Development of improved H.E. adhesives systems. Quarterly report, January, February, March 1964
Optimum mix of allyl glycidyl ether, needed as a thinner for Aerobond H-7, appears to be about 10 pph AGE which reduces viscosity to 165 cps. This reduces torsional shear strength to 930 in-lbs/in{sup 2} versus 1616 in-lbs/in{sup 2} in tests this quarter and values as low as 520 in-lbs/in{sup 2} reported previously. Water permeability was measured again for Adiprene, Perm-A-Lon and Estane; Aerobond H-7 was also measured using a filter paper backing material. The value for Estane was lower than in previous tests, 0.27 mg/cm{sup 2}/hour versus 1.08 and 1.15 mg/cm{sup 2} hour reported earlier. The disc extrudability test was set up and preliminary data were gathered for three lots of LX-0201 and several tile materials. The experiment to detect deficiencies in Adiprene L-100 as an adhesive for H.E. caused by aging is in its third year. Tensile strength results indicated no deterioration; but shear strength results were questionable. In both cases, breakage occurred in the H.E.
