OHIO SEALANTS INC #1131897
OSI HM-270 is a high modulus, one-part RTV silicone sealant designed for glazing and sealing. It cures at room temperature upon exposure to moisture in the air providing good tensile strength and excellent adhesion, usually without the use of a primer, to most non-porous building materials. HM-270 easily withstands temperature extremes from -60 deg F to 400 deg F without adverse effects. It is highly resistant to ultraviolet light and is virtually unaffected by other harsh environmental elements. HM- 270 offers superior elasticity and long-life reliability. It forms a permanent watertight and weatherproof bond to materials like glass, ceramics, aluminum, primed steel and some plastics.
