Effects of shape The adhesive bonding of a tape or label can be affected by its shape. Tapes with pointed corners start to detach at those corners; adhesive strength can be improved by rounding the corners. Removal Removable adhesives are designed to form a temporary bond, and ideally can be remo... read more
Structural and pressure-sensitive adhesives Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adh... read more
Pressure-sensitive adhesive (PSA, self-adhesive, self-stick adhesive) is a type of non reactive adhesive which forms a bond when pressure is applied to bond the adhesive with a surface. No solvent, water, or heat is needed to activate the adhesive. It is used in pressure sensitive tapes, lables,glu... read more
Atmospheric corrosion Atmospheric corrosion is a process that occurs inside a wet film on the surface of steel structures. The wet film layer may be too thin to be visible to the naked eye.The following factors will cause the corrosion rate to increase: The rise in relative humidity;Condensation ... read more
Supply & Demand Dynamics Demand Demand for cementing services is directly driven by drilling, well intervention and plug & abandonment activities around the world. North America is the largest market for well cementing services, followed by Asia Pacific. The Middle East is one of the small... read more
