Basic knowledge of glass silicone sealant adhesives

1. Classification of silicone glass adhesives:

Silicone glass adhesives can be divided into two categories: one component and two components. A single component of silicone rubber, which is cured by contact with the moisture in the air, produces a change in physical properties; the two components are divided into groups of A and B two, and any group alone can not form a curing, but the two groups of glue will be cured once the mixture is mixed. At present, the market is often single component silicone glass glue, this book mainly introduces this kind of glass glue.

Single component silicone glass adhesive is divided into two types according to their properties: acidic glue and neutral glue. {TodayHot}

Acidic glass adhesives are mainly used for general bonding between glass and other building materials. The neutral adhesive has overcome the characteristics of acid adhesive corrosion of metal material and the reaction with alkaline material, so the application range is wider and its market price is slightly higher than that of acid glue.

A special type of glass adhesive on the market is silicone sealant. Because it is directly used in glass curtain wall metal and glass structure or non structural adhesive assembly, the quality requirement and product grade are the highest in glass glue, and the market price is the highest.

Two. A brief description of silicone glass adhesives:

Single component silicone glass adhesive is a kind of ointment. Once exposed to moisture in the air, it will solidify into a tough rubber solid material.

Basic knowledge of silicone glass adhesives

Silicone glass adhesive has strong adhesion strength, high tensile strength, weather resistance, vibration resistance, and moisture resistance, odor resistance and adaptability to cold and heat changes. In addition, its wide applicability can achieve the adhesion between most building materials, so its application value is very large.

Silicone glass glue does not flow due to its own weight, so it can be used to cross the top or side wall without subsidence, collapse or flow. It is mainly used in dry and clean metal, glass, most fat free wood, silicone resin, silicone rubber, ceramics, natural and synthetic fibers, as well as the adhesion of many paints and plastics. Silicone rubber glass with good quality will not be extruded or changed in physical properties when it is used below zero centigrade. The fully solidified silicone glass adhesive can still be maintained at the temperature to 204 (400oF), but the effective time will be shortened when the temperature is up to 218 (428oF).

Silicone glass adhesive has a variety of colors, commonly used in six colors: black, porcelain white, transparent, silver gray, gray and bronze. Other colors can be customized according to customer requirements.

Three, the use of silicone glass adhesives

(1) acid glass gum

1. It is suitable for sealing, plugging and preventing wind and rain. Both indoor and outdoor (indoor effect is better), the effect of seepage prevention and leakage prevention is remarkable.

2. Various kinds of interior decoration, including metal, fabric, organic fabric and plastic.

3. Connect the gasket on the heating and cooling equipment.

4. Add no screw hole reinforcement, nameplate and paint plus plastic material on the metal surface.

5. Seal the windows on the oven door, the flue on the gas appliance, the pipe joint and the access door.

6. Provide instant forming leakproof pads for gearboxes, compressors and pumps.

7. Seal the ship's warehouse and window.

8, the seal of the glass window of the trailer and truck cab.

9. Bonding and sealing equipment parts.

10. The antiwear coating is formed.

11, inlay and fill thin metal sheet overlapped, road network and equipment casing.

(two), neutral weather resistant adhesive

1, suitable for all kinds of curtain wall weatherproof sealing, especially recommended for glass curtain wall, aluminum plastic panel curtain wall, stone dry hanging weatherproof sealing;

2, joint sealing of metal, glass, aluminum, ceramic tile, plexiglass and coated glass.

3, joint sealing of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. In most cases, there is no need to use primer.

(three), silicone structural adhesive

1. It is mainly used for structural or non structural bonding between metal and glass walls of glass curtain walls.

2, it can connect the glass directly to the surface of the metal component to form a single assembly component to meet the design requirements of the full concealed or semi concealed curtain wall.

3, the structural adhesive seal of the hollow glass.

Four. Limiting conditions for silicone glass adhesives

Various silicone glass adhesives will be subject to the following restrictions when used.

1. It is not suitable for construction in the place where the water is soaked for a long time.

2, do not participate in the exudation of oil, plasticizer or solvent materials;

3, frosted or wet surfaces can't be glued to;

4, completely closed can not be solidified (silica gel depends on moisture in the air curing).

5, the surface of the base material is not clean or firm.

Acid glass adhesive has the following limiting conditions:

Acid silicate glass gum will corrode or not adhere to copper, brass (and other copper containing alloys), magnesium, zinc, electroplated metals (and other zinc containing alloys). It is suggested that acid glass is not used on the materials made of brick stone and the matrix of iron carbide, in PLEXIGLAS, polycarbonate, polypropylene, and poly (b). The use of the products made of enol and TEFLON (Teflon and polytetrafluoroethylene) will not achieve good bonding effect and good compatibility. The connection that is more than 25% of the width of the joint is also not suitable for the use of acid glass. It is better to use glass on the structure or to use acid glass (except acid structure glue). In addition, acid glass should not be used in the place where there is abrasion and there will be substantial defects. The surface temperature of silicone acid adhesive is over 40 C and is not suitable for construction.
