Title:
SEALING MATERIAL COMPOSITION HAVING APPEARANCE OF ROUGHNESS
Document Type and Number:
Japanese Patent JP3504457
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a sealing composition which can give a joint having the appearance of a quality product and having quality well matched with an external wall to the external wall material to which a sand scattering coating or a sandstone-like coating is applied and to which the appearance of roughness is imparted without detriment to the inherent performances by adding a specified amount of balloons having a specified or larger particle diameter to a sealing material composition.
SOLUTION: The balloons mean a hollow spherical filler. They are made of e.g. an inorganic material such as glass or 'Shirasu', a kind of pumiceous stone, or an organic material such as aphenolic resin or a urea resin. They should have a means particle diameter of 100μm or above and are added to make 5-25vol.% of the formulation ratio. The sealing composition is formulated with a polymer (e.g. modified silicone) as a base with a filler (e.g. calcium carbonate), a plasticizer (e.g. dibutyl phthalate), a solvent (e.g. toluene), additives (e.g. curing catalyst, antioxidant, ultraviolet absorber and silane coupling agent), etc.
