Today, under the Makroflex brand, more than ten names of various products are produced. These are adhesives, sealants, paints and varnishes, solvents and professional building tools. All of them are manufactured in accordance with international quality standards and meet sanitary standards. But the main product, the quality of which Macroflex is proud of, is foam.
On sale you can find several varieties of this product. Like other construction compounds, foam is produced for domestic and professional needs. Professional polyurethane foam, as a rule, is applied using a special gun - for a more accurate dosage and accurate application. Household - does not require additional devices, a plastic tube is attached to the cylinder for ease of use.
Polyurethane foam "Macroflex": technical specifications
The product of this brand is one-component, that is, initially ready for use, and does not require mixing of various components. It is based on polyurethane foam and other components. "Macroflex" - polyurethane foam, which is in the cylinder under pressure. When applied, it expands 2-3 times, and then hardens under the influence of moisture contained in the air. Depending on the external temperature, the width of the weld being filled, the expansion coefficient possessed by Macroflex is also determined. After hardening, the mounting foam becomes porous and densely elastic, provides excellent heat and sound insulation, repels moisture and prevents the formation of mold, fungus, and the penetration of microorganisms into joints and joints.
Scope of application
Macroflex is a mounting foam, the characteristics of which allow its use on various types of surfaces. Due to its high adhesion (this property provides good “adhesion” of the foam to the surface), it is used for wood, glass, stone, concrete and other building materials. In addition to the aforementioned resistance to moisture and its harmful effects, the hardened coating is resistant to acids and alkalis, however, it requires additional protection against UV rays.
Macroflex brand foam is perfect for sealing all types of joints and joints in the following types of work: installing door and window blocks, installing roofing, sealing engineering communications, and installing sound and heat insulation structures.
Recommendations for use
Macroflex is a mounting foam, the work with which, like with most other high-tech materials, requires strict observance of certain rules. The recommended temperature of the work is from +5 to +30 degrees. It is desirable that the width of the seam to be sealed is in the range from 1 to 6 cm, if the hole is larger, you must first fill it with a suitable insulation. The surface to be covered with mounting foam must be prepared in the standard way: clean from dirt and residues of old mounting materials, dry and degrease. In some cases, it may be necessary to treat it with spray water (if the humidity is not high enough for the foam to solidify normally).
Full vulcanization (hardening) of the assembly foam occurs within 3-4 hours. After that, its excess is cut off if necessary, and the seam is sealed with putty or painted.
