How do I remove HumiSeal 1B31?
According to the Humiseal product spec sheet, “HumiSeal 1B31 is a fast air drying, single component, acrylic coating that provides excellent moisture and environmental protection for printed circuit assemblies.” Acrylics are best removed with the Lead-Free Flux Remover – PowerClean™ (#MCC-PW210A) or the Heavy Duty Flux …
What is HumiSeal coating?
HumiSeal Products are conformal coatings which are designed to prevent corrosion and degradation of electronic assemblies in circuit boards and automotive electronics control components. HumiSeal Products are manufactured by Chase Electronic Coatings, an operating division of Chase Corporation.
How do you apply Humiseal?
Humiseal 1B31 can be applied three ways: spray, dip, or brush. The method of application will depend on the complexity of the masking involved, project volume, and costs of each method. Spray application can be done via hand-spray, aerosol can, or by robotics.
Will acetone remove conformal coating?
MEK or acetone will work. Be sure you have a good ventilation system above for fumes.
What is HumiSeal used for?
HumiSeal materials are used for the protection of electronic and industrial devices against humidity, moisture, surface contaminants, mechanical and thermal stresses, as well as UV and chemical exposure.
Is conformal coating conductive when wet?
No, conformal coatings are non-conductive, or insulative. To do that properly, a coating must have electrically insulating properties with as high of a dielectric withstand voltage (or strength) as possible.
How long does conformal coating take to dry?
To cure the conformal coating Full cure can be achieved in 20 minutes or less by using an infrared lamp or in convection oven at 65 °C [149 °F]. At room temperature, the coat dries to the touch in 7 minutes. And full cure takes about 48 hours.
What dissolves conformal coating?
Dow Corning and other companies produce very popular conformal coatings based on silicones. They offer great protection while being light, durable and easy to rework. Almost without exception, silicone coatings may be removed by either the VOC-Free Flux Remover — UltraClean™ or the No-Clean Flux Remover – VeriClean™.
How is the humiseal 1b73 conformal coating applied?
HumiSeal 1B73 is a one component, acrylic conformal coating that can be applied by dipping, spraying or brushing on. This high quality conformal coating is fast drying and exhibits exceptional flexibility and electrical properties. It will fluoresce under UV light allowing easy inspection and reparability.
How long does it take for humiseal 1b73 to cure?
This high quality conformal coating has a cure time of 24 hours at room temperature or two hours at 76 degrees Celsius. HumiSeal 1B73 will reach its optimum properti es within 7 days of when it is first applied.
What is the ratio of humiseal 1b73 to thinner 73?
The recommended ratio of HumiSeal 1B73 to HumiSeal Thinner 73 is 1:1 by volume; however, the ratio may need to be adjusted to obtain a uniform coating. HumiSeal 1B73 may be brushed with a small addition of HumiSeal Thinner 73. Uniformity of the film depends on the component density and operator technique.
What’s the best temperature to store humiseal 1b73?
HumiSeal 1B73 is extremely flammable, so it should be stored in its original container away from excessive heat or cold. The recommended storage temperature of this product is 0 to 35 degrees Celsius. Before application, it is essential to allow the coating to equilibrate at a room temperature of 18 to 32 degrees Celsius.
