摘要:
A catalytic converter holding mat that is inexpensive, and exhibits an excellent heat insulation capability is provided by utilizing an inexpensive heat insulating material that exhibits an excellent heat insulation capability. The catalytic converter holding mat is provided in a gap between a tubular catalyst carrier and a casing that houses the catalyst carrier, and includes a retaining section that is formed of first inorganic fibers having a thermal shrinkage ratio at 1000° C. of 1% or less, and an insulation section that is disposed adjacent to the retaining section, and formed of second inorganic fibers having a thermal shrinkage ratio at 1000° C. of more than 1%.

A coating composition comprising 38%-66% of a binder resin (including a curing agent), 0.2%-6% of an organic lubricant, 20%-50% of an iron phosphide-based electrically conductive pigment, and 3%-25% of one or more other inorganic pigments including anticorrosive pigments (the total content of these pigments being between 31% and 56%), wherein the content of the binder resin (including a curing agent) (R) and that of the organic lubricant (W) satisfy the following inequality:-0.4R+16.2.ltoreq.W.ltoreq.-0.4R+30.4, andwherein the coating composition further comprises a curing catalyst in an amount of from 0.7% to 10% based on the solids of the binder resin (including a curing agent). The coating composition can be applied to a plated metal sheet having a zinc- or aluminum-based plated coating after the plated metal sheet has been subjected to chemical conversion treatment such as chromating treatment, to form a resinous coating thereon having a thickness of 2-9 .mu.m, thereby resulting in the production of a resin-coated metal sheet having improved overcoat adhesion, weldability, edge face corrosion resistance, and formability, which is suitable for use as a material for automotive repair parts.
摘要:
An organic lubricating coating composition for use in plastic deformation of a metal sheet comprises a maleic anhydride/styrene copolymer which has been at least partially esterified with one or more organic hydroxy compounds, or a salt of the esterified copolymer. The molar ratio of the maleic anhydride component to the styrene component in the copolymer is in the range of from 1:99 to 75:25. At least 10% by weight of the organic hydroxy compounds is comprised of a long-chain hydroxy compound containing from 10 to 30 carbon atoms.
