Use of Adhesive:
Apply a thin film to one of the mating surfaces to be bonded. Applying light pressure, press the
two parts together and hold in position with masking tape until the adhesive has cured. Only
use a thin film of adhesive, excessive amounts do not provide any additional strength and add
unnecessary weight. Remove any paint from surfaces to be glued, as this could impair the
strength of the bond. Always check the fit and alignment of parts to be glued prior to the
application of adhesive.
Please Note:
“EPOFLEXY” is a very tough and durable material perfect for the manufacture of model aircraft.
When using screwed fixings with “EPOFLEXY” components it is important to tighten the screws
sufficiently to provide a firm fixing.
Excess tightening could result in the foam material becoming compressed, possibly damaging or
distorting the part. Take care to ensure that all screws are tightened sufficiently to provide a firm
fixing, but do-not over tighten. We recommend that all fixings are checked regularly for security
and safety purposes.
