Kolorguide Fabric Marker Kit, Fine Point, Black, 12 Count, 12 Pack

Test pens help measure the surface tension to ensure proper adhesion for Flexo, Lab & Quality control applications A Dyne Test Pens Kit is a tool used to measure the surface energy of a material, with each pencil containing a liquid mixture usually containing water, alcohol, and a surfactant The level of wetting or dispersion of the liquid on the surface is used to determine the surface energy, measured in dynes per centimeter (dynes/cm) The surface energy of a material is an important property that affects its adhesion and bonding characteristics, with higher surface energy generally indicating better wettability and adhesion properties Dyne test pens are commonly used in the printing, packaging, and plastics industries to measure the surface energy of materials such as films, coatings, and adhesives, and to test the effectiveness of corona or plasma treatments on surfaces The Dyne Test Pens Kit (30-52) includes special liquid mixtures that allow accurate assessment of the adherence level of a liquid on a plastic surface These pens are mainly used in laboratories to measure the effects of corona treatment, and they offer a practical alternative to liquid mixtures Operators handling production lines use them to check if a material has undergone treatment These pens have a shelf life of six months and should be stored in a cool place Kolorguide provides high-quality dyne test pens and inks for the film, extrusion, and web converting industries, among others The kit comprises 12 standard dyne levels formulated from 100% reagent-grade materials, ranging from 30 through 52 dynes/cm, making it a versatile and reliable tool for professionals
