Hetrick - Hampton Works We hare completed the basic engineering this C.O.D. request. This projeot was initiated In an effop&i^ Hicarta product that had fire-resistant properties, corr^ai&^resl , and an acceptable surface appearance. In previous applieat ested that our Aluminum Bonded Hicarta be used la such ever, we were Informed that . this would not be acceptable a because of the corrosion of the Aluminum by salt spray, develop a new product that would be suitable for this app! ' several laboratory samples. I will outline each of these pr observations. . The first saaple a decorative surface directly to a Johns-Manvilie M rinite & laoe most any product that we develop will be glued to installation, it was felt we could offer some advantagu^by .ding surface directly to the Marlnite. In a patent disclosure we disclosed that it was possible to mold a sur face , Flexboard, and Transite if an epoxy binder sheet was us Moratory samples were molded using this Information, It eptable surface could be obtained. It Is felt that to mold some 50 x 100 site sheets to state definitely can be made on shop equipment. We might encounter rupture Core on large sise sheets. One sheet was molded In the Small The cure on this board was not adequate and sticking was - tend series of boards was made using l/8 Flexboard as a core. Here . an epooqr hinder was used. These samples were made after the Sales Departpresented a saaple of Johns-Mamville Deluxe Flexboard which bed been red for this job. This aaiple was a Flexboard produet with a D.A.P. sur face. We ware able to sold two boards of the melamine surfaoed Flexboard on the `mail Baldwin without difficulty. Upon investigating Jobns*Jfanville litera ture, 1 believe the Deluxe Flexboard was nolded on one of their asbestos pro ducts known as Asbestoeite Type "B". This Is a leas dense product than commercial Flexboard. We ran comparative testa betwqa-the Hicarta and the Deluxe Flex board and the Mlcerta baa certain advantagea. (Sea attachment) 00000019 Hr. 0. E. Baldwin >2' January 31, 1956 The third series of boards consisted of a board molded using one of our inc el-treated asbestos materials as a core. Several boards were molded with construction - 1 sheet 5H2U overlay, 1 sheet surface, 7sheets 5Ul. 5Ul .010 asbestos paper treated vith a phenolic resin. These face appearances. We -encountered no difficulty in molding caution, the asbestos paper used on Ski will occasionally "hard-spots*. These spots are high density areas. I the surface appearance and might possibly damage our pres could manufacture this product vith care and inspecticn->oX^the If this product should be approved, ve can possibly get's* betpaper but this would greatly increase the cost* The fourth series of boards was molded using es tq as a core material. Using the information acquired on the Air demy jd , ve were quite success ful in bonding a melamine surface to the ie bnss the sand blasting machine in "A" Buildins boardd'vere molded with the following constructions - 1 sheet 5&lli\V*he< face, 1 sheet 5EL9> 1 sheet .032 Brass (sand blasted), 1 sheet 2^sh 299. The bond on these samples was good. The fifth series of boards was a core material. We found the equipment available construction - 1 sheet ove^lj^, 1 glass mat. The resin on the^gli The surface appearaac^of the practical and non ' ~/ lenolic-treated glass mat as -. .. impossible' to treat the mat with ' ^ TWo boards were molded vith this surface, 1 sheet 5B3&3* and 1 sheet thru to the decorative surface, i was poor. In my opinion, it is both in to aaanfacture this product on shop equipment. An approximate cm as made oh each of the above products. (See attachment) Since ve these si tbs fori' certain as to the product that will be used as bulkheads on --;eat that all these saaples be presented to the customer in It appears from our results that the melamine faced >le made vith the asbestos paper core hare the best possithe requirements for this installation on quality and price. the sables mentioned above, ve have saaples of .025 aluminum, traction and .035 steel, balanced construction.
