Sealentype

Sealentype is a generalized term used to describe a class of sealant materials designed to seal joints and closures while accommodating movement and providing barriers against air, water, dust, and contaminants. The designation does not refer to a single chemical family; instead, Sealentype encompasses formulations based on silicone, polyurethane, acrylic, epoxy, and other polymer matrices. In product catalogs, Sealentype is often used as a category label to group sealants with similar performance goals.

Composition and variants: Sealentype formulations typically rely on one of several polymer bases, such as silicone elastomers, polyurethane elastomers, epoxy resins, or acrylics. Fillers, plasticizers, and coupling agents are added to adjust viscosity, elasticity, cure time, and substrate compatibility. Cure mechanisms vary and can include moisture cure, heat cure, or two-component systems, enabling a range of installation conditions and end-use requirements.

Properties: Common characteristics include strong adhesion to diverse substrates (glass, metal, concrete, ceramic, plastics), flexible or elastic film formation, and resistance to weathering, UV radiation, ozone, and chemicals. Depending on the formulation, Sealentype products may offer different shore hardness, elasticity, and elongation at break, balancing sealing performance with movement tolerance.

Applications: Sealentype materials are used in construction for glazing and joints, in automotive and aerospace for weather sealing, in electronics enclosures, sanitary installations, and infrastructure projects requiring waterproofing and vibration damping.

Standards and safety: Performance is assessed through adhesion, durability, chemical resistance, temperature tolerance, and movement capability tests; safety data sheets cover handling and exposure considerations.
