Latex covalent additive

About video
Traditionally, solventborne formulations are used in this application, although waterborne coatings have several important benefits. Lower VOC emissions are the main reason for stricter regulations worldwide that push the use of waterborne solutions. In addition, waterborne coatings are less hazardous in the application as they do not emit hazardous fumes and odors, are not flammable, and equipment is safely cleaned up. Moreover, while specifically 1-pack waterborne latex formulations are easy to apply, their performance in light- and medium-duty applications is good, with excellent durability. The film formation process of 1K waterborne formulations does not involve a chemical crosslinking step.

The method of protein attachment is the other important consideration. The orientation and conformation of antibodies can dictate which method is most suitable. If physical passive adsorption is satisfactory, then the most common particle used is a sulfate microsphere. This is a very hydrophilic surface and allows ample adsorption sites for the hydrophobic sections of protein molecules. Covalent coupling via a two-step process is usually carried out using a carbodiimide to give an active ester intermediate.

Elastomers Presented by Michael S. Our elastomers are used across a variety of applications, including tyres, footwear, sports goods, rollers and mechanical fenders etc. Thermoplastic Elastomers Special Interest Group 4spe. Elastomers comprise a diverse range of chemical structures although they are characterized as having weak intermolecular forces. This reaction led to the development of fluoroalkanes, the precursors of fluoroalkenes, fluoroalkenes in turn led to halogenated refrigerants.

Rubber Photo by: Upsidedowncake Rubber is an elastomer—that is, a polymer that has the ability to regain its original shape after being deformed. Rubber is also tough and resistant to weathering and chemical attack. Elastomers can be naturally occurring polymers, such as natural rubber, or they can be synthetically produced substances, such as butyl rubber, Thiokol, or neoprene. For a substance to be a useful elastomer it must possess a high molecular weight and a flexible polymer chain.
