It is known that we need glue to stick makeup brush heads, ferrule and handle during brush production. There are various glues in the market, some are good but expensive, and some are cheap but with bad quality. If the glue is not so good, the brush head may fall apart from the handle under slight pull force.
For makeup brushes, the most two common glues are hot melt glue and AB glue. Hot melt glue can dry very quickly but not so strong, so if you pull the brush strongly, it will fall apart. But if not pull it, it will not fall apart. Hot melt glue is usually used on samples and low grade quality makeup brushes. AB glue is extremely strong; the brushes will not fall apart no matter how you pull it. AB glue is usually used on high grade makeup brushes or low grade brushes if customers have such requirement.
Some may ask why not use AB glue on all brushes. Because AB glue need so long time to dry up, few Chinese makeup brush manufacturer will use AB glue on samples or low grade brushes unless upon customers’ requirements. The hot melt glue only needs little time to dry up while AB glue needs more than 4 hours. Therefore, if the delivery time is urgent, some manufacturers will use hot melt glue on the brushes.
For us who specialize in high grade makeup brushes, we always use AB glue on batch shipment. Sometimes we use hot melt glue on samples if customers require samples urgently. Therefore, some customers may find that our samples may fall apart when they strongly pull the brushes, so they thought our brush quality are not good at all. In fact, we always use AB glue during batch production, so the brushes will never fall apart. It is not really the quality problem. Anyway, to avoid of such misunderstanding, we will use AB glue on all brushes even if samples in all future orders, so that customers can trust our brush quality.
