Loctite Engineering Grade products are high performance fluids developed to be highly consistent with extraordinary attributes. Loctite E-3955 FST HH is a high performance, high modulus product which boasts excellent flexural and tensile properties with outstanding flame retardance. E-3955 FST HH displays high HDT, enabling it to be used in harsh environments without deformation or deflection. It passes flammability standards such as UL94 V-0 and AirBus AITM2-0002. E-3955FST HH has been tested in QUV exterior weathering conditions (ASTM G-154-Cycle 1) for 1600 hours with less than a 15% change in flexural properties.
