Secondary sealing stage of insulating glass isdesigned to protect the contour of the primary seal from mechanical and static loads and damage. Sealants, designed for use at this stage of insulating glass production are more varied. Conventionally, these sealants can be dividedinto two types: single-and two-component.

Two-components sealants are

• polysulfide based sealant Thiover A + B (Fenzi)
• polyurethane based sealant Poliver A + B (Fenzi)

Single-component sealants are

• silicone sealant on a neutral basis "MagicPro Silicone".
• sealant based thermoplastic butyl applied according to technology "Hot-Melt"

POLYSULFIDE BASED SEALANT

Polysulfide based sealant used in the production of insulating glass for many years. The most important advantage of them - is a low gas permeability, such as argon. There is no need to perform special measurements in the production of gas-filled insulating glass.

We offer you a sealant Thiover A + B (Fenzi). This sealant contains no solvents, has high adhesion to glass, aluminum, stainless and galvanized steel. Apply using the extruder.

POLYURETHANE BASED SEALANTS

Polyurethane based sealants are the most advanced sealing systems to date. They are absolutely identical with polysulfides on its mechanical properties, as well as in terms of gas-permiability.

We offer you a sealant Poliver A + B (Fenzi) - is a two component elastomeric solvent-free sealant based on polyurethane polymer, developed specifically for the production of elements made of insulating glass. Sealants Poliver made of different types to meet the individual requirements of the operator and the equipment used.

Poliver products are used to produce high quality items from the insulating glass. These products can be effectively applied to most mixers and metering machines.

SILICONE SEALANT

Silicone sealant on neutral basis "MagicPro Silicone" has excellent mechanical properties and has excellent adhesion to glass.

The advantages of one-component silicones, in addition, may include a neutral vulcanization, since it does lead to corrosion. However one-component silicones have a low rate of polymerization, which leads to an increase in the time of manufacture insulating glass. One component silicones have rather low steam and gas permeability compared with other sealant, which results in an increase in the applied layer of sealant.

Sealants Hotver 2000 (Hot-Melt)

"Hotver 2000" - a one-component, solvent-free sealant based on butyl rubber and synthetic polymers. Designed for ude in the manufacture of insulating glass. It has high adhesion to glass, aluminum, stainless and galvanized stell.

It is applied using extruder in the temperature regime of 170 - 190 degrees Celsius. The rapid solidification of the sealant provides a high performance of insulating glass assembly. No special methods for cleaning of equipment, unused remains of sealant are recyclable.

Technical characteristics

Color - black;
Density DIN 53217 - 1,13 g/cm³;
Operating temperature - 170 - 190 degrees Celsius;
Permeability to steam UNI 5611 - 0,21 g/sqm/d;
Packaging - 2 kg, 6 kg, 200 kg;
