Question 1

What makes DAP-15 suitable for structural adhesive applications compared with silicone defoamers?

Accepted Answer

DAP-15 is a 100% active, silicone-free polyol defoamer. Silicone-based alternatives can migrate to bond interfaces and reduce adhesive strength; DAP-15 eliminates this risk while effectively suppressing voids and bubbles in one- and two-component PU and acrylic structural adhesives.

Question 2

How should DAP-15 be incorporated into a two-component polyurethane adhesive system?

Accepted Answer

Add DAP-15 to the polyol (B-component) at 0.1–0.5% under low-shear mixing before combining with the isocyanate component. Pre-mixing into the polyol ensures homogeneous distribution and avoids any localised incompatibility at the point of addition.

Question 3

Is DAP-15 appropriate for food-contact packaging adhesive applications?

Accepted Answer

DAP-15 is REACH-compliant. For food-contact end uses, formulators must independently verify compliance with applicable regional regulations — such as EU Regulation No. 10/2011 or FDA 21 CFR — based on the final formulation composition and intended contact conditions.
