Bought this for gluing PLA 3DP parts together, as I've successfully used IPS Weld-on 4 for melting/welding PLA together in the past. This is a bit runnier than I was hoping for, but it seems to hold PLA parts together reasonably well with clamp pressure. I tested this for acrylic (which is the actual intended use), and it works quite well. My only complaint is the tube squirts out way too easily. Packaging has much room for improvement for this product, but the actual glue is good.
