The market is commonly available polyurethane glass adhesive and silicone glass adhesive, two products.

Polyurethane glass adhesive elongation at break is generally about 450%, silicone glass adhesive is generally about 250%.

These two are quite good, but the polyurethane glass adhesive is a little better, the reason why the car with polyurethane glass adhesive is for this reason.

1, single and double component classification:

Silicone glass adhesive from the product packaging can be divided into two categories: single-component and double-component. Single-component silicone adhesive, its curing is by contact with moisture in the air and produce a change in physical properties; two-component refers to the silicone adhesive is divided into A, B two groups, any one group alone can not form a curing, but the two groups of slurry once mixed to produce curing. Commonly found on the market is a single-component silicone glass adhesive.

2, acid and alkali classification:

Silicone glass adhesive according to the nature of acid and alkali is divided into acidic and neutral adhesive two. Acidic glass adhesive is mainly used for general bonding between glass and other building materials. Neutral adhesive to overcome the acidic adhesive corrosion of metal materials and alkaline material reaction characteristics, so the scope of application is wider, its market price is slightly higher than the acidic adhesive. The market is more special class of neutral glass adhesive is silicone structural sealant, because it is directly used for glass curtain wall metal and glass structure or non-structural bonding assembly, so the quality requirements and product grade is the highest in the glass adhesive, its market price is also the highest.

3, color classification:

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

4, weathering adhesive, mildew classification:

Weathering silicone sealant is suitable for a variety of curtain wall weather sealing, especially recommended for glass curtain wall, aluminum composite panel curtain wall, stone dry hanging weather sealing. Weatherproof sealant is suitable for metal, glass, aluminum, ceramic tiles, plexiglass, coated glass between the joint sealing; weatherproof silicone sealant concrete, cement, masonry, rock, marble, steel, wood, anodic treatment of aluminum and painted aluminum surface of the joint sealing. No primer is required in most cases.

Anti-mold silicone sealant is the trend of the future, there is anti-mold effect of silicone adhesive than the general adhesive use longer, more solid, not easy to fall off, especially for some humid, easy to grow mold environment, such as bathrooms, kitchens and so on.
