The present invention relates to a form coating agent, which has an adjusted acid value and a function of releasing forms from concrete. The present invention uses a copolymer containing: A) melamine polymer resin; B) polystyrene resin; C) phenol-formalin resin; D) polymethylmethacrylate; E) polyacrylate-based resin; and F) polyvinyl chloride.

The present invention provides an aqueous coating composition which is capable of forming a coating film that has excellent cissing resistance and water resistance. An aqueous coating composition which contains (A) at least one hydroxyl group-containing resin that is selected from among (A1) hydroxyl group-containing acrylic resins and (A2) hydroxyl group-containing polyester resins, (B) an oligomer and (C) an alkyl etherified melamine resin, wherein: the oligomer (B) has a number average molecular weight within the range of from 200 to 800 and a solubility parameter within the range of from 10.0 to 13.5; and the molar ratio of methyl groups to butyl groups in the alkyl etherified melamine resin (C), namely (methyl group)/(butyl group) molar ratio is from 50/50 to 0/100.

An impregnate with antistatic properties for use in laminates or for coating wood-based panels is disclosed. A resin used for impregnating and/or coating paper may include carbon-based particles, at least one compound of the general formula (Ia) R.sup.1.sub.aSiX.sub.(4-a), R.sup.3.sub.cSiX.sub.(4-c)(II), and inorganic particles. X is methoxy, ethoxy, n-propoxy or i-propoxy. R.sup.1 is an organic radical selected from the group including methyl, ethyl, propyl, or vinyl, and has at least one functional group Q.sub.1, selected from the group including acrylic, acryloxy, methacrylic, methacyloxy, or epoxy. R.sup.3 is a non-hydrolyzable organic radical selected from the group including C1-C10 alky, C6-10 aryl, wherein C is 1, 2, or 3, and the inorganic particles have a size between 2 nm and 400 nm.

Disclosed are particles that have an exterior surface coated with a thin polymeric coating, such as a coating that includes a sulfur-containing polymer. Also disclosed are compositions, such as fuel-resistant sealant and coating compositions, which include such particles. Aerospace vehicles having an aperture at least partially sealed with a sealant deposited from such a sealant composition are also disclosed.
