Humiseal UV500 Curable Conformal Coating

Description HumiSeal UV500

HumiSeal UV500 is a high solids UV dual cure elastomeric acrylate conformal coating. HumiSeal UV500 exhibits excellent flexibility, moisture resistance and electrical insulation properties as well as good chemical resistance.

Benefits when using HumiSeal UV500

1. HumiSeal UV500 has been specifically developed to:
2. Cure tack-free with microwave or arc UV light.
3. Have a secondary cue mechanism that will fully cure any unexposed areas of the coating within 7 days at ambient conditions.
4. Have a higher flexibility compared with other UV curable conformal coatings, giving improved performance in thermal cycling tests.
5. Fluoresce under UV light to allow coating inspection.
6. Be applied by all selective coating equipment.
7. Have excellent chemical and moisture resistance.

Technical when using HumiSeal UV500

Application of HumiSeal UV500

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. 

1. Spraying

HumiSeal UV500 can be applied via standard selective coating equipment or by conventional hand spray equipment. The source air used for spraying must be dry (a dry inert gas (nitrogen or argon) is highly recommended) to prevent premature curing of the secondary cure mechanism. The spraying should be done with adequate ventilation so that the vapor and mist are carried away from the operator.

2. Brushing

HumiSeal UV500 may be applied by brush for rework or touch up only. Brush must be cleaned with solvent promptly after use.

3. Curing

HumiSeal UV500 is a highly crosslinked coating. In order to achieve maximum crosslinking density, the product must be exposed to the correct spectral output.

HumiSeal UV500 Application note 

1. Clean Up

• To flush equipment and clean uncured HumiSeal UV500, non-alcohol based solvents should be used. HumiSeal Thinner 521 or Thinner 521EU is recommended.

2. Rework

• HumiSeal® UV500 is a highly crosslinked UV cured coating.
• 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® UV500.

3. Storage

• It is photosensitive. The product should not be exposed to direct sunlight or full spectrum fluorescent lighting.
• HumiSeal UV500 should be stored cool below 20°C, to maximize shelf life. Prior to use, allow the product to equilibrate for 24 hours at room temperature.
• This is a moisture curing material and care should be taken to protect process vessels and partial containers from 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

It 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 eyes. Consult SDS prior to use.
