Air Products & Chemicals Inc., Allentown, said it is raising prices for the fifth time in less than seven months on lines of its surfactants.

The increase, effective June 15, is for up to 10 cents a pound.

Although the company did not give a reason for the latest increase, it cited rising raw-material costs in the previous announcements.

Surfactants are wetting agents used in paints, coatings, inks and adhesives.    - Paul Schweizer
