What are hybrid sealants and what are they used for?
Hybrid sealants, often referred to as MS polymer sealants, combine the advantages of silicone and acrylic. They are elastic, have strong adhesion, and are paintable. This makes them particularly suitable for construction, assembly, and repair work where high demands are placed on adhesion and flexibility.
In this category, you will find high-performance hybrid sealants for professional indoor and outdoor applications.
Typical applications for hybrid sealants
Hybrid sealants are versatile and adhere to many materials.
Typical applications:
- Construction and expansion joints
- Assembly and bonding applications
- Connection joints for windows and doors
- Metal, concrete, wood, plastic
- Indoor and outdoor areas
Properties of hybrid sealants
Hybrid sealants offer high technical performance.
Important properties:
- very high adhesive strength
- permanently elastic
- paintable
- weather and UV resistant
- mostly solvent, silicone, and isocyanate-free
Differences between hybrid, silicone, and acrylic
Each sealant type has its optimal area of application:
-
Hybrid sealant: elastic, strong adhesion, paintable – ideal for construction & assembly
-
Silicone: waterproof & highly elastic – ideal for wet areas
-
Acrylic: paintable, for dry indoor areas
Hybrid sealants are particularly the right choice when bonding and sealing need to be combined.
