HumiSeal 1C51 Description
- HumiSeal 1C51 is a single component, VOC-free, fast thermal curing silicone conformal coating.
- The low viscosity and long pot life of HumiSeal 1C51 make it ideal for dipping and spraying.
- It demonstrates excellent flexibility and contains an optical brightener for inspection under black light.
- This coating is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2011/65/EU compliant and recognized under UL File Number E105698.

Application of HumiSeal 1C51
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” 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.
Dipping
- A controlled rate of immersion and withdrawal (5-15 cm/min) will ensure even deposition of the coating and ultimately a uniform film.
Brushing
- HumiSeal 1C51 may be brushed.
- Uniformity of the film depends on component density and operator's technique.
Spraying
- HumiSeal 1C51 can be sprayed using conventional spraying equipment.
- Spray pressure will depend on the specific type of spraying equipment used and operator technique.
- Spraying should be done in an environment with adequate ventilation so that the vapour and mist are carried away the operator.
- The use of thinner is not required or recommended for HumiSeal 1C51.
Curing
- HumiSeal 1C51 is a thermally cured conformal coating.
- The actual curing temperature of HumiSeal 1C51 is dependent upon several parameters such as heat sink characteristics of parts being coated, the type of oven used for curing process, as well as oven loading parameters.
- The cure mechanism for thermally cured silicones like HumiSeal 1C51 may be inhibited by a variety of materials i.e.; amines, acrylates, certain ingredients latex rubber etc.
- It is recommended that process and material compatibility be considered when incorporating HumiSeal 1C51 the production environment.
- Cotton gloves are recommended for operators who will be handling assemblies prior to coating with HumiSeal® 1C51.
HumiSeal 1C51 Application notes
Storage
- HumiSeal 1C51 should be stored at 25°C or below in tightly closed containers away direct sunlight.
- Cold storage of HumiSeal 1C51 (-15°C -to 4°C) will extend its shelf life.
- If the product is stored at cold temperatures, allow the product to equilibrate for 24 hours at room temperature prior to use.
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.
