[OOO] “OF [NPF] “Spectrum- varnish color” test center “varnish color”
RECORD SHEET OF THE TESTS of №152/06 dated October 26, 2006.
Designation of paints ([LKM]): - the weatherproof and chemically resistant enamel “Of [unipol]” of stamp V -[Se], green, p. 112, prepared 15.08.06[g].
Designation [ND] on [LKM] TU 2312-001-59846005-2003 “the enamel [SBE]-111 “Of [unipol]”.
Customer: Privately held company [NPO] “Of [korrzashchita]” (Russia, Moscow, ul old [Basmannaya], d. 36, p. 2) the purpose of the tests: To conduct the tests of coatings according to GOST 9.409-88 method A3. Date of idea [LKM] down testing of 03.09.06[g].
Periods of conducting tests (beginning- end): 11.09.06[g]. - 26.10.06[g].
Sampling and preparation at the point of the tests: Down the test center were transmitted 2 components of enamel V -[Se] - semifinished product and hardeners. The sampling of the components of the enamel V -[Se] of green was produced by customer. The packing of tests corresponded ALL-UNION STATE STAN. 9980.3-86 “materials varnish-and-paint. Packing”. Throughout the tests they thoroughly intermixed the semifinished product of enamel (green color), checked according to the presence of contamination and they filtered.
Conducting the tests
Before the application of coatings of the constituent of enamel (semifinished product and hardener) they mixed up before relationship 10: 1.
The stability of coatings to the action of petroleum products determined according to GOST 9.409-88 method A3, which provides for the alternating action of petroleum products and climatic factors of regions with the cold climate. As the petroleum products used a crude oil of Bobrovskiy layer g. Orenburg, diesel fuel- L -02-40 (ALL-UNION STATE STAN. 305) and gasoline of stamp A -76 (ALL-UNION STATE STAN. 2084).
Enamel V -[Se] was brought by paint sprayer beside two layers. Putting the second layer was conducted down the first, slightly gotten dry layer. Throughout the tests of coating they maintained during 12 days. The inspection of models was carried out through 1, 3, 5 and then through every 5 cycles. The physicomechanical indices were evaluated after the end of tests: adhesion and the strength of coating to the impact.
Results of the tests
The results of tests are given before Table 1.
Conclusion Are carried out the tests of coatings of priming enamel “[Unipol]” stamp V -[Se] (green, [p].112 from 15.08.06[g].) TU 2312-001-59846005-2003 “the enamel [SBE]-111 “Of [unipol]”. Technical specifications”.
Is determined the resistance of the coatings for the sake of the enamel V -[Se] of green to the alternating action of petroleum products (gasoline, to diesel fuel, oil) and climatic factors of region with the cold climate (method A3, ALL-UNION STATE STAN. 9.409-88). It is shown that after 20 cycles of the tests of coating satisfy the requirements ALL-UNION STATE STAN. 9.409-88 on the adhesion, elasticity, strengths of coatings with the impact and to the electrical properties (dielectric power factor). The two-layered coatings with the thickness of 120-140[mkm] maintain 20 cycles of tests with the indices, given before Table 5.
