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.
- 在紫外线下会发出荧光，便于检查，而且容易修复。

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.
