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.
Performance in Super Glue Formulations
DEGACRYL® SG helps formulators achieve:
- High transparency and consistent appearance
- Long storage stability without yellowing
- Strong and reliable bonding performance
- Efficient manufacturing, even at low temperatures, due to excellent dissolution behavior
Why Choose DEGACRYL® SG?
DEGACRYL® SG combines purity, performance, and process efficiency - making it the preferred rheology modifier for cyanoacrylate formulations. With tightly controlled bead quality, predictable thickening behavior, and minimal impact on curing, DEGACRYL® SG enables formulators to create high‑performance, stable, and clear super glues across a wide viscosity range.
