MADISON HEIGHTS, Mich. Henkel has announced North American price increases on industrial products for the automotive and metals industries. The company said the increases are a result of ongoing escalation of raw material and energy costs. Product categories that will be affected are adhesives, sealants, lubricants and surface treatment products. The first increases were implemented in January, and the remaining will go into effect throughout 2012 based on product type. Increases will vary by chemical platforms, and customers will be notified directly and in advance of any pricing changes, Henkel says. The company noted that it felt "compelled" to take this step in order to further ensure delivery of the same high-quality product and service standards expected by its customers.
