UV stabilizers, such as benzophenones, work by absorbing the UV radiation and preventing the formation of free radicals. Depending upon substitution, the UV absorption spectrum is changed to match the application. Concentrations normally range from 0.05% to 2%, with some applications up to 5%. Frequently, glass can be a better alternative to ...
The planters were bolted to the city streets in Playa Vista behind a Home Depot in an area popular with people who live in their vehicles. Planters illegally bolted to an L.A. street to deter RV ...
Higher molecular weight of the polymer chains provides higher tensile strength and heat resistance. Presence of unsaturated bonds makes the adhesive more susceptible to autoxidation and UV degradation and necessitates use of antioxidants and stabilizers. The adhesives are usually clear or translucent, colorless, straw-colored, tan, or amber.
