Abstract: This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with craft initiator which creates the reaction sites on the substrate via free radical mechanism.

Abstract: In an aspect, provided is an adjustable telescoping assembly. The adjustable telescoping assembly comprises a first support member and a second support member that is slidable upon the first support member and which defines an interior volume. At least one damping element is provided that extends from outside the second support member, through the second support member into the interior volume and engages the first support member.
