What Are the Different Types of Glass Adhesive?

Glass glue is a commonly used adhesive in the family. It is composed of sodium silicate and acetic acid and organic silicone. Sodium silicate is easily soluble in water and is sticky. It is called water glass in the south and phylloline in the north.

Glass glue storage method

Glass glue should be stored in a cool, dry place, below 30 . Good quality acid glass glue can ensure the effective storage period of more than 12 months, general acid glass glue can be stored for more than 6 months; neutral weathering and structural glue can guarantee the shelf life of more than 9 months. If the bottle has been opened, please use it up in a short time; if the glass glue is not used up, the plastic bottle must be sealed. When it is used again, the bottle mouth should be unscrewed to remove all obstructions or replace the bottle mouth.

Note on glass glue

1. The most common problem of glass glue is the change of black mold. Even using waterproof glass glue and mold resistant glass glue can not completely avoid such problems. Therefore, it is not suitable for construction in places with long-term water or soaking.

2. Anyone who knows glass glue should know that glass glue is an organic substance, and it is easily soluble in organic solvents such as oil, xylene, acetone, etc. Therefore, glass glue cannot be used on substrates containing such substances.

3. Ordinary glass glue must be cured with the participation of moisture in the air, except for special and special purpose glass glue (such as anaerobic glue). Therefore, if the place you are applying is closed and extremely dry, then ordinary glass Gum will not be competent.

4. The surface of the glass glue to be adhered to the substrate must be clean, and there must be no other attachments (such as dust, etc.), otherwise the glue will not adhere firmly or fall off after curing.

5. Acidic glass glue will release irritating gas during the curing process, which has the effect of stimulating the eyes and the respiratory tract. Therefore, be sure to open the doors and windows after construction, wait for the curing to be completed and wait for the gas to be released.

Glass glue removal method

1. When the acid glass glue is not cured, whether it is sticking to the human body, utensils or clothing, it cannot be removed by washing with water, and it should be wiped off with a dry cloth.

2. Then there is the cured glass glue, which is extremely difficult to remove. If the cured glass is attached to glass, ceramics, metals, etc., you can consider scrubbing with solvents such as xylene, acetone (if you don't know these two substances, you can consider banana water, because banana water contains these Material), if there is less curing glue attached to the glass and other items, you can also consider scraping it off with a spatula. If it is attached to clothes, you can consider brushing it. If not, you should consider banana water.

3. There is also a case where the glass is glued to the hand and cured. In this case, don't worry, the handling is very simple. The glass glue is not sticky after curing, so rub it with your hands a few times to remove it.

Buying points of glass glue

The glass glue commonly used in home decoration is divided into two types according to performance: neutral glass glue and acid glass glue. Many people do not understand the properties of glass glue, so it is easy to reverse neutral glass glue and acid glass glue. Customers often say "come for two bottles" without mentioning the purpose. A person who has been engaged in the sales of glass glue for a long time said that this is the biggest problem in using glass glue in home decoration.

The places where glass glue is generally used in home furnishings are: dumb mouths on the back of wooden lines, sanitary ware, toilets, toilet mirrors, gaps between sinks and walls, etc. These places need glass glue with different properties.

Neutral glass adhesive is relatively weak, and is generally used in the back of the bathroom mirror where these places do not require strong adhesion. Neutral glass glue is more commonly used in home decoration, mainly because it does not corrode objects, and acid glass glue is generally used at the dumb mouth on the back of wooden lines, and has strong adhesion.

There is another important point when using glass glue: be sure to prevent mildew. For example, a lot of glass glue is used in the bathroom. The bathroom is very wet and easy to mold, so the glass glue must be mildew-proof. It is usually stated on glass plastic bottles. In addition, some poor quality glass glue does not have such a function at all, so be sure to recognize it when buying.

Identification method of glass glue

There are many types of sealants: silicone sealants, polyurethane sealants, polysulfide sealants, acrylic sealants, anaerobic sealants, epoxy sealants, butyl sealants, neoprene sealants, PVC sealants, and Asphalt sealant.

Buy sealant mainly depends on several properties: First, the breaking strength (pulling force / cross-sectional area); Second, the bonding strength (pulling force / bonding area, except for the destruction of the substrate); Third, the fracture elongation Elongation (length / original length when broken); four, anti-aging ability; five, appearance (mattness, particles, bubbles); six, shape (no drawing, facade does not sag); seven, shelf life; Eight, curing time.

There is no distinction between good and bad glass glue, and the performance corresponds to the price, which suits the best. Secondly, there is stability and sufficient quantity, which is a test of manufacturers. If the capacity of the sealant is less than the standard capacity (note: it is the capacity. This situation of the sealant is very serious), such a sealant is eliminated first. Such a company has a problem in its business thinking and the product is not much better. (There are also many problems, which prove that its product production process is not tightly controlled). If the amount is large, the production stability of the sealant must be considered.

Development trend of glass glue

The production technology of solvent-based glass glue two-component polyurethane adhesive glass glue for general compounding in China has been completely mastered. Some manufacturers have mature technology and stable quality, which can completely replace imported products. Some domestic manufacturers of solvent-resistant compounding solvent-based glass glue two-component The production technology of polyurethane adhesives has passed the standards. After years of promotion and application, it has shown that the product quality is stable and the price is reasonable, and it can replace imported products. Products such as aluminized film special glue and anti-slip agent functional glue are highly targeted and have outstanding performance. They should be promoted vigorously. The climate is obviously different, and the conditions of composite equipment are different. Composite manufacturers should choose suitable adhesives. Glass glue; China has joined the WTO. Composite manufacturers should pay attention to improving technology, updating composite equipment, cooperating with the promotion of environmentally-friendly adhesives, and breaking environmental protection technologies. Barriers to adapt to the requirements of global development; adhesive development units and manufacturers should accelerate the development of environmentally friendly alternatives, so that the comprehensive performance of products meet the composite requirements; industry associations should improve product inspection methods and methods, and accelerate the formulation of product industry standards to establish technical barriers Protect the people Industry.
With the continuous development of China's economy and the continuous improvement of people's quality of life, the market has increasingly higher requirements for glass glue products. Good performance, high quality, and environmentally friendly glass glue products will be loved by people. Glass glue manufacturers and scientific research institutes should increase investment in science and technology and actively research and develop new high-performance, high-quality glass glue products in response to market demand in order to respond to domestic and foreign market competition. ^[3]
