Q:What is meat adhesive?: Sodium alginate is particularly suitable for use as a meat adhesive.

Q:Glass glue is not what can stick ah, is the environmental sealant do ,,,: No, glass glue can only be used in glass and smooth metal, other parts are not suitable, and now most of the building materials market is the window does not leak polyurethane sealant, this sealant no matter what parts can be used

Q:Adhesive 252 on the human body what harm: Formaldehyde hazards: formaldehyde is colorless, with a strong smell of irritating gas, its 35% to 40% of the aqueous solution known as formalin. Formaldehyde is the original pulp poison, can combine with the protein, inhalation of high concentrations of formaldehyde, there will be severe respiratory irritation and edema, eye pain, headache, bronchial asthma can also occur.

Dizziness, mucosal inflammation, laryngeal pain, pulmonary edema, nausea and vomiting and other respiratory diseases, and excessive formaldehyde lead to female menstrual disorders, pregnancy syndrome, decreased fertility and neonatal chromosomal abnormalities, leukemia. Teen mental decline. Long-term exposure to low doses of formaldehyde pollution caused by nasopharyngeal carcinoma, brain cancer, colon cancer, high concentrations of formaldehyde also damage the immune system, liver system.

Q:What happens to concrete cracks in bridge construction?: Paste method This method can be used when the movement is more than one plane, or if excessive movement has exceeded the allowable range of a normal size groove, or when the slot can not be cut. Cover the crack with a flexible sealing tape and only stick the edge of the belt.

Q:What is the difference between RTV industrial sealants and adhesives?: Sometimes the same product can also be used both as a sealant and as an adhesive.

Q:I can not tell - Adhesive Adhesive Sealant Coatings and other chemicals, what are the same and different?: Adhesive refers to the homogeneous or heterogeneous surface of the object with adhesive technology together, with a continuous stress distribution, light weight, or sealed, the majority of the process temperature is low. Adhesive is particularly suitable for different materials, different thickness, ultra-thin specifications and the connection of complex components. Glue the rapid development of modern times, the application industry is very wide, and high and new scientific and technological progress and people's daily life has a significant impact. Therefore, research, development and production of various types of adhesives is very important. (The same adhesive)

Q:How do you define Henkel anaerobic adhesive products?: Many types, the main feature is anaerobic seal.
