Name: Evonik Dynasylan Kat 244 Non-toxic metal-based neutral cure silicone catalyst
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan Kat 244 Non-toxic metal-based neutral cure silicone catalyst

Non-toxic, tin-free formulation compliant with stringent global regulatory requirements including REACH and RoHS.
Enables fast, reliable neutral-cure kinetics for acetoxy- and oxime-based silicone sealants without acidic by-products.
Excellent storage stability in formulated systems—minimizes premature gelation and extends shelf life of base pastes.
High catalytic efficiency at low addition levels (typically 0.1–0.5 wt% relative to polymer), reducing formulation cost and VOC impact.
Compatible with common silicone polymers, fillers, and adhesion promoters—supports broad formulation flexibility.

Typical Applications Of Evonik Dynasylan Kat 244 Non-toxic metal-based neutral cure silicone catalyst

Neutral-cure acetoxy silicone sealants for architectural glazing and façade construction.
Oxime-cure silicone RTV adhesives used in automotive assembly and electronics encapsulation.
High-performance silicone sealants for sanitary applications (e.g., kitchens, bathrooms) requiring low odor and non-corrosive cure.
Industrial bonding and sealing formulations where tin-based catalysts are restricted or prohibited.
