Material Description

Prior to polymerization, the sealant is a high quality one-component viscoelastic mass. After
applications with indirect exposure to moisture and air, the sealant polymerizes to form a strong bond.

Mode of application

Working temperature:

Application temperature from +5°С to +30°С.

Relative air humidity not less than 50%.

Foundation preparation:

The surface must be dry, free from dirt, dust, grease stains.

Work procedure:

Work should be carried out using manual or pneumatic guns, strictly following the instructions for use of the tool.

1. Insert the foil package into the gun, cut off the tip or paperclip with it, make sure that the applicator with the nozzle is fixed in the front of the gun. Tighten the front of the pistol body with force.

2. Fill the space with sealant in a slow and even motion, carefully filling the joint. Make sure there is no air left in the seam. Minimum Width seam from 4mm.

3. The time during which the sealant can be leveled with a spatula after application (pot life) is 15 minutes.

4. Final property set time 3mm per day (at +23°C and 50% humidity)

Storage

Storage temperature of closed packaging from +5°C to +25°C. Warranty period of storage is 12 months.

paintable

Where it is necessary to glue two surfaces with high quality, as well as to ensure their effective sealing, one cannot do without a special material - sealant. It is applicable to various kinds of materials, both wooden and metal surfaces, ceramics and concrete, and when solidified, it provides protection against the penetration of moisture and dampness, is able to dampen vibrations and prevent corrosion. Among consumers, TechnoNIKOL polyurethane sealant is especially popular, which is distinguished by high gluing and sealing ability, as well as excellent performance and durability.

Scope of application

Polyurethane sealant can be one-component, as well as two-component, but in any case, the main material is elastic polyurethane, which is similar in properties to mounting foam. Due to the moisture present in the air, it polymerizes and quickly hardens, acquiring a solid structure.

Attention! The sealant performs two important functions- it sticks together surfaces, that is, it works like glue, and also seals the seam, reliably protecting the surface from moisture and corrosion.

Due to its properties and characteristics, a sealant is often used for outdoor work, as well as internal construction and finishing works and applies to:

Polyurethane sealants are the most reliable of all materials used for sealing joints and waterproofing, which perform their functions even in conditions of high humidity and other adverse factors.

How to properly use and apply the sealant will tell the video:

Advantages

Among the main advantages of this building material are:

• Enough high level elasticity;
• Good adhesion to all types of surfaces (concrete, ceramics, glass, stone, metal, plastic, brick, etc.);
• High rates of self-adhesion;
• It is not affected by moisture, and does not change its bonding properties if it is present;
• Dries quickly and hardens (this property requires certain skills to work);
• Temperature changes do not affect the properties and characteristics of the sealing ability of the material (frost resistance up to -50 degrees, and the ability to work - up to -10 degrees);
• Ultraviolet does not have a destructive effect on the sealant;
• No shrinkage after drying;
• Economic consumption;
• Completely safe composition that does not emit harmful substances into the atmosphere and does not affect human health;
• Durability and practicality;
• Possibility of coloring with dyes water based, as well as a wide range of colors.

The presence of a large number of advantages of a sealant speaks of its versatility and popularity among the selected materials. Among the shortcomings, one can single out only the need to protect hands when working with it, as well as preventing exposure to it. high temperatures(more than 120 degrees).

Attention! It is best to apply a sealant to a material whose moisture index exceeds 10%, and when gluing plastic surfaces, buy a material designed specifically for this type of coating.

Properties and special characteristics

The main positive properties of polyurethane-based sealants include their high strength and durability, as well as the absence of aggressive environmental factors - mechanical damage, temperature changes, humidity, wind, etc. This material retains its properties well under water, which significantly expands the range of its application. But its main property is ease of use. This requires a standard construction gun, into which a sealant cartridge is inserted, and its tip is cut to the required diameter (depending on the size of the joint or the area of ​​\u200b\u200bthe bonded surface).

Regardless of the texture, when using polyurethane sealant, 100% adhesion of surfaces is observed, as well as high hardness of the seam and its strength.

Types of polyurethane sealants

Depending on the composition, polyurethane sealant can be:

Application features

Sealant can be applied in one of three main ways:

• Cold. In this case, the adhesive is applied to a clean, previously degreased surface. Apply the first layer and wait 10 minutes, after which the second layer is applied and the surfaces to be glued are pressed against each other;
• hot. The glue is applied to the surface, left for 30 minutes, and then heated to 80 degrees, and the surfaces to be glued are squeezed with a press;
• Wet. Before application, the surface is sprayed with water, and the interlocking parts are connected.

Other features of use include:

• Method of application - with a spatula, automatic or pneumatic gun, with or without battery;
• Compliance with safety rules when applying - the use of goggles, gloves, respirators;
• Surface cleanliness - before application, the surface must be cleaned of dust and dirt, and also degreased, previous layers of paint, oil, rust are removed;
• Mandatory moistening of the surfaces to be glued, otherwise the sealant will not be able to gain the necessary hardness and strength;
• uniformity of application;

Among other bonding and sealing materials, polyurethane-based materials have more advantages. This ensures their demand and popularity among building materials.

TECHNONICOL PU sealant is a high-quality one-component polyurethane visco-elastic mass, which is characterized by good plasticity and strong adhesion. After application, the sealant cures under indirect exposure to moisture and air to form a strong bond.

Color: grey.

Application

• elastic sealing of light metal and steel structures;
• sealing of ventilation ducts, silos, containers, reservoirs, etc.;
• filling and sealing expansion vertical and horizontal joints;
• sealing joints in concrete slabs, in cable and pipe penetrations;
• filling the upper limb of the edge rails.

Carrying out work

Insert the foil into the gun, cut off the tip or paperclip with it, then screw the front body of the gun tightly. Follow the instructions for using the gun.

Apply the polyurethane sealant in a slow, uniform motion, carefully filling the gap so that the joint is free of air. If necessary, smooth the seam with a spatula within 15 minutes after applying the sealant.

Not recommended for connections with polyethylene, polypropylene, Teflon and bituminous surfaces. Do not paint with alkyd paints. Do not apply to bare wood or damp substrates that may blister.
