Crystic Crestomer 1196PA Obtains RINA Approval

07 August 2009

RINA has approved Crystic Crestomer 1196PA for use as a structural adhesive in sandwich structures for leisure craft deck and hull construction.

Laminate test pieces bonded with Crystic Crestomer 1196PA underwent a flatwise tensile test (to ASTM D 1623) and a sandwich shear test (to ASTM C 273). The RINA strength requirements were satisfied, even after the test pieces had undergone two cycles of laboratory ageing under ASTM D 1183 Type “D” test conditions

Each ageing cycle takes a week to complete, during which the bonded test pieces are exposed to extremes of temperature from +71°C to -57°C, different humidity conditions and prolonged periods immersed in salt water.

Giuseppe Dell’Anno, the R & D Applications Engineer at Scott Bader who led the RINA test project commented: “It was a very tough test programme; gaining RINA approval for 1196PA provides FRP boat builders with further assurance of the high quality and guaranteed performance characteristics of Crestomers for marine structural bonding.”

In addition to the RINA approval, Crestomer 1196PA and rest of the Crestomer range has Lloyds approval; most grades also have DNV class 1 approval
