A surface treatment agent and a surface treatment method capable of imparting excellent corrosion resistance while enhancing adhesion between a surface of a metal substrate and a resin-containing layer. The surface treatment agent for treating a surface of a metal substrate includes an acrylic resin having a carboxyl group and a hydroxyl group, an oxazoline group-containing compound and metal particles containing at least one of Nb, Ca and Nd. The metal may be in the form of a niobium oxide sol.

The present invention relates to a UV light reflective composition comprising a light transmissive matrix comprising a silicone resin, and UV light reflective particles comprising boron nitride, the particles being dispersed in the transmissive matrix. The light reflective particles of the UV light reflective composition has an average particle size within the range of from 0.2 to 0.7 m. An advantage of the present invention is that it provides a highly light reflective composition, especially in the UV range.

A method for manufacturing and applying a metal oxide coating for shielding an object from particle radiation includes heating a quantity of a resin of a polyurethane system and mixing a metal oxide with the quantity of the resin of the polyurethane system to form a mixture. The method further includes mixing a quantity of a hardener of the polyurethane system with the mixture to form a metal oxide infused conformal coating (MOICC). The method further includes applying the MOICC to an object to shield the object from particle radiation and curing the MOICC.
