There are many filter glue manufacturers on the market. In the filter glue industry, because there is no industry-implemented labeling, the quality is also uneven. Products from different manufacturers also have different shelf life labels for glue. Some manufacturers say that their products have a shelf life of6months; The manufacturer claims a shelf life of12months. In fact, for two-component polyurethane filter glue, most manufacturers’ products on the market are marked with 66 months The shelf life, then 1212 months is actually a problem, but it will not be able to achieve the best performance in the later period. What does that mean? Let’s take a look at a set of data with the editor of Weigu.
It can be seen from this set of test data that within the first six months of the glue, the adhesive strength, mixing viscosity, There are almost no major changes in factors such as hardness, dead time, and density. After 6months, these properties of the glue fluctuated significantly. 12months old, the adhesive strength of the glue decreased40 %around, the hardness has also decreased a bit. Therefore, it shows that this type of glue can achieve the best performance of the glue in the first six months of use, and after 6months, The performance of the glue has been reduced, but it can still be used, but it does not reach the optimal performance of the product. Therefore, for this model of glue, whether the shelf life is 6months or 12months, no problem. However, saying6months is a guarantee for the quality of customers’ products, saying12months. In terms of later use, the performance of the glue has declined, but it will not affect the use of the glue too much.
Weigu’s two-component polyurethaneab glue is a white, bubble-free, water-free, room temperature curing Polyurethane adhesive has the characteristics of high bonding strength, good fluidity, fast solidification and no irritating odor. It has excellent stability, anti-aging, and water resistance. It is suitable for bonding, filling, and sealing between metal materials such as plated plates, aluminum plates, and non-passivated stainless steel plates, and non-woven fabrics, filter papers, and other materials. The product is mainly used in Partition, non-partition, FFU, V-type and other medium and high-efficiency filters, dust filter cartridges and other products. The finished product complies with testing standards such as ROHS and REACH.
