Safety Measures and Health Protection

Contains dibenzoyl peroxide. May cause sensitization by skin contact. Keep away from dirt, rust, chemicals, concentrated alkalis, and concentrated acids, accelerators (e.g. heavy metal salts and amines). Wear suitable protective clothing, protective gloves, and goggles / face protection during work.

Storage / Shipping

Keep container tightly closed in a cool, dark place. ACRIFIX CA 0020 must not be stored in a refrigerator or deep freezer, since this causes the active ingredient to crystallize and makes it very difficult to redissolve. Storage temperature: max. 86°F / 30°C, min. 54°F/12°C.

Working Instructions

It 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. However, it can also be dosed according to mass using commercially available laboratory scales.

The required amount of hardener at room temperature (64-77°F/18-25°C) for ACRIFIX 2R 0190 and ACRIFIX 2R 0195 SBA 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, ACRYLITE® 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. Since this type of blade is not commercially available, it must be made by the operator from approximately ½ inch thick stainless steel.

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.
