Introduction to two-component polysulfide elastic sealant:< br/> Two-component polysulfide elastic sealant is formulated with liquid polysulfide rubber as the base material. It is a polysulfide sealing paste that can self-vulcanize and cross-link at room temperature. It has good adhesion to metals, concrete and other materials and continues to stretch. It maintains good air tightness and waterproofness under vibration and temperature changes, and is oil and solvent resistant and has excellent durability.
Features of two-component polysulfide elastic sealant:
Adhesion: Polysulfide sealant has good adhesion to cement, steel, glass, wood, natural stone, etc. In general construction and water conservancy projects, polysulfide sealants with low modulus and high elongation should be used for their bonding strength. Elongation%.
Water resistance: The effect of polysulfide sealing paste on seawater, tap water and distilled water is stable, while the weight change on seawater is minimal.
Acid and alkali resistance: Polysulfide sealing paste is not resistant to concentrated acid and alkali. But it is stable to dilute inorganic acids, bases and various salts.
. Heat aging resistance: Polysulfide sealing paste has very good heat aging properties and can work under the conditions of 1℃~℃ for a long time.
Good radiation resistance: Polysulfide sealing paste has very good resistance to r_rays.
Non-toxic: Although the liquid polysulfide sealing paste has a bit of sulfur smell, it is gradually absorbed by the filler after solidification. The polysulfide sealing paste produced by our company has been tested by the Institute of Environmental and Hygiene Engineering, Chinese Academy of Preventive Medicine Sciences. It is classified as non-toxic according to the national toxicity classification standards.
Good air tightness: Polysulfide sealing paste not only has good elasticity, but its air tightness is also the best among elastic sealants.
How to use two-component polysulfide elastic sealant:
Treatment of the sealed surface Before using Lutong polysulfide sealant (glue), remove the oil, attachments and dust on the adhered surface. and other debris to ensure that the bonded surface is dry and flat to prevent poor bonding.
Fill the backing material into the seams according to the design requirements.
, Applying the primer liquid Design projects that require the use of primer liquid or the sealing of long-term water-immersed parts require the primer liquid to be applied on the adhered surface and dry to form a film.
Preparation of sealant When using polysulfide sealant, please mix the two components evenly according to the mixing ratio given in the instruction manual before use. Whether machine mixing or manual mixing, the color should be uniform without color difference. When mixing, air bubbles should be prevented from being mixed into the glue. When applying glue, air bubbles should be prevented from being mixed into the sealing area.
