The ergo.® 4900 accelerator is usually applied to one side, seldom to both sides, at least 2 minutes before the adhesive. It must evaporate fully before the adhesive is applied. It accelerates the curing of anaerobic adhesives and is recommended whenever actual curing within seconds is required, or in presence of inactive materials or gaps too wide for normal curing.
In addition, blobs of excess adhesive in contact with the air can be fully cured by spraying them with ergo.® 4900.
