The Dymax Edge O l i gomers. Adhesive s. C o a t i n g s. E quipment. One priceless r e s o u r c e. T h a t s t h e D ym a x E d ge. At Dymax, we re committed to providing our customers with the solutions they need for their specific application challenges. Inherent in the Dymax Edge approach is the commitment to view a customer s challenge differently by listening, focusing, and using an entire toolbox of resources and expertise to deliver the most efficient solution. This expertise isn t limited to the formulation of chemistry or the calibration of a machine. Rather, it s defined by a depth and breadth of knowledge that allows us to devise innovative solutions based on an optimal balance of material, chemistry, and equipment. The Dymax Edge is more than the combined resources of product, technology, and service. It s the fundamental belief that you best serve a customer when you look at the need from their perspective, not yours. 2 UV Light-Curable Adhesives, Coatings, and Encapsulants for Electronic Assembly

Dymax Materials for Electronics Assembly Dymax one-part, solvent-free, UV light-curable electronic materials cure in seconds upon exposure to UV/Visible light and can be used in a wide variety of applications for circuit protection and electronic assembly. The products are electrically insulating and are designed for various operations including conformal coating, encapsulation, bonding, keypad coatings, thermal management, masking, and display bonding and lamination. Most products are available in multiple-viscosity grades, so the material flow may be tailored to the individual application. For shadowed areas, several cure options are available, including Dual-Cure light/moisture cure and Multi-Cure light/heat cure technologies. IPC approved, MIL-I-46058C, and UL listed self-extinguishing grades are also available. Wire Tacking Encapsulation Thermal Interface Staking Ruggedization/Cornerbond Reinforcement Encapsulation Glob Top Encapsulant Masking Peelable Mask Conformal Coating Cure-In-Place Gasket Strain Relief Environmental Benefits of Dymax Light-Curable Materials Dymax understands that safe, ecologically friendly products benefit our customers, the environment, and us. We have created materials with attributes that lower product costs, life-cycle costs, and ecological impact. These attributes include: Solvent-free materials -free materials RoHS compliance REACH - no substance of very high concern (SVHC) Eco-friendly, one-component materials Dymax -Free conformal coatings, encapsulants, and adhesives are documented by an independent laboratory to meet or exceed standards set forth in IEC 61249-2-21. This international directive defines halogen-free as <900 ppm for chlorine, <900 ppm for bromine and <1,500 ppm total level of both combined. The current test method used for certification is BS EN 14582:2007. UV Light-Curable Adhesives, Coatings, and Encapsulants for Electronic Assembly 3

Dymax Adhesive Technologies See-Cure Technology Dymax light-curable adhesives with patented See-Cure technology have built-in cure validation that makes it easy for operators or simple automated inspection equipment to confirm cure without investing in additional specialized equipment. See-Cure technology is an indicator of cure that intentionally transitions the color of the adhesive after it has cured and builds a visible safety factor into the assembly process. Ultra-Red Fluorescing Technology Ultra-Red fluorescing technology, formulated into Dymax adhesives, enhances bond-line inspection processes and product authentication. The adhesives remain clear until exposed to low-intensity UV light at which point they fluoresce bright red. This is particularly effective while bonding plastics that naturally fluoresce blue, such as PVC and PET. Ultra-Red technology also produces a unique spectral signature that can be used by manufacturers for product authentication. Multi-Cure Light/Heat-Cure Technology Multi-Cure adhesives combine the high-speed cure of UV or UV/Visible light with secondary cure mechanisms that enhance polymerization. Secondary cure mechanisms, which include thermal (heat) cure or activator cure, are useful when light can only reach a portion of the bond line, or when tacking a part prior to thermal cure to allow easier handling and transport during the manufacturing process. Dual-Cure Light/Moisture-Cure Technology Dual-Cure coatings are formulated to ensure complete cure in applications where shadowed areas on high-density circuit boards are a concern. Previously, areas shadowed from light were managed by selective coating eliminating the need to cure in shadowed areas or a secondary heat-cure process. Shadowed areas cure over time with moisture, eliminating the need for that second process step or concerns of component life degradation due to temperature exposure. LED Light-Curable Adhesives Dymax offers specially formulated LED light-curable adhesives for use with Dymax LED UV/Visible light-curing systems. The adhesives range from fast to ultra-fast cure speeds in order to accommodate specific electronic assembly needs. UV Light-Curable Adhesives, Coatings, and Encapsulants for Electronic Assembly 9
