HumiSeal 1A34

HumiSeal 1A34 Description

• HumiSeal 1A34 is a single component, fast curing polyurethane conformal coating.
• It offers easy application and handling and fluoresces under UV light for ease of inspection.
• HumiSeal 1A34 coating is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2002/95/EC compliant.

Application of HumiSeal 1A34

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 1A34 with HumiSeal Thinner 521 or 521EU 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 521 or 521EU.
• Viscosity in the dip tank should be checked regularly using a simple measuring device such as a Zahn or Ford viscosity cup.

Spraying

• HumiSeal 1A34 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 the operator.
• The addition of HumiSeal Thinner 521 or 521EU 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.
• The recommended ratio of HumiSeal 1A34 to HumiSeal® Thinner 521 or 521EU is 1:1 by volume however the ratio may need to be adjusted to obtain a uniform coating.

Brushing

• HumiSeal 1A34 may be brushed with a small addition of HumiSeal Thinner 521 or 521EU.
• Uniformity of the film depends on component density and operator's technique.

HumiSeal 1A34 Application notes

Storage

• HumiSeal products may be stored at temperatures of 0 to 35°C.
• HumiSeal 1A34 should be stored away sunlight and excessive heat, in tightly closed containers.
• If coatings are partially used, the container should be purged with dry nitrogen prior to resealing.
• Prior to use, allow the product to equilibrate for 24 hours at a room temperature of 18 to 32°C.

Caution

Application of HumiSeal Conformal Coatings should be carried out in accordance with local and National Health and Safety regulations.

• 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.
