Description
CHT Group QLE 1100 is a QLE 1100 coating for PCB conformal coating and cloth coating where a one-part heat-cured silicone elastomer is preferred. The clear to light brown liquid is a 100 percent silicone solids material with fast elevated-temperature cure and good abrasion resistance.
QLE 1100 Coating Benefits
- One-part format removes the need to meter A and B components before coating.
- 100 percent solids silicone chemistry supports controlled film build without solvent reduction.
- Transparent appearance is useful where pigmentation or visual inspection matters.
- Primerless adhesion to many substrates can simplify coating trials on clean surfaces.
- Heat cure schedules support production work that can run elevated-temperature processing.
This coating fits electronics, fabric, and industrial coating workflows that can accommodate heat cure. Apply it to clean surfaces and confirm adhesion on the exact substrate before release. Some surfaces can be difficult to bond to, and galvanized metal may inhibit cure, so a primer or process adjustment may be needed after testing.
Common Applications for QLE 1100 Coating
- Conformal coating on printed circuit boards and electronic assemblies.
- Cloth coating where a one-part silicone layer is preferred.
- Thin protective silicone films on clean industrial substrates.
- Coating trials that need a low-viscosity liquid for controlled application.
- Assemblies exposed to flex, moisture, and elevated service temperature.
Compatible Materials and Process Notes
- Use on clean PCB, fabric, and approved industrial substrates after test coating.
- Confirm cure on any substrate that could inhibit addition-cure silicone chemistry.
- Use heat schedules such as 5 minutes at 200 C or 30 minutes at 150 C when suitable for the part.
- Keep storage temperature and shelf-life limits aligned with the current container label.
