The stabilizer is a component that helps the adhesive to store and maintain the stability of the adhesive during use. If the adhesive used for a long time in high temperature conditions (such as summer), the bond strength will decline, or even completely destroyed, in order to improve the thermal oxidation performance of the adhesive, the join and transition metal organic compounds to form stable complexes turnover, reduced transition metal ions on the catalytic activity of organic peroxides, improve its thermal aging properties. Stabilizer itself is relatively stable, because of its own performance, but also improve the stability of the main resin glue. Commonly used stabilizers are: phenols, aromatic amines, secondary amines, etc.
In the selection of stabilizers must be careful to read the instructions, or reference manual, or can not reach the expected effect, such as quinoline stabilizer can significantly improve the phenolic NBR rubber stick agent (BK-32-250) on heat aging properties, but another phenolic NBR rubber stick agent (ACA-483). No effect, so best when cooked with glue to the manufacturer instructions, or consultation, to avoid the mismatch.
