Perimeter sealing
Introduction
A sealant or sealant is a viscous material that changes to a solid state once applied and is used to prevent the penetration of air, gas, noise, dust, fire, smoke or liquids from one location to another through the sealed barrier.
Sealants help in the maintenance and care of properties. The correct choice allows you to obtain greater benefits from the product, such as: impermeability, elasticity, performance, durability, aesthetic finishes, etc.
Silicone sealants
Sealants that use silicone as their main component are developed for: structural sealing on facades, structures, curtain walls, etc.; as a secondary seal on double or insulated glass; thermal expansion joints in concrete roads; butt joints and perimeter seals; in the union between different materials (concrete and glass, concrete and metal, concrete with glass, glass with metal, glass with glass, etc.) and, especially, they have excellent adhesion on polycarbonate and PVC.
Some of the characteristics that make them stand out compared to other seals are: they prevent the formation of fungi, which makes them of special interest in sealing kitchen joints "Kitchen (room)") and bathrooms; Being an inorganic material, they last longer since they resist UV rays; maintain their properties over time (elasticity "Elasticity (mechanics of solids)"), movement capacity, adhesion strength, etc.); and are more elastic than most other sealants.
Polyurethane sealants
They are made with polyurethane and specially designed to seal joints and cracks with strong and moderate movements in walls, gates, cisterns, door frames and between prefabricated elements.
Among the characteristics that stand out in this type of sealants are: that they offer excellent adhesion on all types of materials such as: concrete, wood, asbestos, cement, steel, aluminum, glass, among others; they can be painted; They last longer and resist the elements; and they are elastic in some of their varieties.
