Why are sec-butyl acetate prices rising while downstream buying stays thin?
Sec-butyl acetate quotes have been climbing alongside xylene, yet terminal transactions show no volume growth. Downstream users are restocking only for immediate needs rather than building inventory, a classic price-up, volume-down signal. The squeeze runs through the whole chain: midstream resin and emulsion makers face feedstock at 70-85% of cost and must pass increases downstream, but coatings, appliance and auto-parts buyers resist, threatening to switch suppliers. If this divergence persists, the rally could break at some link, forcing midstream destocking and undercutting upstream pricing power.
