Description
ACRIFIX® CA 0020 Catalyst is a hardener for polymerization cement based on methyl-methacrylate. This hardener (suggested to add 3 % ~ 6 %) was developed for ACRIFIX® two-part reactive cements. It polymerizes completely upon addition of ACRIFIX® CA 0020.
- Hardener for MMA adhesives
- For use with ACRIFIX® 2-part reactive cements

Working Instructions
ACRIFIX® CA 0020 can be dosed according to volume by means of a graduated pipette, a burette, a disposable syringe or, best of all, by means of a dispenser. Attention: for volume-based dosage with pipettes/ burettes at cool ambient temperatures, please observe any tailings. However, it can also be dosed according to mass using commercially available laboratory scales. The required amount of hardener at room temperature (18 to 25 °C) is 3 %. At lower ambient temperatures and for special adhesive compositions, the required amount of hardener may be up to 6 %.
ACRIFIX® CA 0020 is stirred into the adhesive by hand, using a stirring rod made of glass, PLEXlGLAS® or stainless steel (free from copper!).
If larger quantities of adhesive are used (> 200 g), an electrically or pneumatically operated agitator should be used. Stirring is performed by means of a stainless-steel propeller or, better still, with a stainless-steel stirrer blade (see picture). Since this type of blade is not commercially available, it must be made by the operator from approx. 5 mm thick stainless steel. The stirring period should be approx. 2-3 minutes, the adhesive mix should be free of streaks. Bonded parts can be further treated 3 to 6 hours after curing.
The bonds only acquire their final strength after about 24 hours or after immediate annealing as soon as the adhesive has cured.
Working Instructions
Once the shelf life of ACRIFIX®CA 0020 has expired, the response time of the adhesive can deteriorate significantly.
Safety
Safety Measures and Health Protection
ACRIFIX® CA 0020 Catalyst contains chemicals that can be hazardous if mishandled. Always wear appropriate protective equipment, including gloves, goggles, and face protection when handling the catalyst.
- Personal Protective Equipment (PPE): Use chemical-resistant gloves, protective eyewear, and protective clothing when handling this material.
- Ventilation: Ensure good ventilation in the work area to avoid inhalation of vapors.
- Inhalation Risks: May cause respiratory irritation. Avoid breathing in vapors or fumes. If inhaled, move to fresh air and seek medical attention if symptoms persist.
- Skin Contact: May cause skin irritation. In case of contact, wash the affected area thoroughly with soap and water.
- Eye Contact: May cause eye irritation. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
- Spillage: In case of spillage, contain the spill and absorb with an inert material such as sand. Dispose of waste in accordance with local regulations.
- Storage: Store in a cool, well-ventilated area, away from heat and direct sunlight. Keep the container tightly closed when not in use.
First Aid:
- Inhalation: Remove victim to fresh air and keep at rest in a position comfortable for breathing. Seek medical attention if symptoms occur.
- Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing. Seek medical attention if irritation persists.
- Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention if irritation persists.
- Ingestion: Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.
