①BOPP / VMCPP The composite structure is mainly used in the field of light food packaging such as instant noodles, egg yolk pie and snow cake. The composite structure is most suitable for one-component aqueous adhesives. Compared with solvent-based polyurethane adhesive, single component water glue less ink transfer phenomenon, and the initial adhesion is high, without aging, can be directly cut b...
Pressure sensitive adhesive (PSA) is a self-adhesive material, only need to apply a small pressure, can form a van der Waals force on the surface of the two objects, and the adhesive is firmly bonded, this pressure sensitive bonding performance is its basic feature, is also different from other adhesives typical characteristics. PSA can be divided into solution type, emulsion type, photocuring typ...
1.Water as a dispersion medium, do not use organic solvents, non-toxic or flammable danger, is environmentally friendly products; 2.Acrylic monomers have many types, containing ester groups, carboxyl groups, hydroxyl groups and other functional groups have strong polarity, it is easy to emulsion copolymerization with other monomers such as vinyl acetate, styrene, vinyl chloride, etc., to make emul...
The primer sprayed on the plastic surface can promote the effective adhesion between the glue and the material, increase the adhesion between the adhesive and the plastic, and solve the problem of degumming, and the main role of the primer is to solve the problem of degumming in the adhesive process. One: The definition of primer? The base coating agent is a base coating treatment agent that assis...
Composition of adhesive Adhesives are adhesives that can bond two objects together, referred to as glue. There are different types of adhesives according to different divisions, the use of adhesives is also quite extensive, and now it has been filled in our lives, for adhesives, do you know how it is composed? How adhesives are composed: Synthetic adhesive Synthetic adhesive is composed of main ag...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
