Description
CHT QLE 1033 is a red, two-part silicone encapsulant for coating fabric, cloth, and flexible assemblies that need a tough elastomeric surface. The grade is listed as a 100 percent solids addition cure material, so the coating builds film without relying on solvent evaporation. A long open time gives operators time to spread, level, and inspect the film before heat cure, which is especially useful on wide fabric sections or parts with corners, seams, and fixture edges.
Where This Encapsulant Fits
QLE 1033 fits industrial coating work where color identification, flexible adhesion, and repeatable cure are more important than a rigid potting mass. The CHT silicone product page lists red color, liquid rheology, 10 to 1 mix ratio by weight, and a 60 minute cure profile at 150 degrees C. Those traits make the grade suitable for controlled coating operations where the material is mixed, applied as a film, and then moved into a heat process after wet inspection. The cured Shore A hardness is published in the low 30s, giving the coating enough softness to move with fabric or cloth while still forming a resilient silicone layer.
Use this grade when the drawing, approved material list, or process route names QLE 1033 specifically. Adjacent QLE coating grades can look similar in a catalog but differ in color, hardness, viscosity, and cure schedule. Keep containers, tools, and batch paperwork organized so the correct A and B sides stay paired through the work cell.
How QLE 1033 Supports Coated Parts
Before coating, confirm substrate cleanliness, target film build, and cure equipment capacity. Apply evenly, avoid trapping bubbles at fabric texture changes, and give the coating time to settle before cure. The long open time can help during setup, but it also means parts need stable staging so the wet film is not disturbed. On repeat production, document mix weight, work time, cure temperature, and inspection criteria so each run matches the approved sample.
