom fittings, too.
Sealants
Sealant is a chemical that blocks the flow of fluids across joints, surfaces, or cracks in the material, a kind that is a mechanical seal. In construction, the sealant is often referred to as caulking and serves to block dust and heat, and sound transmission. Sealants could be strong or weak, rigid or flexible, and long-term or short-term. Sealants aren't adhesives. However, some have adhesive properties and are referred to as adhesive sealants or structural sealants.
Stix-All Adhesives VS Sealants
- Sealants are made to seal the gaps between surfaces and stop things like water, dust, or dirt from getting in. The purpose of adhesives is to stick two surfaces to each other, not separate.
- Sealants have lower strength and high elongation/flexibility and are not used to bond materials together, while adhesives are meant to stick two things together by adhesion.
- They don't possess the power of adhesion required for long-term adhesion, and adhesives won't get properly dry when placed on an external surface.
- Sealants possess a paste-like consistency, which permits filling gaps between substrates. They also have minimal shrinkage after application. Adhesives are liquid that solidifies after application, and they can then be utilized to bond materials. Adhesive provides an extra-rigid and durable appearance and feel, unlike sealants, which have less strength and are considerably more malleable.
- The adhesive Stix-All is a VOC free product, whereas sealants can be prone to produce VOC
- Stix All adhesive can be used over damp surfaces as well as underwater applications, whereas sealants don't
- Stix All adhesive is a paintable rubber, while sealants aren't.
- Stix-All adhesive is designed to bond glass or wood, metal plastic, ceramic, stone, etc., after 15 minutes from application, while sealants are not made to glue any material.
- Stix-All is a high modulus adhesive with a load-bearing capacity of up to 150kg/m3.
What are the various uses of adhesives and sealants?
In deciding which sealant or adhesive to select, engineers must consider many questions to figure out how it can be utilized for their purposes.
The first question is what material the object bonding is made of and what kind of conditions does it require to be able to endure? First, ask if it is a structural or non-structural bond? Do the bonds have to be able to support loads on an object? In this instance, it is necessary to use a structural adhesive. It is also connected to another thing that is performing the load-bearing for the job, like welding or rivets? In this case, either a non-structural adhesive or sealant is required to accomplish the task.
The next step is to decide if you want an adhesive or sealant, which one, what is the material of your substrate, and what are the environmental and thermal conditions that the bond will have to endure? Certain adhesives are superior in forming bonds to specific substrate materials, like ceramic, glass, or certain metals and plastics. The environmental conditions could include the different types of stress such as that are compressive, tensile or continuous or intermittent, the operating temperature load, and the chemical exposure in which a bond will be utilized. Other more specific conditions could be the need for thermal or acoustic insulation. Optical properties, electrical properties, or UV stability serve as a fire-proofing material or give an appearance on a particular surface.
Other factors to consider are bonding substrates with various mechanical qualities, for example, different elongations in stress or different values of the coefficient of thermal expansion. In the case of sealants, it will need enough elongation and flexibility to meet the demands of the substrate material. The ability to shrink down after application might also be required.
Conclusion
Additional requirements for adhesives might include different kinds of surface preparation needed as well as whether the bond gap should be thick or thin and whether the component is vertically or horizontally aligned as well as the required life span and the application equipment, as well as whether either thermal as well as UV (Ultra Violet) treatment is required. All of these and other factors may determine how easily the adhesives are included in the production line.
Once they have made these choices, engineers can then select the right chemistries.
