Although the adhesive is only the supporting material in the building decoration, it does not mean that it is not important.A large number of materials in the actual decoration (such as wallpaper, all kinds of flooring, ceramic, stone decoration materials, etc.) are laid by pasting method, so the choice of appropriate adhesive directly affects the firmness of the laying, but also affects the decorative effect of the face.When choosing an adhesive, we should first understand its basic technical properties, which are the basic conditions to ensure the degree of bonding. 1.Processability refers to the performance of the adhesive related to the bonding operation, including the modulation, gluing, drying and curing conditions of the adhesive, and also the evaluation of the difficulty of the bonding operation.As mentioned above, multi-component adhesives should be deployed on the spot, chemical reaction adhesives have temperature conditions for curing reaction, solve-based adhesives need to be aired for a period of time after coating, until the solvent volatilization can be bonded and so on. These problems must be clear when choosing to use adhesives to ensure the bonding effect. 2.Bonding strength is to ensure the degree of bonding firmness performance indicators.The bonding strength is not enough, it will make the adhesive fall off, if the wall decoration, the adhesive will fall down, not only affect the quality of decoration, sometimes cause injury accidents. 3.Stability refers to the degree of strength change of the adhesive specimen after being immersed in the specified medium at a certain temperature for a period of time.Such as water resistance, oil resistance, etc. The measured strength is usually expressed or expressed by the strength retention rate. For the adhesive that wants to bond the ground, exterior wall or bathroom, toilet and so on the surface material, want to have very good stability. 4.Durability (or aging resistance) With the growth of the use of adhesive layer, its performance will gradually aging, until the loss of bonding strength, this performance is called durability.Because the largest amount of adhesive is now synthetic resin or synthetic rubber based on organic polymer materials, easy to aging in the process of use, so that the adhesive layer lost effectiveness and fall off. 5.Temperature resistance refers to the change in the performance of the adhesive in the specified temperature range. Including heat resistance (in high temperature environmental conditions), cold resistance (in low temperature environmental conditions) and resistance to high and low temperature change performance.These temperature changes will change the composition of the adhesive, so that the bond strength is reduced, until the adhesive layer falls off. 6.The weatherability is aimed at the adhesive parts exposed to the outdoors, which can withstand the weather, such as rain, sunshine, wind and snow and water wet performance, called weather resistance...

The composition structure of pressure sensitive tape Under normal circumstances, the composition of single-sided tape structure is: the release of the substrate, adhesive. The following image: Categories of adhesives and their respective properties The main adhesives are acrylic rubber, natural rubber, synthetic rubber, silicone and so on. For different application requirements, coating on the established release substrate. For the above adhesive characteristics comparison: Acrylic adhesive Advantage: Strong resistance to aging Strong weather resistance Strong temperature resistance It usually has strong resistance to shear force at high temperature Good adhesion to polar surfaces Disadvantage The initial peeling strength is low The adhesion to non-polar surfaces is poor High cost Natural rubber Advantage The initial peel strength is high It has strong resistance to shear force at high temperature There are adhesive forces on all kinds of surfaces Disadvantage Poor aging resistance Poor solvent resistance Higher cost Synthetic rubber Advantage There are adhesive forces for various surfaces, and non-polar surfaces are relatively better The initial peel strength is high Low cost Disadvantage High temperature resistance is very poor Poor aging resistance Poor weather resistance Water Based Pressure-Sensitive Adhesive For BOPP Tapes SA-227 Water based acrylic adhesive is designed for BOPP tapes. Good leveling, excellent holding power and high peel strength. It is suitable for kinds of adhesive/glue tapes. Sinograce Chemical has good quality, excellent price of acrylic adhesive used in packaging tape, exported to the world, welcome more customers to consult.

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 assists the adhesive and the substrate to form a good bonding layer in the field of industrial bonding, and acts between the base material and the adhesive by spraying or brushing and other construction methods. Common in practical industrial applications are: improving the base coating of PP plastic automotive interior parts and polyurethane glue, improving the base coating of nylon plastic and hot melt adhesive and other types of materials and different adhesives between the base coating. Two: the application effect of primer The base coating agent has good compatibility with the adhesive and the substrate, has good stability to heat and light, and enhances the adhesion between the adhesive and the substrate. Through wetting and intermolecular force, the free energy of the substrate surface is adjusted to improve the physical properties of the substrate and the bonding strength of the adhesive as an intermediate layer. The base coating agent optimally combines the difficult base material with the adhesive, and plays the role of laying foundation and linking for the formation of a firm adhesive layer. Three: application process of primer 1.First clean the surface of the plastic substrate, and then evenly coat the surface of the substrate by spraying or brushing. 2.The film thickness of the general primer is 3-5μm, and it is naturally dry. If there are baking conditions, it can be baked at 60-70 ° C for 3-5 minutes (baking helps to improve the effect of the primer). 3.Apply adhesive again. After the adhesive is baked and dried, place it in the air for 2 hours to test the adhesion Four: The use of primer precautions? 1.The use of primer requires a preliminary sample to determine whether it plays a role in enhancing bonding, and the general detection methods include 100 cells and stripping, pulling and other tests 2.Second, when coating the substrate, the entire surface of the substrate needs to be covered completely and evenly, and the cleaning process of the substrate needs to be carried out before construction. 3. Due to the different molecular structure and properties of the substrate, different substrates need to be used relative to the substrate. The application of primer in plastics can effectively solve the problem that many plastic surfaces are not attached to adhesives, and greatly improve the application effect of plastics.
