Carboline Company Introduces Chemical-Resistant Tank Lining

Carboline Company, St. Louis, Mo., has announced the release of Plasite 4550 HT, a highly chemical-resistant reinforced epoxy novolac tank lining, created to simplify and foster a quality installation.

Plasite 4550 HT is a heated plural component novolac-epoxy lining. Its lack of amine blush simplifies holiday testing, spot repairs and unnecessary delays, the company said.

“Plasite 4550 HT has a combination of features that result in higher quality lining installations: smooth application, wide acceptable thickness range, positive curing in cold conditions and a long recoat/touch-up window,” said Mary Roley, technical director-innovation for Carboline. “In comparison to many high performance linings, Plasite 4550 HT is blush resistant, which is particularly important when applying in cold conditions.”

The lining can be easily sprayed in a smooth, uniform film from 12 mils to 40 mils in one coat for maximum quality and durability. It continues to cure at 20 degrees F and can be placed into service the next day in normal temperatures.

“We saw a need in the market to provide the customer with a one-coat, high-build epoxy novolac lining formulated to protect tanks and cargo in a variety of services,” said Doug Moore, director-global product line. “Plasite 4550 HT is the next generation of our popular Plasite 4550 product line. Plasite 4550 HT fits in markets currently using Plasite 4550. In addition, it offers improved temperature performance and better cathodic disbondment resistance.”

Based in St. Louis, Mo., and founded in 1947, Carboline Company produces performance coatings, linings and fireproofing products in more than 20 manufacturing facilities around the world.
