Today, quite often, construction work is carried out using polyurethane foams. They became available at a cost and to the ordinary consumer. Their application can be carried out in different ways, and one cylinder has a rather impressive yield of material. However, the private consumer may be confronted with the difficulty of choosing. Manufacturers offer for sale mounting foams for professional and domestic purposes.
Having familiarized yourself with the assortment of the modern construction market of polyurethane foams, you can find the Soudal products. It is a material that was developed by a European manufacturer, and therefore compares favorably with its counterparts in increased adhesion to different types of surfaces. As an exception, we can distinguish:
- polyethylene;
- teflon;
- silicone.
If you also decided to purchase this composition, then you should familiarize yourself with its technical characteristics and find out the opinions of consumers.
Technical characteristics of Sudal polyurethane foam
Sudal foam is a material based on polyurethane. Hardening occurs in a humid environment. This composition has the form of a stable thixotropic foam, the cellular structure of which is characterized by the presence of 80% of isolated pores. The density of the material is 25 kg / m 3 . This is true for solid mixtures. After 25 minutes, the material acquires a dry-to-touch structure, which is true at 20 ° C air and 65% relative humidity.
Foam "Sudal" after 8 minutes forms a surface film, which is true under the same conditions that were mentioned above. For a 3 cm gap, the cure speed is 60 minutes. About 70 liters should come out of one cylinder, which will depend on relative humidity and air temperature. The Sudal polyurethane foam is all-weather, the technical characteristics of which also suggest heat resistance, can be used in the range from -40 to +90 ° C. This is true for a completely solid composition.
The application temperature is in the range of +5 to +35 ° C. Specialists are sometimes also interested in the isolation factor, it is 35 mW / m · K. Fire resistance corresponds to level B3, while sound insulation is 58 dB. Shear strength is 17 N / cm², but the compressive strength is 3 N / cm². Moisture absorption is equivalent to 1%. Bending resistance is 7 N / cm².
Key Operational Features
Consumers like that the Sudal foam described in the article is offered for sale in a wide range, you can purchase professional and domestic materials. Foam can be designed for use in the summer and winter, and for ease of application, you may prefer pistol or manual options.
The material contains freon, which is environmentally friendly and lack of shrinkage. There is no double expansion effect. If you cannot choose between household and professional foam, you should know that the difference between these two options is only in the design of the cylinder valve.
Application Reviews
Soudal foam, according to customers, has a fairly wide area of use. It can be used when installing stairs, doors and window sills. The material proved to be excellent, according to customers, when attaching wall panels and sealing panel joints. You can purchase this composition for:
- filling voids;
- heat insulation fasteners;
- pipe fixation;
- soundproofing screen formation .
Consumers, in their words, use the composition also for gluing roofing elements.
Usage Feedback
According to customers, the foam described in the article should be used according to the manufacturer’s instructions. If you familiarize yourself with it, you will be able to understand that the foam must be maintained for a certain time at room temperature before surface treatment. To improve the adhesion characteristics, the working surface must be additionally processed.
According to home masters, the surface should be cleaned of dust and dirt, and then moistened with water. Before starting manipulations, the protective cap must be removed, the gun connected, and then shake the container well. Sudal foam, the reviews of which you were able to read above, should be applied in the position of the balloon upside down. Excess material can be disposed of with acetone, Click & Clean or solvent. Frozen particles are removed mechanically.
The main properties of the material
The foam described in the article has high stability, it does not give secondary expansion and does not shrink. Among the abilities, excellent occupancy should be highlighted. Foam adheres to most building surfaces. It can be used for delicate and special installation work. Soudal foam, the technical characteristics of which were presented above, is sold in cylinders by:
The material is painted in the color of champagne. If storage is required, the containers should be placed in a cool, dry place. Shelf life is 12 months. For ease of use, the cylinders are equipped with a bayonet mount system. To fix the gun in the packing slot, a little pressure must be put on it. This system simplifies the work of craftsmen and allows for quick cylinder changes.
Reviews of the main varieties of professional mounting foams brand "Sudal"
Sudal polyurethane foam, the technical characteristics of which you must have studied before purchasing the product, as buyers emphasize, is sold in several varieties. If we are talking about professional options, you should pay attention to SOUDAFOAM CLASSIC GUN WINTER. This foam is suitable for winter installation work, because it can be used, as customers emphasize, at ambient temperatures up to -10 ° C. SOUDAFOAM MAXI ARCTIC is suitable for frosts down to -25 ° C. This product is improved, it is an innovative version of building winter foam.
If you need material with minimal expansion, then you should pay attention to SOUDAFOAM GUN LOW EXPANSION. This foam, according to customers, is designed to perform delicate installation work. The bayonet mount and minimal expansion has SOUDAFOAM GUN LOW EXPANSION CLICK & FIX foam. Consumers are advised to purchase SOUDAFOAM MAXI if you want to use a material based on polyurethane. In addition, this composition is characterized by an increased yield of the substance.
