Most varicose and spider veins appear in the legs due to the pressure of body weight, force of gravity, and task of carrying blood from the bottom of the body up to the heart. Compared with other veins in the body, leg veins have the toughest job of carrying blood back to the heart. They endure the most pressure.
Curing a thermosetting resin transforms it into a plastic, or elastomer by crosslinking or chain extension through the formation of covalent bonds between individual chains of the polymer. Crosslink density varies depending on the monomer or prepolymer mix, and the mechanism of crosslinking:
LED curing lamps for quick adhesive curing processes. When bonding, immediate and reliable results are crucial. LED curing ensures quick curing, hence supporting efficiency in production. DELO offers a range of industrial adhesives and LED curing lamps that are an optimum fit. This allows for easy and safe curing processing of light-curing adhesives. These glues harden optimally when exposed to UV curing light, which is 100 to 1,000 times as intense as natural light.
