HumiSeal 2C51 is a two component high strength, fast curing silicone encapsulating gel supplied as Parts A and B, suitable for general printed circuit board applications. HumiSeal 2C51 is characterized by room temperature cure and low viscosity for ease of application and contains UV tracer for ease of inspection. The two components of HumiSeal 2C51 are blue and yellow and turn green when mixed. HumiSeal 2C51 is RoHS Directive 2011/65/EC compliant.
HumiSeal 2C51 conformal coating is:
- silicone based
- fluoresces under UV light
- 2 component chemical cure
- high solids
HumiSeal 2C51 conformal coating has:
- No VOCs or solvent
- low toxicity
- excellent environmental resistance and moisture resistance
- RoHS directive 2015/863/EU
Application of 2C51 Silicone Conformal Coating
Cleanliness of the substrate is of extreme importance for the successful application of HumiSeal 2C51. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Contamination under the coating could cause problems that may lead to assembly failures. Mixing ratio of Part A to Part B is 1:1 by volume (or weight). Prior to application, HumiSeal 2C51 Parts A and B should be thoroughly mixed until a homogenous blend is achieved. Vigorous mixing is not recommended as entraps air pockets into mix.
