A silicate-modified polymer grouting material for leakage plugging is provided, which belongs to the technical field of silicate modification, includes 60% by weight of silicate-modified aqueous solution component, and about 40% of structural flame-retardant isocyanate. According to the proportion of the main total amount, the main components are classified into inorganic components, so the silicate-modified polymer grouting material for leakage plugging has excellent flame retardant performance, oxygen index 35%, adhesion 1.5 mPa, maximum reaction temperature 95 C., odor level (80 C.) 3.5, fog test 5 mg (without physical additive flame retardants diffusion to the environment). In particular, a main component of the silicate-modified aqueous solution, endows it with good surface resistance.

A vacuum insulating panel includes may include: a first glass substrate; a second glass substrate; a plurality of spacers provided in a gap between at least the first and second substrates, wherein the gap is at a pressure less than atmospheric pressure; a seal provided between at least the first and second substrates, the seal including multiple layers. Edge stress in at least one of the glass substrates may be reduced by providing an edge(s) of at least one of the glass substrates with reduced surface roughness and/or by tempering the glass substrate(s) with at least one seal layer, such as a primer layer, thereon.
