Description
CHT QLE 1050SB is a self-bonding, one-part silicone encapsulant for conformal coating and cloth coating applications where a single-component process is preferred. The product is a 100 percent solids, addition cure coating that cures with heat and bonds to a variety of substrates. Its clear to light brown appearance and low-viscosity body make it useful when the coating needs to flow over board features or fabric texture before cure.
Where This Encapsulant Fits
QLE 1050SB fits printed circuit board protection, flexible electronic assemblies, and coated fabric work where adhesion is a central requirement. CHT lists the grade as self-bonding, which helps distinguish it from standard one-part coating grades that may need different surface preparation or primer decisions. It is also transparent enough for pigmentation, so shops can use it where visual identification or color matching is part of the process. The current product data identifies a 30 Shore A cured hardness, 500 cps viscosity, heat cure, and a 204 degrees C maximum working temperature listing.
Use this grade where the approved process calls for QLE 1050SB specifically. The suffix matters because the self-bonding behavior is part of the product identity. Substituting a non-self-bonding grade can change adhesion, inspection, and rework results even when the base silicone family looks similar.
How QLE 1050SB Supports Conformal Coating
Prepare the board, housing, or fabric by removing dust, oils, release residues, and other contamination before application. Mask connectors and contact areas that must remain uncoated. Apply a controlled film, allow the material to wet the surface, then cure under the documented heat schedule. Since the material is one-part, there is no mix ratio to manage, but storage temperature, age, film thickness, and heat exposure still influence cure quality.
