HumiSeal UV40-250 is a high quality acrylated polyurethane conformal coating. This engineered conformal coating is UV curable and it becomes tack-free after exposure to light. HumiSeal UV40-250 UV Curable Conformal Coating is IPC-CC-830, RoHS Directive 2002/95/EC compliant and is recognized under the UL File Number E105698.
HumiSeal UV40-250 is a low viscosity, one part, UV curable, acrylated polyurethane conformal coating. This material has a secondary moisture cure process that will begin to cure unexposed areas of the coating within the following 2 to 3 days at ambient conditions. When cured, it possesses excellent surface hardness, exceptional chemical resistance, resistance to moisture and good flexibility. Because of the toughened film that provides excellent chemical and environmental resistance, HumiSeal UV40-250 is more difficult to remove compared to many other conformal coatings. Once applied, this material can be inspected because the coating fluoresces under UV light.
HumiSeal UV40-250 UV Curable Conformal coating can be applied using dry inert gas so it will prevent premature secondary cure to occur. It is extremely important t
o spray in an area with good ventilation so that vapors and mists are carried away from the person dispensing. The Shelf life of this material is 12 months in room temperature when it is stored in a tightly closed opaque container. It is extremely essential for the product to be exposed to direct sunlight or full spectrum fluorescent lighting.
The thermal shock, 500 cycles per MIL-I-460-58C is -65 to 125 degrees Celsius. HumiSeal UV40-250 has a UL 94 V-0 rating; it has met the specifications of not burning 10 seconds or longer after a flaming combustion. It is important for the substrate to be extremely clean for the successful application of this material. Contamination under the coating may cause problems which will lead to assembly failures. Once the application of HumiSeal UV40-250 is complete, it is recommended to use a solvent base, non-alcohol thinner to clean uncured coating and to flush out the equipment.
HumiSeal UV40-250 is formulated with a high quality acrylated polyurethane material. HumiSeal, a subdivision of Chase Electronics, is a worldwide leader in providing innovative products using advanced engineering and over 50 years of producing a variety of high performance conformal coating. HumiSeal UV40-250 UV Curable Conformal Coating is an engineered conformal coating with the capabilities to guard and protect electronic assemblies from thermal shock and weathering.
