Synthetic Rubber 1B59 Sharp Edge Coverage
HumiSeal® 1B59 Sharp Edge Coverage is an air drying, single component, synthetic rubber conformal coating. HumiSeal® 1B59 SEC is formulated to provide increased coverage on component edges, when compared to other similar coatings. HumiSeal® 1B59 SEC is formulated for effective application using atomized spray application methods, although other methods can also be used.
HumiSeal® 1B59 SEC demonstrates the following advantages:
- Excellent coverage of sharp edge components.
- Extremely low moisture vapor permeability.
- Protection against moisture, salt / corrosive environments, and dirt.
- Improved thermal stability compared with other conformal coatings.
- Excellent flexibility putting low stress on components.
- Es fluorescente bajo los rayos UV para facilitar la inspección y se repara fácilmente.

Application of HumiSeal® 1B59 SEC
Conformal coatings can be successfully applied to boards that have been cleaned prior to coating and also to boards assembled using 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 HumiSeal for additional information.
HumiSeal® 1B59 SEC is specifically formulated to shear during application to a viscosity suitable for atomized spray application. No additional dilution is required. HumiSeal® Technical Support should be contacted if any further advice on application methods is required.
Storage
HumiSeal® 1B59 SEC 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 ambient temperature.
Precaución
La aplicación de los revestimientos conformados HumiSeal® debe realizarse de acuerdo con las normativas locales y nacionales de salud y seguridad.
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.
Consult MSDS/SDS prior to use.
