SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The coating of foils, the printing of labels, or the gluing of electronic components are very different and demanding applications. However, they all require innovative production processes to maintain their appeal, durability and scratch resistance.
Great Britain-based Smith & McLaurin, a leading manufacturer and global supplier of self-adhesive labels, tags and tickets, was able to speed up and improve its production of labels by retrofitting a Heraeus Noblelight infrared system. Based in Johnstone, Renfrewshire, Smith & McLaurin sells reels of materials to printing houses and processors that manufacture finished labels and tags for a range of end users, such as supermarkets, pharmacies, logistics companies, and food-processing companies.Note de contenu : - Speeding the process

Traîtements de surfaceIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Whether bonding metal to plastic, silicon to glass, polymers to other polymers of different durometers, biological content to polymeric microtiter plates or even bonding to polytetrafluoroethylene (PTFE), plasma can be used to promote adhesion. Adhesion promotion can be achieved by increasing the surface free energy through several mechanisms, including precision cleaning, chemically or physically modifying the surface, increasing surface area by roughening, and primer coatings, according to Michael Barden of PVA TePla, a company that designs and manufactures plasma systems.

Titre : A fast guide to fast-curing floors : Methyl methacrylate (MMA) flooring systems offer many advantages for floor coatings Type de document : texte imprimé Année de publication : 2018 Langues : Américain (ame) Catégories : Colles:Adhésifs

Méthacrylate de méthyle
Revêtements de sols industrielsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Methyl methacrylate (MMA) flooring systems are fast becoming a popular choice for large-scale commercial and industrial construction projects due to their many advantages. Given the right conditions, an MMA floor can reach a full physical and chemical cure within only 60 min
of installation. This means that the surface can be subjected to full operational use under an extremely tight turnaround, especially when compared to the days or weeks that most epoxy, cementitious urethane, or concrete floors take to cure.
MMA systems derive this capability from the chemical formulation of the coating, in which a methacrylic ester is combined with an organic peroxide (usually benzoyl peroxide). The organic peroxide acts as a catalyst to quickly fuse the two components together into one solid, monolithic mass. This curing mechanism contrasts to epoxies and cementitious urethanes, which take time for the separate components to combine together to form a crosslinked matrix.
Along with speeding up the whole flooring project, this fast-acting nature can make MMAs a practical choice for a number of reasons. The way in which an MMA welds itself together means that it isn’t as sensitive to cold temperatures and moisture during the critical curing period. This allows for substantially sized areas to be easily completed in conditions as low as -20°F, which is ideal for an unheated construction site or a supermarket that needs to resurface a large cold store but that doesn’t want to waste time bringing the area’s temperature up and then down again.Note de contenu : - Application advantages
