3 Join the UV revolution with Silcolease Silcolease UV curing systems offer flexibility to coat filmic and other heat sensitive substrates that is not possible with thermal cure systems. Energy costs are low compared to thermal systems and space taken by installation is small, making UV an option for speciality users. UV systems are the silicones of choice for: Heat sensitive films ver coating of printed surfaces Liner recycling Linerless labels Narrow web applications with limited space for drying sections The most sustainable silicone curing technology The photopolymerisation curing process of Silcolease UV systems render them safe to use and a responsible choice. Benefits for you include: Use of solventless and waterbased system to lower VC emissions Compact and simple machinery Safe products : no odor and no toxicity Low energy consumption Reduction of total cost of operations Silicone solutions for liners for the last 40 years What are the main applications for Silcolease UV systems? Labels Industrial, manufacturing, food and beverage, cosmetics and many other industries depend on our silicones for pressuresensitive labels of all shapes and types. Commonly used for product identification and decoration, these selfadhesive labels peel off siliconecoated paper backing with ease. Tapes ur silicones are designed to work with a variety of substrates and materials, including films, papers, poly foams, metal foils, fabrics, scrims and more. From nonstick coatings to adhesives resistant to high temperature, we have the solution for your speciality tape. Hygiene Hygiene products whether for feminine or baby care must be completely reliable and secure for consumers, this is why silicones with their outstanding selfadhesive properties are widely chosen as adhesive strip protections. We supply high quality products that comply with biocides, ReACH and skin contact regulations for the safety and the wellbeing of our endusers. Linerless labels Linerless labels are pressuresensitive labels that do not have a liner or backing paper. The labels are wound on a roll that has had a coating applied to the front of the facestock to prevent the adhesive from sticking on the label below. Main reasons for the growth of linerless labels is environmental pressure. Not only is the amount of label waste significantly reduced, but so is paper consumption, freight, and storage costs, as well as the cost of waste disposal. UV free radical curing mechanism is the most adapted technology for coating on heat sensitive substrates and avoid any risk of activating the ink. Why should you choose Silcolease Solventless UV range? Very fast cure Very long bath life Excellent anchorage on films Low or no thermal input to substrate Low substrate inhibition Readytouse monocomponents Silcolease UV range comply with skin contact regulations After complete curing, at the conditions recommended in the technical data sheets our UV Silcolease systems should satisfy the EU directive regulating the skin contact.

4 Two types of chemistry mechanisms: Free radical vs. Cationic curing Silcolease UV 100 series: Elkem Silicones coating free radical system, based on acrylate functional silicone polymers with a free radical curing mechanism. R R n M CH CH 2 R R RM n Free radical UV curing systems are sensitive to oxygen inhbition Silcolease UV 200 series: Elkem Silicones coating cationic system, based on epoxy functional silicone polymers with a cationic curing mechanism.

The major advantage of these products is their excellent cure and anchorage behaviour on almost any substrate. This means that they can be used on a wide range of speciality films. Their robustness to cure onto printed surfaces makes them the ideal candidate for linerless label applications. All classic solventless coating techniques are feasible. Heated coating units are frequently used to reduce viscosity and coatweight. ne drawback with the free radical technology is that the reaction is inhibited by atmospheric oxygen. These systems must be processed under an inert atmosphere with nitrogen blanketing.

The major advantage of these products is their excellent cure response to UV C radiation due to the incorporation of patented Iodonium Borate photoinitiator technology. All classic solventless coating technics are feasible. Heated coating units are frequently used to reduce viscosity and coatweight. A unique feature of Elkem Silicones Silcolease UV 200 series is the possibility to supply a readytouse single component without additional bath formulation. A range of base polymers offers flexibility for coating head and substrate variations. The control additives (RCAs) are used to modify the towards premium or tight values.
