Abstract
Изобретение относитс к получению гуммировочных и герметизирующих покрытий на поверхности стали, дерева и др. Изобретение позвол ет повысить адгезию к нержавой и ржавой металлическим поверхност м и стойкость к воде за счет использовани в качестве отвердител триэтаноламина (2 - 3 мас.ч.) и дополнительно насыщенного раствора хлорида железа (III) в воде или ацетоне (2 - 3 мас.ч.) в сочетании с форполимером на основе олигобутадиендиола и толуилендиизоцианата с массовой долей изоцианатных групп 2,8 - 4,3 % (95 - 105 мас.ч.) 2 табл.The invention relates to the preparation of gumming and sealing coatings on the surface of steel, wood, etc. The invention improves adhesion to stainless and rusty metal surfaces and water resistance by using triethanolamine (2 to 3 parts by weight) as a hardener and additionally saturated solution of iron (III) chloride in water or acetone (2 to 3 parts by weight) in combination with a prepolymer based on oligobutadiene diol and toluene diisocyanate with a mass fraction of isocyanate groups of 2.8 to 4.3% (95 - 105 parts by weight ) 2 tab.
