There are many problems to solve when formulating adhesives. Firstly, the amount of money an adhesive company has to invest in vital research is always limited. Then raw material costs get too high, but users may move to rival products if a company passes those costs on. Increasing customer demands push companies to formulate new products, while at the same time they must often adapt to new restrictions on the raw materials they use. It's fair to say that, as they'll be asked to solve all of these problems, pressure on adhesive formulators comes from all sides. So what options are available on a limited budget?
