DEGACRYL® SG for Cyanoacrylate Adhesives

DEGACRYL® SG – High‑Performance Rheology Modifiers for Cyanoacrylate Adhesives

DEGACRYL® SG is Evonik’s portfolio of PMMA bead polymers designed specifically for precise rheology modification in cyanoacrylate (CA) adhesives. The products deliver reliable thickening efficiency, high purity, and consistent processing performance - ideal for formulators developing super glues across a wide viscosity spectrum.

Key Benefits of DEGACRYL® SG

High purity & low residual contents for stable curing and minimal side reactions
Excellent thickening efficiency even at low treat levels
No yellowing & high transparency for visually clear formulations
Fast dissolution at low temperatures to simplify processing
Narrow bead size distribution for consistent quality and predictable viscosity control

Rheology Modification for Cyanoacrylate Adhesives

Cyanoacrylate adhesives are single‑component systems that cure rapidly - typically within one to three minutes - upon contact with ambient moisture. They are used in numerous applications and must be available in viscosities ranging from very low to highly gel‑like.

DEGACRYL® SG polymers serve as high‑performance thickeners that allow formulators to adjust viscosity precisely to the desired level. Their low residual peroxide and moisture content help ensure strong bonding performance, high storage stability, and long shelf life.
