22/ while his are [[underlined]] hydrophobic [[/underlined]] i.e they repeal water instead of attracting it in damp weather as Pollopas does. - Absolutely unimpaired flowing qualities after 6 months at 20°C. - The deterioration is so small as to be undetectable by the usual determinations of flowing qualities. Later on specially at 25°C, the deterioration even after one year does not impair its use for molding altho' flow is less. [[underline]] Question 2 [[/underline]] = What is time of hot curing (polymerisation) A = from 1½ [[strikethrough]] to [[/strikethrough]] for dinner plates or similar thin stuff to 3 minutes for thicker plates of 1 cm. thickness or similar thick articles. - In all cases hot release, except for W.C seats of 1 c.m. thickness or similar thick articles where short cooling is employed. [[underline]] Question 3 [[/underline]] = Do the molds stain? A = No, we use stainless steel or ordinary steel chromeplated. I [[strikethrough]] asked about [[/strikethrough]] W.C. seat and cover 1 c.m. thick is cured in 6 min and cooled in about ½ min [[underline]] Question 4 [[/underline]] = What is its resistance [[underline]] to heat? [[/underline]] A = At 140°C decomposition Safe temp = 100°C. - [[strikethrough]] Molding temperature 140°C [[/strikethrough]] Can be molded at 140°C and (at [[strikethrough]] 4 [[/strikethrough]] 4°C. ??) [[underline]] Question 5. [[/underline]] What is power factor? A = 0.03 (?) expects newer data [[end page]] [[start page]] 23/ [[underline]] Question 6 [[/underline]] = What filling materials A = Cotton flock also Wood flour, but cotton flock whiter. [[underline]] Question 7 [[/underline]] = What are its comparative flowing qualities of the molding powder? A = About 40% worse than phenol molding mixtures Phenol mm. - 250 kilos per sqr c.m Amino = 350 " " " this depends also on thickness and shape of objects Stands oil and alcohol 100%. He offered me [[strikethrough]] tables [[/strikethrough]] printed tables on all these and other data furnished by their physical testers Also allowed me to take any samples. - Tells me [[red underline]] Mr Carl Marks, [[/red underline]] editor of "Plastics" in New York is acquainted with whole patent situation and we [[strikethrough]] should [[/strikethrough]] ^[[may]] apply to him. He gave me full list of all his published patents and said that the patent agent best acquainted with any of the details of the situation is Dr. Alexander Wacker Gesellschaft fur Elektrochemische Industrie G.m.b.H. München Prinz regentstrasse - Fernruf: München [[strikethrough]] 20 - 621 [[/strikethrough]] 20 621 - 20 626 Was brought back at our office at about 11 AM. where Surcouf and Sachs awaited me. - I asked Surcouf how old he was. He admits he is 70. Papers all signed now and La Bakelite situation entirely settled. - What will come up next in France? - Had luncheon all together
