Humiseal UV40 Gel LED Conformal Coating
The popular Humiseal UV40 conformal coating is now available as a gel. The Uv40 gel by Humiseal was formulated specifically for some large scale LED (light emitting diode) applications including the huge LED displays that are seen in sporting stadiums where a light weight coating was needed. Humiseal UV40 gel is ideal when a light weight hermetically sealed housing is needed for electronic circuitry that will withstand extreme UV exposure, moisture ingress from rain and lightning strikes. The material has been used in the manufacturing of LED Displays carried on 
blimps and hot air balloons. The standard Humiseal UV40 conformal coating is applied with the UV40 gel around sensitive areas of the circuit board to increase the thickness of covering. Offering an application thickness up to 1mm, nearly 10 times the normal thickness of conformal coating.
The gel conformal coating materials by Humiseal including the UV40 gel, provide more control and flexibility allowing materials to be deposited only where required and avoiding more sensitive area’s. As technology becomes increasingly more difficult with requirements to design smaller and more densely populated assemblies, the gel coatings offered by Humiseal including UV40, the acrylic based 1B31 and the urethane based 1A33 are helping manufacturers meet reliability and performance targets for the life of the products. These products also allow customers to deploy damn and fill coating techniques around selected components by building a damn of gel product around a device and then filling with a standard conformal coating.
Humiseal UV40 clear gel is a one part anti-sagging 100 percent solids dual cure acrylated polyurethane conformal coating possessing excellent chemical resistance, surface hardness, flexability and moisture resistance. The material is tack free after exposure to UV light and the secondary moisture cure mechanism will fully cure any exposed area’s of the coating within two to three days at ambient conditions, the secondary cure can be accelerated by baking. For full technical data info please see our UV40 gel TDS .PDF or contact Krayden, Inc. Authorized Distributor at www.krayden.com
Manufactured and available globally, Humiseal’s range of gel products are the result of it’s ongoing work to continuously improve and develop sector-specific products that reflect it’s client’ needs in a real and competitive world.

New Acrylic Adhesive Maxlok
Announcing a new acrylic adhesive with versatile substrate bonding capabilities manufactured by the LORD Corporation. This cutting edge technology allows surfaces to be mated more than once allowing for a more forgiving and user friendly application process. For use in various industries such as; solar, transportation, shipping and construction. The new Maxlok acrylic adhesive comes in three cure speeds using glass bead technology to optimize the bond line thickness. The optional cure speeds offer more flexibility when dealing with seasonal temperatures and optimal dispensing ability.The Maxlok is available in gray to blend more easily with metals and works in a broad range of temperatures (-40 to +300 Fahrenheit).
“This adhesive provides a low-cost alternative with superior performance in applications involving welding, riveting or other traditional mechanical fastening methods, especially in extreme temperature environments subject to high impact or high peel loads.“Maxlok is a premiere metal bonding system with superior performance across various substrates, which provides improved efficiencies and flexibility within customers’ manufacturing processes,” said Carlos Cruz, LORD Market Manager, Product Assembly Adhesives and Coatings, Americas Region. We have already seen great success using this adhesive in armored vehicles, motor coaches and trailers.”
According to Cruz, structural adhesive bonding is an established joining method that is proven in a variety of end-use markets – including more than 50 million cars, trucks, specialty vehicles and boats worldwide. The benefits of structural bonding have been widely touted for decades and are best summarized building a better product, faster, more simply and with less cost. When compared to mechanical fasteners and welding, structural adhesives widely distribute stresses, act as a sealant, reduce noise and vibration, offer excellent durability, help prevent corrosion and maintain the original mill finish quality of the exterior surface of thin panels. Adhesives also offer a lower cost option to traditional joining methods, decrease the margin of error and improve manufacturing processes and final products.
Superior performance has been achieved on multiple substrates, in particular galvanized steel.Intended for use in demanding applications such as transportation, wind and solar energy, shipping, specialty construction and the recreational/specialty vehicle industries, Maxlok has been validated through multiple bond and peel strength tests, outperforming competing products as well as traditional mechanical fastening methods. A flexible and process-friendly solution, Maxlok offers high adhesion strength without the need for a primer, which saves time and money. As compared to competing products, Maxlok offers better environmental performance, salt spray and humidity performance. Further, the acrylic adhesive defies dilute acids, alkalis, solvents, greases, oils, moisture, salt spray and weathering, while providing excellent resistance to UV exposure.
Cost savings can be significant: while welding requires skilled operators, bonding simply requires good operators. For companies interested in switching to adhesives, LORD offers a cost modeling tool that enables users to detail specific applications and requirements in order to determine how much they will save by the transition.
