HumiSeal is a division of Chase Corporation and produces conformal coatings from all chemistries, including acrylics, urethanes and silicones, both water based and UV curable. This represents the largest product range and the widest choice of qualified products available. HumiSeal are always at the forefront of conformal coating innovation and product development. This means that HumiSeal can meet all your requirements while constantly striving to stay one step ahead as your business develops.
As well as conformal coating materials, HumiSeal also produces Adhesives, Encapsulation and Thermal Management materials.
HumiSeal ACRYLIC
Acrylic conformal coatings are perhaps the most popular of all conformal coating materials as they are easy to apply and remove, with a wide process window for use. Acrylic coatings dry rapidly, are fungus resistant and provide long pot life. Additionally, acrylic materials produce little or no heat during the curing process, eliminating potential damage to heat sensitive components. The coatings possess low shrinkage, provide significant humidity resistance and exhibit low glass transition temperatures.
HumiSeal POLYURETHANE
Polyurethane coatings are available in either single or two-component formulations. Both options provide excellent humidity resistance and far greater chemical resistance than acrylic coatings. Single component polyurethanes, while easy-to-apply and enjoy long pot life, sometimes require long curing regiments to achieve a full or optimum cure. In some instances, the cure cycle can be accelerated with the application of heat.
HumiSeal UV
HumiSeal's UV curable conformal coatings represent an exciting innovation that provides superior performance. When combined with extremely fast curing, allows for short cycle times and maximum production speeds. These products can be sprayed using traditional automated spray equipment with the relatively simple addition of a small-footprint UV light curing unit.
HumiSeal Synthetic Rubber
HumiSeal’s Synthetic Rubber products are unique formulations that may enable the user to achieve specific protection / environmental goals not offered by “traditional” coatings. Synthetic Rubber materials are characterized by extremely low glass transition temperatures, resulting in stable modulus over a wide temperature range and extreme flexibility. Synthetic Rubbers have the least moisture permeability of all resins currently available. These products do not necessarily represent our complete Synthetic Rubber range.
HumiSeal Silicones
Silicone conformal coatings are most widely used in high-temperature environments due to their innate ability to withstand prolonged exposure to higher temperatures than most other conformal coating chemistries. This attribute has made them the primary choice for under hood automotive applications. They are also capable of being applied in thicker films making them useful as a vibration dampening/isolation tool if the coated assembly is to be placed in a high vibration environment.
HumiSeal WATER-BASED
Water-based conformal coatings, by their very nature, are extremely safe, low odor, low VOC products, developed to enable customers to meet the ever-stricter emissions targets, not to mention the various health and safety requirements. It enables enormous reductions in VOC emissions, especially in the automotive sector. These products are based upon the standard chemistries of Acrylic, and Polyurethane, offering the closest match in protective performance to the existing solvent-based conformal coating range.

Resin Designs ® connector seal grommets and sealing strips provide sealing and corrosion protection for indoor and outdoor equipment, including connectors and electrical components. The material is cold-applied like conventional tapes and grommets or gaskets, yet it has sealing capabilities similar to high-performance potting compounds and is superior in conformability to traditional elastomeric gaskets.
With the increase in processing power, charging wattages and the trend toward smaller, more compact electronic modules, transfer of thermal energy to heat sinks, cooled chassis and other safe locations is essential in maintaining component temperatures within operating specification limits. Resin Designs’ family of thermal interface pads provide superior performance with a variety of thermal pad constructions.
Long-term, reliable protection of sensitive circuits and components is important in today’s delicate and demanding electronics applications. Resin Designs shielding gaskets and Resin Designs gel rope gaskets are designed to deliver by providing shielding and effective grounding of high energy electromagnetic interference (EMI). Resin Designs conductive gaskets provide dependable, cost-effective corrosion protection for aircraft skin and antennas.
Thermal gels and encapsulants offer the most flexibility in formulating to a flowable or non-flow product that fully cures to soft gel or firm elastomer for long term stability in thermal cycling. ThermoSink can be used as a TIM between component and heat sink, or assemblies can be encapsulated for optimum thermal management. Most are offered in a two-component 1:1 mix ratio package for automated meter-mix and dispensing.
