HumiSeal UVA300 Product Family

HumiSeal UVA300 Product Family Description

1. HumiSeal UVA300 Product Family coatings are one-part, high solids, dual-cure acrylated polyurethane conformal coatings possessing LED cure capability.
2. LED cure technology benefits having lower energy consumption, reduced temperatures, no ozone or UV-C generation and increased equipment lifetime.
3. HumiSeal UVA300 Product Family has been formulated with the same base ingredients in different ratios of monomer/oligomer to alter the viscosity of the blends. The HumiSeal UVA300 Product Family has been developed to have the following characteristics.

• Tack free cure with LED UV light at 385nm or 395nm
• Different viscosity ranges available for selective coating equipment (see below).
• Application possible at elevated temperatures to give increased process stability and reduced applicator pressure.
• Secondary cure mechanism that will fully cure any unexposed areas of the coating within 7 days at ambient conditions
• Fluoresce under UV light to allow coating inspection and can be applied by all selective coating equipment.
• High flexibility compared with other UV curable conformal coatings, giving improved adhesion and performance in thermal cycling tests.
• Excellent chemical and moisture resistance.

Application of HumiSeal UVA300 Product Family

Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue, ‘no clean’ assembly materials.

Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level. Please contact Hicotech for additional information.

Spraying

• The air source used for spraying must be dry (a dry inert gas is highly recommended) to prevent premature curing via the secondary cure mechanism.
• The spraying should be done with adequate ventilation so that the vapor and mist are carried away the operator.

Brushing

• HumiSeal UVA300 Product Family may be applied by brush for rework or touch up only.
• Brush must be cleaned with solvent promptly after use.

Clean Up

• To flush equipment and clean uncured HumiSeal UVA300 Product Family, non-alcohol based solvents should be used.
• HumiSeal Thinner 521/Thinner 521EU is recommended.

Rework

• HumiSeal UVA300 Product Family are highly cross-linked UV cured coatings.
• The cured film has a high degree of environmental and chemical resistance and will be more difficult to remove than traditional conformal coatings.
• Thermal displacement and mechanical abrasion are suitable options for rework of HumiSeal UVA300 Product Family.

Storage

• HumiSeal UVA300 Product Family are photosensitive.
• The product should not be exposed to direct sunlight or full spectrum fluorescent lighting.
• Material should be stored away excessive heat, in tightly closed opaque containers at 0 to 25°C to ensure maximum shelf life is achieved.
• Prior to use, allow the product to equilibrate for 24 hours at room temperature.
• UVA300 are moisture curing coatings and care should be taken to protect process vessels and partial containers moisture.
• Partial containers must be purged with a dry, inert gas such as dry air, nitrogen or argon before closure, otherwise premature polymerization by atmospheric moisture will occur.

Caution

• Application of HumiSeal Conformal Coatings should be carried out in accordance with local and National Health and Safety regulations.
• Use only in well-ventilated areas to avoid inhalation of vapours or spray. Avoid contact with skin and eye.
