Comparison of true and false nail free glue

Nail free glue, judging from its name, "free" indicates its existence state; "Nail" explains its nature. Nail free adhesive is a strong adhesive for multi-functional building structures. It is generally called liquid nail in foreign countries and nail free glue in China.

At present, there are two kinds of common nail free adhesives in the market:

1. One is the neoprene type nail free adhesive originally from the all-purpose adhesive, but in fact it is defined as a fake nail free adhesive, because it is not a real new product, but is filled and improved by adding other chemicals on the basis of the original neoprene adhesive.

2. The other is natural synthetic rubber nail free adhesive, which is the foreign standard of nail free adhesive.

Although both of them belong to nail free adhesive, they are very different in quality and characteristics.

Smell difference: Neoprene has pungent smell, like "banana water" for decoration, commonly known as "Tianna water". Some businesses add a lot of flavors to their products to cover the original taste, but this pungent aroma is actually not conducive to health. At the same time, it is still essentially a kind of all-purpose glue, containing methanol and other substances, which is harmful to human body.

Color difference: in terms of color, the color of neoprene nail free adhesive is coffee, but after drying, the coffee color is limited to the surface, and porcelain white will appear once polished. Some businesses add additives to make them white. However, the additives have strong chemical composition, which is not conducive to human health. The natural synthetic rubber nail free glue is basically light porcelain white, beige and higher-grade transparent. There is absolutely no deep coffee and other colors. It can provide personalized customization in terms of color and produce different colors that meet the needs of customers.

Fixed line time difference: in terms of curing time, neoprene nail free adhesive has a long curing time, which takes 3 to 4 days to fully cure, and it must be fixed by external force in the first few minutes, otherwise it will slip; In contrast, the curing time of natural synthetic rubber nail free adhesive is fast. It only takes 17 hours to completely cure. It can be stuck basically once coated without sliding and displacement.

Performance difference: in terms of performance, neoprene is brittle and has no toughness. It is easy to crack or break outdoors with large temperature difference. In addition, neoprene is not resistant to high temperature and corrosion. When just extruded, the colloid surface is very rough and has no sense of delicacy. Natural synthetic rubber has good toughness and can withstand thermal expansion and cold contraction with large temperature difference. When extruded in contact with air, it naturally forms a very smooth film package on the surface of rubber, which can better adapt to changeable modeling. The colloid is smooth without particles, and the color is white, which is very eye-catching.

In this way, the standard to distinguish the good and bad of nail free adhesive lies in whether the nail free adhesive is natural synthetic rubber. Although the price of neoprene nail free adhesive is cheap, it can not be separated from the framework of universal adhesive. It is not a real nail free adhesive. It is not as convenient to use as a real nail free adhesive, and it is more likely to cause harm to human body. The natural synthetic rubber nail free adhesive is a new product in the real sense. It is easy to use, safe and environmental protection, no pollution, and has excellent weather resistance. It can easily deal with heat, cold, blister and oil stain, and can maintain the adhesion for a long time without worrying about the loosening, falling off or even cracking of the bonding part.
