an alcohol-based cold dipping liquid in low viscosity for hardening the surfaces of investment models when using gel-duplicating material (AWAIGEL). AWAIDIP penetrates well into the surface of the duplicate model, it becomes hard and smooth and improves the adhesion of waxes when modelling. 1 literan alcohol-based cold dipping liquid in low viscosity for hardening the surfaces of investment models when using gel-duplicating material (AWAIGEL).
