Amine synergists are an intrinsic part of most radiation curable formulations that rely upon radical species to bring about polymerisation. They have two potential roles to play in the polymerisation process. One important role is as a co-initiator when used with ketones, usually aromatic ketones. The other very important role is as addit

There are three main stages for dispersion of pigments in paint, ink or coating solutions; pigment wetting, grinding, and stabilization of pigments suspension. During the initial pigment wetting stage, the moisture on the surface of pigments and air trapped within pigment agglomerates.Extent of wetting depends on viscosity of the solution and surfa

The discovery of contamination with Isopropyl Thioxanthone (ITX) in various Nestlé baby food brands in 2005 caused a huge stir in the European food packaging market. Millions of liters of product had to be withdrawn from store shelves. At that time, ITX was used as a photoinitiator in UV curable printing inks on the outer surface of liquid milk car

Fluorinated surfactants are an indispensable tool for UV-coatings due to their unique abilityto reduce surface tension leading to unparalleled wetting, leveling and hydrophobic surfaces.Recent health and environmental concerns of long-chain perfluorinated surfactants in regardto their bioaccumulation and toxicity resulted in intensive research and

Polyurethane acrylates belong to the high-performance UV coatings class. The polymer backbone is polyether, polyester or polycarbonate. By adding isocyanates and hydroxy acrylates at the polymer backbone the resulting polyurethane acrylate binder can be crosslinked via their acryloyl groups. Polyurethane itaconates are an alternative to polyurethan

Fluorine polymers commonly referred to as fluoropolymers, can greatly enhance the properties of coatings used in modern industrial; house hold and construction products. The qualities of fluoropolymer resins and oligomeric additives make them an ideal solution for applications requiring a high resistance to solvents, acids and bases, high thermal s

A wide variety of polymers are used as resins in coatings systems. Often defined by their reactive groups, the myriad of resins offer a wide-range of properties. In the coatings industry acrylate, epoxy, urethane and polyester coatings are all quite common and have associated typical properties and expectations. Resin manufacturers have spent count
