ACRIFIX® MO 2080 is used to slow down the polymerization reaction of our reactive cements. It moderates the heat generated during the curing process and resolves bubbles and crazing issues. When used with a two-component polymerization cement such as ACRIFIX® 2R 0190 or ACRIFIX® 2R 0195, cement joints become practically invisible.
Two-component cement should be used when strength, resistance to environmental conditions, and high optical appearance is required. They also ﬁll better and impose fewer demands on the accuracy of ﬁt between the parts.
Two-component cement consists of polymers dissolved in monomers (Part A) which cure when a catalyst or hardener (Part B) is added. They are also referred to as two-part cement. The cure, or hardening of the cement mixture, is brought about by a chemical reaction. As a result of the chemical reaction the cement mixture shrinks and heats up as it cures. This can often result in the formation of bubbles or “pull back” of the cement from the edges of the joint. The proprietary formulation in ACRIFIX MO 2080 eliminates or reduces these defects.

The following equipment and conditions should be considered when using polymerizable cement:
Mixing Procedure for ACRIFIX MO 2080 acrylic cement modiﬁer
Follow instructions for the mixing ratios of the two-part cement. For 100 grams of ACRIFIX® 2R 0190 or ACRIFIX® 2R 0195 (Part A) and 5 grams of ACRIFIX® CA 0020 (Part B) add 0.12 grams (6 drops) of ACRIFIX® MO 2080. Adjust ratio for different size batches (example: Use 3 drops with 50 grams of “Part A” and 2.5 grams of “Part B”).
In some cases a product like ACRIFIX® TC 0030 Thinner and Cleaner can be used to reduce the viscosity of the cement mixture to allow the material to ﬂow into the joint better. The recommended amount of thinner is up to 10% by weight of the mixture. Fully stir the mixture for 1 to 2 minutes.
The mixture should be degassed using one of the following techniques before applying adhesive to the joint.
When the two-part cement is ready, apply the mixture to the joint. Wait for the material to be fully cured before attempting to move the acrylic. Premature movement of the acrylic can cause quality issues. ACRIFIX® MO 2080 may double the typical pot life from 20 minutes to 40 minutes.
