The inventive method for forming a cured film on a substrate surface comprises coating the surface with a room temperature curable organosiloxazane polymer comprising, in a molecule, (a) at least one organosiloxane unit represented by the unit formula (a) at least one organosiloxane unit represented by the unit formulaR.sup.1.sub.a SiO.sub.(4-a)/2,and (b) at least one organosilazane unit represented by the unit formulaR.sup.2.sub.b Si(NR.sup.3).sub.(4-b)/2,in which R.sup.1, R.sup.2 and R.sup.3 are each a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, not all of them being simultaneously hydrogen atoms, and the subscripts a and b are each a positive integer of 1, 2 or 3 with the proviso that a and b cannot be simultaneously equal to 3, in a molecule and subjecting the coating film to exposure to a moisture-containing atmosphere. The method is useful for forming a surface-protecting film or for imparting surface releasability.

Improved magnetic media comprising a non-magnetic substrate and a magnetic layer formed on at least one side of the substrate. The magnetic recording media are provided in a variety of ways with a specific type of organosilane compound serving as a lubricant and represented by the following general formula: ##STR1## where R is a saturated or unsaturated monovalent hydrocarbon residue having from 7 to 21 carbon atoms, n is 0, 1 or 2, and p is an integer from 1 to 12. The organosilane lubricant compound may be incorporated in the magnetic layer itself, in a back coating layer, or it may constitute a layer on the magnetic layer or on the back coating layer.

The rubber composition is formulated with (A) a combination of an ethylene-propylene copolymeric rubber and an organopolysiloxane having at least two alkenyl groups per molecule as the polymeric base, (B) a reinforcing silica filler, (C) an alkoxysilane compound and (D) a thiocarbamyl-containing organosilane compound. The rubber composition can be vulcanized with an organic sulfur compound or organic peroxide as the vulcanizing agent to give a vulcanizate having quite satisfactory mechanical properties including, in particular, greatly improved heat resistance and greatly decreased permanent compression set even without using carbon black as the reinforcing filler. The omission of carbon black in the formulation gives an advantage that the rubber may be colored in any light color.

An electronic component package has a first sealing member main surface with mounted electronic element, and a second sealing member. An outer circumference portion of a second sealing member is molded into a tapered shape, providing a tapered area in at least part of the outer circumference. A flat area adjacent to the tapered area is provided in at least part of a flat portion inward of the outer circumference portion of the surface of the second sealing member. A first area corresponding to the tapered area and a second area corresponding to the flat area are provided adjacent to each other on a first main surface of the first sealing member with mounted electronic component element. A width W2 of the second area is 0.66 to 1.2 times a width W4 of the flat area. First and second bonding layers are formed and bonded with each other by heating.
