HumiSeal 1B66

HumiSeal 1B66  Description

• HumiSeal 1B66 is a fast drying, single component, acrylic conformal coating that provides excellent moisture and environmental protection for printed circuit assemblies.
• HumiSeal 1B66 demonstrates outstanding flexibility and is easily repaired.
• This coating is RoHS Directive 2002/95/EC compliant.

Application of HumiSeal 1B66

Cleanliness of the substrate is of extreme importance for the successful application of a conformal coating. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Contamination under the coating could cause problems that may lead to assembly failures.

Dipping

• Depending on the complexity, density and configuration of components on the assembly, it may be necessary to reduce the viscosity of HumiSeal 1B66 with HumiSeal Thinner 503 in order to obtain a uniform film.
• Once optimum viscosity is determined, a controlled rate of immersion and withdrawal (5-15 cm/min) will further ensure even deposition of the coating and ultimately a uniform film.
• During the application, evaporation of solvent causes an increase in viscosity that should be adjusted by adding small amounts of HumiSeal Thinner 503.
• Viscosity in the dip tank should be checked regularly, using a simple measuring device such as a Zahn or Ford viscosity cup.

Spraying

• Spraying HumiSeal 1B66 can be sprayed using conventional spraying equipment.
• Spraying should be done in an environment with adequate ventilation so that the vapour and mist are carried away from the operator.
• The addition of HumiSeal Thinner 521 is necessary to ensure a uniform spray pattern resulting in pinhole-free film.
• The amount of thinner and spray pressure will depend on the specific type of spray equipment used and operator technique.

Brushing

• HumiSeal 1B66 may be brushed with a small addition of HumiSeal Thinner 503.
• Uniformity of the film depends on component density and operator's technique.

Storage

HumiSeal 1B66 should be stored away from excessive heat or cold, in tightly closed containers. HumiSeal products may be stored at temperatures of 0 to 35°C. Prior to use, allow the product to equilibrate for 24 hours at a room temperature of 18 to 32°C.

Application notes

• Application of HumiSeal Conformal Coatings should be carried out in accordance with local and National Health and Safety regulations.
• The recommended ratio of HumiSeal 1B66 to HumiSeal Thinner 521 is 1:1 by volume.
• The solvents in HumiSeal Conformal Coatings are flammable. Material should not be used in presence of open flame or sparks. Use only in well-ventilated areas to avoid inhalation of vapours or spray. Avoid contact with skin and eyes.
