Product Overview
This is the new formulation of SciGrip Weld-On #4, reformulated to be free from DCM (dichloromethane) and TCE (trichloroethylene).
Weld-On 4 is a blush-resistant cement for bonding acrylic (poly-methyl methacrylate) to itself. It is a water-thin cement formulated to develop clear bond within minutes with a longer time full bond strength than Weld-On 3. It is less likely to leave white marks (commonly called blushing) with significant and increased strength reached over several hours. 1-2 minutes of working time, 3 minute fixture time and 80% strength at 72 hours. If less time is needed consider Weld-On 3.
SciGrip Weld-On #4 is used extensively in sign fabrication. Strong butt joints are made with flat sheets by using the soak method for such applications as cementing letters to acrylic panels. Butyrate trim-capping of acrylics is another highly recommended use for SciGrip Weld-On #3. It is also widely used in the POP industry (e.g. display), and in the fabrication and bonding of plastic containers, housewares, bottles and many other applications using the capillary method.
