Neoprene Decorative glue (home convenience glue) FAQ

1. Is it normal for the bottom layer to precipitate after the chloroprene glue is placed for a long time?
A: In the production of neoprene adhesive formula, light magnesium oxide should be added. It is mainly used for curing crosslinking, anti-coke agent and resin chelation in neoprene adhesive. If it is normal to produce a thin layer of white sediment at the bottom of the adhesive container, it is abnormal to produce more suspended matter or white sediment. This is because the low content of magnesium oxide is easy to produce white suspended matter, the calcium content of magnesium oxide is too high, the activity is too poor, the fineness is not easy to produce precipitation, stratification.
 
2. Why can wire drawing occur when chloroprene glue is used?
A: In the glue process, drawing is very serious, forming bumps on the metal, leather is also all silk. This case may be due to gelatinization, will be in the process of use, daub uneven. Or solvent volatilization fast, leading to serious wire drawing. If it is caused by these aspects, it can be improved by diluting with a solvent such as toluene. Another factor is likely to be relatively high resin content, such as graft glue series have wire drawing phenomenon. Generally speaking, drawn neoprene adhesive belongs to the quick-drying type, which can be glued for a while.
 
3, in the construction of glue on the surface or hand how to remove?
A: Chloroprene adhesive on articles or human hands need to be removed, can be used to remove ethyl acetate, toluene, acetone and other mixed solution.
 
4. A customer uses the August home convenience glue with moderate viscosity. But with the December convenience glue, it feels like toothpaste, which doesn't flow easily and can't be used. Is there a quality problem, or is the rubber hose leaking?
A: The solvent system of Golianghao family convenience glue is not frost resistant. When the temperature is below -5℃, the viscosity of the glue liquid is obviously thickened, and slowly solidifies, and eventually becomes a paste without fluidity, that is, what the user says is like toothpaste. If this happens, the product can be placed in an environment above 20℃, the glue liquid can be automatically restored to the original state. The time used for recovery is related to the temperature and the amount of glue. If the temperature is high and the amount is small, the time used is short, and on the contrary, the time used is long.
