Product Specifications: PC2041AB
Tough-Seal 41 is a UL 94 V-0 LISTED, tough and durable fast gelling Potting Compound and Sealant with excellent Thermal Cycling Stability. This UL APPROVED, medium viscosity material is self-leveling and flows like chocolate syrup around electrical components to ensure complete coverage of your entire PCB or electronic assembly. (UL File#: QMFZ2.E135297)
Tough-Seal 41 has a faster 10-20 minute working time and a Shore Hardness of 65A, which is similar to the hardness of a car tire. Tough-Seal 41 reaches 94% of its full hardness after an overnight cure or with a heat cure of 1 hour at 80°C (176°F). Tough-Seal does not exotherm or shrink during curing, therefore there is no embedment stress induced on the electronic components that could cause damage and failure of the PCB or electronic assemblies. Sensitive electronics can be potted safely with low embedment stress Tough-Seal.
With a high elongation of 200% when fully cured, Tough-Seal 41 maintains exceptional flexibility and thermal cycling stability from –40°C to 100°C (-40°F to 212°F) without pulling back, wilting, or cracking. This ensures a tough seal that will stop moisture or other contaminants from damaging sensitive PCB’s and electronics.
Tough-Seal has very aggressive adhesion to aluminum, making it a perfect choice for potting aluminum housings in LED lighting applications. Tough-seal bonds extremely well with most polymers. For housing and wire insulation materials that are exceptionally difficult to bond to, we offer our KEY PR1200 PRIMER, an aggressive adhesive promoter that is simple to use.
