Polyken 939防腐涂层填充胶带

Polyken filler tapes are designed as an underlying filler material prior to the application of Polyken coating systems. The elastomeric formulation is very conformable, making it ideal for filling in transition areas around T's, ells, valves, specials, welded and coupled field joints. The filler tapes maintain flexibility over a wide temperature range and under various conditions encountered in the field. , • Flexible under various field conditions
• Conformable and moldable
• Easy and simple application
• Compatible with Polyken coating
   systems.

Polyken # 939 is a thick mastic-like butyl rubber filler designed to fill and smooth transition areas. The semi-tacky composition remains flexible and is easily molded in place to conform around irregular shapes.
