Adhesive or sealant resin formulations can vary as well—by chemistry, viscosity, filler content, handling time, and moisture sensitivity, as well as other critical performance factors engineered by the material supplier. If a meter/mix system is chosen simply based on the mix ratio capability of the system, it will likely to fall short on capability to meet the application and production needs. Following are some key points to consider when choosing meter/mix equipment. Note de contenu : - Formulation and application considerations

Pompes à pistonRésumé : Upgrading production to two-component dispensing systems can offer multiple benefits.
With the continuous improvement of current metering and dispensing technology, two-component equipment proportioning and mixing precision can reach ±1%. Manufacturers that previously worried about the unstable performance of two-component dispensing equipment are now increasingly upgrading their production from single- to two-component in order to achieve the multiple benefits now offered by two-component adhesives and sealants technology, including: fast curing, chemical reaction curing (cures simultaneously from inside to outside), and better bonding strength and seal effects.
Two-component dispensing systems are widely used in the automotive, engineering machinery, appliances, LED, solar energy and other industries. The systems consist of a material transfer unit, metering unit, pressure stabilization unit and dispensing valve. In addition, automatic dispensing can be realized with the addition of an industrial robot and ¾ axle sliding table.Note de contenu : - Material handling

Ultraviolet (UV) light-emitting diode (LED) curing offers many benefits for bonding and coating applications in the touchscreen manufacturing segment. It provides a more consistent and reliable process without damaging or discoloring heat-sensitive components.
UV curing is a photopolymerization process that uses UV energy to change a liquid to a solid. Upon absorption of the UV energy, the photoinitiator (PI) produces free radicals that initiate crosslinking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink, coating, or adhesive, usually in a few seconds.
Originally introduced in the 1960s, today’s manufacturers use UV curing for a variety of applications—from graphic arts printing to automotive headlamp coating and more. In fact, the UV curing market continues to grow as it displaces water- and solvent-based thermal drying processes due to increased productivity, higher quality and performance, and environmental benefits.Note de contenu : - Fig. 1 : UV-curing photopolymerization process

Succinique, AcideL'acide succinique est un diacide carboxylique aliphatique, dénommé également acide butane-1,4-dioïque et de formule semi-développée HOOC–CH2–CH2–COOH.
Il est présent dans tous les organismes vivants et intervient dans le métabolisme cellulaire, en particulier dans le métabolisme des lipides entre l'acide cétoglutarique et l'acide fumarique lors du cycle de Krebs dans la mitochondrie.Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Bio-based succinic acid provides researchers and product developers a valuable and innovative sustainable platform chemical for differentiable, high-performance polyurethane (PU) materials. Bio-based succinic acid and its derivatives have demonstrated performance advantages in a variety of applications, including personal care products, non-phthalate plasticizers, and polymeric derivatives used in urethanes, polyesters, and alkyd resin technologies.
Figure 1 shows a schematic of the various synthetic pathways by which succinic acid can be transformed to diesters, diols, and high-molecular-weight polyesters and polyester polyols. Along with succinic acid, key succinate derivatives include polyester polyols,1,4 butane diol (BDO) and tetrahydrofuran (THF).Note de contenu : - Yeast fermentation process and LCA
