Removable pressure-sensitive adhesives (PSAs) are used in the production of self-adhesive materials such as protective films, masking tapes or biomedical electrodes. This work presents a new and environmentally friendly method obtaining this type adhesive materials, i.e., photochemically induced free radical telomerization. Adhesive binders to removable PSAs, photoreactive acrylic telomer syrup...

The paper presents research on expedient repairs, including battle damage repair methods of hydro-pneumatic pipes with adhesives. According to analyzed publications concerning battle damage of military equipment, various pipes and lines, which are used in military vehicles and aircrafts, are one of the most often damaged parts during combat operations. During experimental tests, the efficiency ...

Based on several significant examples, we analyse the adhesion mechanisms at soft polymer interfaces with a special emphasis first on the role of connector molecules, that is, polymer chains bound to the interface and which transmit stress through a stretching and extraction mechanism, and second on the necessary relay that must be taken by additional dissipation mechanisms acting at larger sca...

The purpose of this research was to develop a matrix-type transdermal therapeutic system containing drug Diclofenac acid, Pressure Sensitive Adhesive (PSA) like acrylic adhesive by the solvent evaporation technique. Different concentrations of Labrasol, oleic acid and triacetin were used to enhance the transdermal permeation of diclofenac acid. Polyethylene monolayer film as a backing membrane ...

This paper focuses on an experimental study of the explosive decompression representative samples hyperbaric type IV hydrogen storage vessels. The adhesion composite to liner is achieved by different adhesives. bond behavior liner-to-composite bonded joint considerably depends properties adhesives, as well assembly process. X-ray tomography allows determining damages before and after tests. Tom...

Does the dryness of tooth surface influence the bonding efficacy of self-adhesive resin cement? I would like to know how much I should dry the tooth surface for better adhesion of self-adhesive resin cement. Q Self-adhesive resin cements are designed to adhere to the tooth substrate without a separate adhesive or etchant. The first commercial product, RelyX Unicem, was launched in 2002 and gain...

Purpose: To evaluate the technique sensitivity of four different adhesive systems using different air blowing pressure. [LP] (3M ESPE, USA) and an experimental adhesive, SSB-200 [SSB] (Kuraray, Japan). Twenty-four extracted molars were used. After grinding the coronal enamel surface, the teeth were divided into two equal groups. The first group's teeth were randomly assigned for bonding with th...
