] / FQSEGO, S!\3C INTER-COMPANY AND INTER-DEPARTMENTAL CORRESPONDENCE to: J. E. Williams F. I. L. from: D* J. Anderson date: February 6, 1974 SUBJECT: Dear John, We commenced full blow development work of the Seal-On Gasket system yesterday. After obtaining the Hobart and press tool on Friday, we were able to complete some evaluation work last week. I have forwarded a copy of the proposed development program and must mention that our initial work is showing sore promise. I should be in a better position to discuss the progress during our Friday telephone conversation. I've written to Geoff Swinnerton re patents and would be obliged if you could chase him up on the subject, as I feel this area is very important; so important that I would be obliged if you would ask Geoff to discuss it with Richard Gallafent. I sat in on a technical/production meeting on Monday and the following may be of interest. OVZi; CAPACITY This has previously been cited as the limiting factor to increased production. However, R & D's new recipe, EP-5465, has enabled oven throughput times to be drastically reduced, by up to. 25%. A further analysis of the system now reveals that pulping capacity is the limiting factor. Machine capacity is far less of a problem. ASBESTOS REPLACEMENT The limit time for complete elimination of asbestos is now April 1st. Foseco,.Inc, has suitable Proflex and Profox 31 recipes but to date their slurry Seal-On recipes do not Include an asbestos-free type. The only problem is that all Foseco, Inc.'s asbestos-free recipes require Wollastonite, and the story behind this is as follows: the limiting factor to complete availability of this material is the mine's crushing'capacity. They planned to install new machinery last November to satisfy demand but now they do not see this equipment being installed until April. Problems: if the health authority pushes. 2791 J. . Villiaras \ 2 February 6, 1974 Back co ocher copies: ALTTRM.MIVS BTOPERS I enclose a copy of Don Bucler's work in chis direccion and would draw your accention co recipes U and V which are P.V.A. Poly Vinyl aceCate Cypes. Recipe which has a low cransverse strength, was bound with a liquid resin derived from eicher coal or petroleum discillace residue-.' The system is a two pack and I suspect chat one concains phenol (from its smell), and che ocher UF or formaldehyde. Uork with animal glues in conjunction with starch recipes, LMS 0, gave inadequate transverse strength. FE53UXES Bob Reardon, (Foseco, Inc.'s Ferr\ut expert) maintains that he has a number of interesting recipes which he has agreed to map out as comparisons against the samples you are forwarding. He and I intend to get together and formulate a comparison sheet, price and performance wise, which may enable us to suggest suitable modification. Bob also has a couple of very lot-? fume, non-P!i53l containing recipes, together wich a completely fumeless 531 type. * Ferrux granulation has been briefly viewed and Kerosine incorporated at 1&, this seems to give an improved product. The only problem could be that che competition would recognize the smell, perhaps other odorless petrochemicals could be used? . HOT BOX I've written to Phil outlining my thoughts on the development work with suggestions for future actions. LOV ENERGY CURB My letter to havid briefly explained that 1 have beer, unable to obtain ary '*seful. infor:.:aton on the free flowing particulate (cold cure) work allegedly conducted at Foscco, Inc. I hope to get some useful information on cold cure resin systems from U.S. Reps* All the best* DJA/cel 2792
