Textile compound glue how to distinguish its good or bad?
Textile compound glue is generally large in volume. If it is not used up at one time, it must be well preserved and taken out next time. However, the leakage of textile compound glue is a common occurrence. In addition to its loose packaging, there are some external reasons. This stipulates that in order to better avoid the surface film of the strong glue, it should be sealed and stored after application. In order to better avoid leakage, it should be stored indoors to prevent freezing and sunlight.

Solvent-free laminating adhesives: trends in solvent-free adhesives
Solvent-free laminating adhesive manufacturers said that with the development of solvent-free compounding technology, many adhesive suppliers have introduced general solvent-free adhesives, cooking solvent-free adhesives, aluminum foil solvent-free adhesives, and low friction coefficient solvent-free adhesives. Although the diversification of products can meet the composite requirements of different materials, flexible packaging enterprises should frequently clean the gluing equipment and composite equipment according to the different adhesives used in different composite materials, which not only wastes time, manpower and financial resources, but also has low production efficiency.

Common sense of solvent-free laminating adhesive
Solvent-free adhesive manufacturers believe that solvent-free adhesive is one of the basic elements of the composite process, and its main impact is reflected in the whole process of production and use. Its main influence can be reflected in the following aspects or indicators, such as: 1) the range of the substrate and the use of the composite film; 2) working temperature and viscosity; 3) mix ratio and tolerance; 4) normal temperature viscosity and working viscosity (Working temperature);5) curing temperature and curing time; 6) transparency; 7) peel strength; 8) friction coefficient; 9) Functionality (such as retort resistance, medium resistance, etc.) 10) heat sealing strength; 11) weather resistance, etc.

Solvent-free laminating glue: problems in using solvent-free glue
Solvent-free laminating adhesive manufacturers said that the solvent-free adhesive will not volatilize VOCs, nor will it produce any irritating odor. At the same time, the problem of solvent residue in composite packaging is solved, the erosion of organic solvents on ink is eliminated, and clean production can be realized, which is conducive to environmental protection. Solvent-free composite equipment does not require a drying channel, reducing energy consumption. Moreover, in the later curing process, the curing temperature of solvent-free composite is basically the same as that of dry composite, so the energy consumption is relatively close.

What are the advantages and common types of PU adhesives?
In recent years, in order to meet the requirements of the lightweight development of auto parts, plastic parts are widely used in automobile manufacturing, especially high-strength FRP (glass fiber reinforced plastic) and SMC (sheet molding composites), so the advantages of PU adhesives and What are the common types?

How to use pu adhesive?
Pu glue, namely polyurethane glue, is a two-component adhesive made of resin and emulsion pre-polymerization. Mainly used for wood, aluminum, color steel plate and metal, polystyrene foam bonding. Good adhesive strength, no organic solvent, excellent heat resistance. The product can be cured at room temperature or by heating. In the final analysis is the plastic that we often say in our life, so how to use PU adhesive?
