CONTENT:
Adhesive KT-30 (Industrial standard 6-02-760-78) is a solution of polyorganosilazane resin in toluene. The adhesive is one-component and cures at the room temperature for 48 hours. The adhesive joint is corrosion-, fungus-, water- and weather proof, works in the temperature range from -60 to 300оС. When cured the adhesive doesn’t emit volatile substances, retains its properties unchanged under the influence of ozone, coronary discharge, sunlight and radiation.
APPLICATION:
It is used for bonding to vulcanized rubbers based on silicon rubbers and for attaching them to the metals, as adhesive sublayers for adhesives and enamel surfaces, metals with metals, ceramic products, silicate and organic glass, wood, leather and etc.
