What are the characteristics of silicones

This material is very elastic and has a strong adhesive power on smooth surfaces such as ceramic, glass and metals. It is not recommended for salty or porous surfaces such as concrete, concrete and bricks. Among the existing alternatives, there are 3 varieties :

– Silicone with Fungicide : Used in areas such as bathrooms and kitchens. It is ideal for repelling fungus and mildew.

– Neutral silicone : It is 100% pure, to be used directly on polycarbonates and fiberglass plates, allowing them not to stain, it does not damage aluminum or mirrors.

– Multi-purpose silicone : It has a solar filter to resist weathering and UV rays. If you work in the industrial sector and have specific silicone needs, you can seek advice and purchase from Elkem, a professional supplier. You can also refer to this article they wrote about PSA.

What are the characteristics of sealants?

A sealant is a sticky substance that solidifies after adhering to some material. It acts as a barrier, widely used to cover and close cracks so that water, air, noise and smoke cannot penetrate from one area to another. There are different types depending on the components and uses :

– Acrylic Sealant : When there is an open space between the wall and the window or door frame, acrylic is an excellent sealing option. It is easily applied with a caulking gun to seal cracks in plaster and joints in building materials.

– Polyurethane Sealant : High-performance adhesive with strong initial adhesion. Forms permanent elastic bonds, is UV resistant and waterproof. Can be painted and sanded.

– Multipurpose sealer : Adhesive for all types of materials and environments. Highly resistant to weathering and external agents. Paintable and vibration absorbing, it acts as a thermal insulator.

What are the characteristics of adhesives?

Adhesives are products capable of joining the surface of two bodies, of identical or different materials.

– Contact adhesive : Used to glue wall coverings or join objects, it dries faster without leaving stains.

– Epoxy adhesive : This is a two-component adhesive. To use it, you must mix the two before it can work as a glue. It is used for bonding concrete, stone, mortar, steel, iron, fiber cement, wood, and also for bonding dry concrete with mortar.

– Vinyl Adhesive : For bonding vinyl flooring to surfaces such as concrete and wood, among others. Solvent-free and odorless.

– Adhesive Assembly : Used to bond moldings, baseboards, wood panels, polystyrene insulation boards, among other materials, without the need for screws. It sets immediately and fills to improve adhesion.

– Carpet Adhesive : For bonding all types of textiles such as floor coverings, felts and carpets to the floor.
