Acrylic and silicone sealant - this is a different means of both composition and application. They have the same purpose. Means to seal seams and cracks, fill cavities and seal joints during construction or repair work.
Features of silicone sealant
In the basis of a good silicone sealant - silicon polymers, enhancers, plasticizers, vulcanizers, antiseptics. The range of means is large:
acidic, which are based on acetic acid;
neutral, based on alcohol and ketoxime;
one-component, fully ready to work, forming a layer from 2 to 12 mm;
two-component, suitable for large volumes, but the components must be mixed before work;
silicone adhesive sealants.
Silicone penetrates well into even the smallest gaps, fills gaps and joints, glues the parts. The solidified sealant withstands deformation and is not destroyed by mechanical impact, at the same time retains elasticity and strength. Waterproof material connects with glass, wood, ceramics, metal, concrete, but is not suitable for non-ferrous metals. Silicone sealant can withstand temperatures from 50 ° to plus 200 ° C, is not afraid of direct sunlight.
The product is used for waterproofing in households and production both inside and outside buildings. Silicone is suitable for use in rooms with high humidity, as well as for repair of facades, windows, doors.
Features of acrylic sealant
In the basis of acrylic sealant - aqueous dispersion of polymethylmethacrylate, fillers, thickeners, plasticizers, ammonia solution, biocidal, that is, antifungal additives. Acrylic product is used for interior work: sealing seams and cracks in walls, ceilings, windows and doors.
Sealant polymerizes within 24 hours when the chemical substances of the composition interact with air. The result is a hard elastic mass that fills small cracks and roughness well. It can be used on almost all surfaces made of wood, metal, plastic, concrete, porous bricks and stones. The composition is heat-resistant and works in the range from -40 °C to +80 °C, but it should not be frozen if stored, the sealant will lose its properties.
What are the differences between silicone and acrylic sealants
The differences between sealants are in their basic properties, scope of application and method of application.
Silicone is packed in tubes with a cone nozzle, with which it is applied to cracks and joints. Acrylic sealant is produced both in tubes and in containers. It can be applied with a special device - applicator, or with a spatula. Here you can see more - https://belife.ua/ua/category-germetiki-i-silikoni/
Acrylic composition after drying can be painted, so the seam is easy to disguise under the surface, in the future to restore. On top of silicone paint can not be applied. If the sealant at the joint or in the place of connection is damaged, then you will have to change it completely.
Silicone sealant is resistant to water and moisture, acrylic over time in harsh conditions is destroyed, loses properties.
Acrylic sealant allows steam to pass through, silicone forms a completely airtight joint. Such properties should be taken into account when choosing for different conditions of application.
For porous, rough and uneven surfaces, acrylic sealant is better suited. The composition fills small cracks well. Silicone lays down better on tiles, ceramics, glass, plastic.
Sealants differ in color. Silicone come in transparent, white, black, gray, red. Acrylic - almost any color.
An important difference between silicone and sealant is the different service life. Silicone will last more than 20 years, acrylic has the property to dry out and crack over time. In addition, treated seams from constant moisture can be covered with mold. In such cases, antifungal compositions are used to treat joints in bathrooms, showers, saunas and pipes.
