GlossaryLacquer:A clear or colored paint or varnish that cures by evaporation of a solvent.Masking:Application of material to prevent paint from reaching an area or component.Material Safety Data SheetA form with data regarding the properties of a particular substance. MSDS (materialsafety data sheets) are a widely used system for cataloging information on chemicals,chemical compounds, and chemical mixtures.Mixing Chart:Product preparation guide used to illustrate precise ratios of material that combine toform a usable coating.Nap:The raised (fuzzy) surface used describe the thickness and absorption characteristics ofa paint roller.Nozzle Size:Metric or Imperial measurement denoting the size of the opening where the paint exitsthe spraying device.Osmosis:The movement of molecules through a membrane or material from an area of greaterconcentration to an area of lesser concentration.Overcoat:Describes when a different product can be applied over an already applied coating.Additional coating of paint that interlocks with subsequent layers through adhesiveproperties.Overspray:Paint spray that adheres to an area outside the area targeted for coverage.Oxidation/Oxidizing:Corrosive process in which a material changes composition through a chemical reactionwith the air, water or other material.Paint:An applicable liquid which dries to a solid film through an evaporative or chemicalprocess for the purpose of decoration and/or protection of a substrate.Phenolic:A material or compound containing phenols (carbolic acid). Phenols are closely relatedto alcohol, but contain higher acidity levels.Polyester:Polymers which contain the ester functional group in their main chain.GlossaryPolymers:Plastics that are composed of large molecules with repeating structural units.Polyurethane:Any polymer composed of a chain of organic units joined by a urethane link.Post-cure:The process of heating a surface in order to expose the coatings and substrate to theworking temperature when the surface is exposed to the sun. This is typically done toprevent print-through.Pot Life:The period of time that a coating remains useful after opening or after a catalyst orother additive has been mixed. Also known as usable life.Primer:Coating applied to a surface or substrate to increase its binding and adhesion forsubsequent coatings as well as improving corrosion resistance for the underlyingsurface or substrate.Print-Through:(sometimes referred to as bleed-through) is a generally undesirable effect where theunderlying substrate is visible through the final topcoat of paint.Profile:The elevation or relief of a surface when viewed from the side.Protective Primer:A special grade of primers that contain additives that provide additional inhibitors tocorrosion. ALEXSEAL ® Protective Primers 161, 156 or 135 are uniquely formulated toprovide additional protection for metal substrates from corrosive elements.PSI:Pounds per Square Inch – a measurement of air pressure that is equivalent to 0.068947bar.Re-coat:Term describing when a second coat of the same coating product may be applied,typically without sanding.Reducer:A solvent material added to paint to lower the viscosity of the final material.Resin/Epoxy Resin:A hydrocarbon compound used in the production of varnishes, adhesives & coatings.Typically mixed with a hardener to create a very hard, durable plastic substrate usedcommonly in boat building.Rheology:The manner in which liquid paint flows over a surface.140ALEXSEAL ® Professional Application Guide version 0.4.3ALEXSEAL.COM > Europe: +49 0 40 75 10 30 > North America: +1 843 654 7755141
