HumiSeal UV40 Product Family

Description HumiSeal UV40 Product Family

HumiSeal UV40 is a single component, high solids, UV curable, acrylated polyurethane conformal coating that possesses excellent chemical resistance, surface hardness, flexibility and moisture resistance.

• The material is tack free after exposure to UV light.
• A secondary moisture cure mechanism will cure unexposed areas of the coating within 2-3 days at ambient conditions.
• The coating fluoresces under UV light to allow for coating inspection and can be applied by selective coating equipment.
• HumiSeal UV40 coating is recognized under UL File Number E105698, and is MIL-I-46058C qualified, and IPC-CC-830 and RoHS Directive 2011/65/EC compliant.

Technical data of HumiSeal UV40 Product Family

Application of HumiSeal UV40 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. 

Spraying

• HumiSeal UV40 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 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 the operator.

Brushing

• HumiSeal UV40 may be applied by brush for rework or touch up only. Brush must be cleaned with solvent promptly after use.
• Curing HumiSeal UV40 is a highly cross linked coating. In order to achieve maximum cross linking density, the product must be exposed to the correct spectral output.
• Humiseal has modelled the performance of UV40 using Arc and Microwave based UV curing equipment.
• Minimum figures should provide a tack free surface.
• The maximum recommendation represents highest tested by Humiseal.
• The cure recommendations may change as curing technology develops.

Clean Up

• To flush equipment and clean uncured HumiSeal UV40, non-alcohol based solvents should be used.
• HumiSeal Thinner 521 or Thinner 521EU is recommended.

Rework

• HumiSeal UV40 is a highly cross linked 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, mechanical abrasion and, where available, HumiSeal Stripper 1100 are suitable options for rework of HumiSeal UV40.

Storage

• HumiSeal UV40 is photosensitive.
• The product should not be exposed to direct sunlight or full spectrum fluorescent lighting.
• HumiSeal UV40 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.
• HumiSeal UV40 is a moisture curing material 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 eyes.
