The present invention relates to resin coated silica which is obtained by coating silica that has a nitrogen adsorption specific surface area as determined by a BET method of 50-300 m2/g sequentially with a first coating material and a second coating material. The resin coated silica is characterized in that the first coating material contains a phenol, and the second coating material contains (A) a novolac type phenolic resin and a curing agent and/or (B) a resol type phenolic resin. The present invention is capable of providing: resin coated silica which has good kneadability with a rubber and excellent hardness imparting effect; and a rubber composition and a tire, each of which enables a good balance between steering stability and improvement in the fuel efficiency of a vehicle due to decrease in the rolling resistance of tires.
The present invention relates to: a binder for use in the production of an inorganic fiber product, which comprises a phenolic resin and a sugar; a binder for use in the production of an inorganic fiber product, which comprises a first preparation comprising a phenolic resin and a second preparation comprising a sugar; and a process for producing an inorganic fiber product, which comprises adhering the binder for use in the production of an inorganic fiber product onto inorganic fibers and molding the inorganic fibers to produce the inorganic fiber product. The present invention can provide a binder from which formaldehyde is diffused in a reduced amount and which enables the production of an inorganic fiber product having good properties at low cost and a process for producing an inorganic fiber product.
Disclosed is a production method for a biomass phenol resin that includes reacting a phenol containing an unsaturated alkyl phenol derived from a plant material and a sugar containing a fructose source of more than 50% by mass, in the presence of an acidic catalyst. Also disclosed is a thermosetting material which contains the biomass phenol resin and a curing agent. The biomass phenol resin production method can produce a biomass phenol resin that can obtain a cured body of high strength and a low Young's modulus in addition to excellent moldability and a high plant-derivation ratio. The thermosetting material can produce a cured body of high strength with a low Young's modulus, excellent moldability and a high plant-derivation ratio.

WATER TREATMENT METHOD AND WATER TREATMENT FLOCCULANT
Provided is a water treatment method which uses a water treatment flocculant comprising a phenol resin-based alkali solution, and with which there is very little secondary pollution due to flocculation residue. The water treatment method involves adding the flocculant to the water to be treated and subjecting the product to membrane separation. The flocculant is formed from an alkali solution of a phenol resin having a melting point between 130ºC and 220ºC. The water treatment flocculant is obtained by adding an aldehyde to an alkali solution of a novolak phenol resin obtained by reacting a phenol and an aldehyde in the presence of an acid catalyst, and then performing a resol-type secondary reaction in the presence of an alkali catalyst.

BINDER COMPOSITION FOR CASTING MOLD FORMATION AND PROCESS FOR PRODUCING CASTING MOLD USING THE BINDER COMPOSITION FOR CASTING MOLD FORMATION
A binder composition for casting mold formation which can give a casting mold having sufficient strength without complicating the production step; and a process for producing a casting mold using the binder composition for casting mold formation. The binder composition for casting mold formation is characterized by comprising an acid-curable resin, water, and the chloride of a metal. The composition is further characterized in that the acid-curable resin comprises furfuryl alcohol and one or more products of the condensation or co-condensation of one or more members selected from a group consisting of furfuryl alcohol, phenols, and urea with an aldehyde, and that the metal is an alkaline earth metal and/or a zinc-family element.
