1. Hand cream

If you can’t find alcohol, gasoline or nail polish diluent at home, you can try hand cream, which is available on the market. Many hand creams contain glycerin, silicone, and natural active agents. The above ingredients have the ability to moisten, penetrate, and dissolve the self-adhesive, and can quickly penetrate between the self-adhesive and the surface of the object to achieve the purpose of removal.

2. Nail polish remover and nail polish

For sticker marks on hard surfaces, such as stainless steel basins or glassware, first remove large pieces of label paper and use cotton swabs Dip a small amount of nail polish remover and apply it on the residue of the label. After waiting for a few minutes, wipe it back and forth with a soft cloth to remove it. Because nail polish remover is highly corrosive, it cannot be used on surfaces that are afraid of corrosion, such as paint. Surface furniture, laptop casings, etc. Nail polish and nail polish diluent have stronger dissolving power than alcohol and gasoline. When applied on labels, they can dilute and dissolve the non-stick adhesive.

3. Edible oil

If you want to remove self-adhesive labels from general objects, just wipe them with edible oil. Many self-adhesive label glues generally belong to the polyacrylate type. Pressure-sensitive adhesive, this kind of adhesive can swell in oil because its molecules are non-polar. Use a small spoon to scoop some oil and apply the oil evenly on the label. After 4-5 minutes, you can slowly tear it off from one corner of the label with your hands.

The cleaning principle of label adhesive: According to the composition of self-adhesive, we can know that the ingredients in pressure-sensitive adhesive are organic polymer compounds in the chemical field, and the viscosity is relatively high. According to the principle of isostructural miscibility of polymer chemistry, any organic solvent can dissolve the above-mentioned polymer compounds, such as liquor, essential oil, alcohol, gasoline, or nail polish diluent, which are all organic solvents, as well as facial creams and facial cleansers. Milk, detergent, and hand cream also have the same effect.

Extended information:

Label glue, also known as trademark glue, refers to the adhesive used to paste labels. It is divided into three types: pressure-sensitive glue, hydrosol and water-rewettable glue. kind.

Water-based label glue uses water as the solvent, and is mainly applied and adhered when used. It mainly includes polyvinyl alcohol modified glue, casein modified glue, etc.

Water re-enabling Label glue is mainly used for labeling or gluing small packages such as stamps and envelope seals.

Most label glues are of the pressure-sensitive type. Pressure-sensitive label glue is also called self-adhesive label glue, commonly known as self-adhesive. It is made of paper, film or special materials. , a composite material with pressure-sensitive adhesive on the back and silicon-coated protective paper as the base paper. The self-adhesive pressure-sensitive adhesive includes base material, tackifying resin, etc. According to the principle of isostructural miscibility of polymer chemistry, an appropriate solvent is used to dilute the base material or tackifier of the self-adhesive so that it can be easily separated from the adhered object.
