Viscosity/Flow

The viscosity of an adhesive or coating can be modified to give it the correct handling characteristics for the application technique being used and the physical characteristics of the end use application. For instance, application of a thin gauge film coating using an offset roller technique will require a low viscosity, high flow product whereas cartridge application of grout or sealant requires a high viscosity, low flow product. Highly viscous materials have better sag resistance and stay in place after application. In other circumstances, a more fluid material is required that will either penetrate a porous surface or that will “self-level” to give a smooth finish.

Solids Content

Control of the solids content of solvent based adhesives and coatings is critical to their end use performance. The solvent in the formulation will evaporate from the material leaving the non-volatile components behind. These non-volatile components provide the chemical and physical performance of the adhesive or coating. The polymer will provide the majority of the physical characteristics such as bond strength and the other additives can provide other desired effects as outlined elsewhere. Increasing solvent levels will tend to reduce viscosity and increase flow within the adhesive or coating but at the expense of increase volatile organic compound (VOC) levels. The inclusion of fillers can increase the viscosity but at a lower total cost than using polymer or effect chemicals.

Cure Rate

Cure rate is how quickly the adhesive or coating delivers its final performance properties. Generally, when using solvent based adhesives and coatings it is necessary to allow the solvents to evaporate away before the bond or coating reaches its final performance. In some circumstances, it is necessary to include cross linking chemicals or other curatives to allow a chemical reaction to take place to provide full cure. The rate that this is achieved can be adjusted by using different solvent blends or by changing the type or concentration of the curing species or changing cure temperature, time and heat.

Switchable Adhesives

SWITCHABILITY describes the ability of an adhesive or coating to turn an effect on or off. HEAT REACTIVATABLE (HR) adhesives or coatings rely upon externally applied heat to make them sticky. This relies upon the thermal properties of the ingredients used in the adhesive. PRESSURE SENSITIVE (PSA's) have a naturally tacky finish which is usually protected with a release liner or layer to prevent them sticking to themselves. Once exposed, the coated surface will adhere to the intended surface by the application of pressure. LIGHT REACTIVATABLE or DEACTIVATABLE adhesives can be formulated to react to different wavelengths of light. This effect can be used to achieve a cure when exposed to a certain wavelength of light. This can prove useful when the adhesive is required to stay non bonding until the substrates have been carefully positioned at which point a rapid cure is required. Conversely adhesives can be formulated to break down or fall apart under a certain wavelength of light.

Surface Tension

Surface tension is the tendency of a liquid to form droplets. High surface tension results in spherical droplets when applied to a surface whilst low surface tension liquids are more likely to spread out over the surface. Controlling the surface tension of a liquid adhesive or coating is important in ensuring that the material adequately spreads out (wets) the surface of the substrate to which it is applied. Additives can be incorporated to adjust the surface tension and change the wetting characteristics of the coating or adhesive.
