A nail sticker, a composition for the nail sticker and a method for preparing the composition are disclosed. Raw materials of the composition include a sizing material, which is made of the following raw materials in parts by weight: 45-85 parts of a UV thermosetting resin, 2-9 parts of a photoinitiator, 1.5-2 parts of a curing agent, 0.1-1 part of a thermal promoter, and 0.1-1 part of a leveling agent. The synchronization of the release of essential oil molecules with light/thermal curing promotes the essential oil molecules to be diffused to the interior of the sizing material more uniformly in a wider range, and during the curing and film forming of the nail sticker, an aroma spreads as tantalizing as that of baked food.

An electrocoat system for electrodeposition is described. The system includes an inorganic bismuth-containing compound or a mixture of inorganic and organic bismuth-containing compounds. The system demonstrates a high degree of crosslinking and produces a cured coating with optimal crosslinking and corrosion resistance.

Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including the reaction products of: (i) an organofunctional silane; (ii) an epoxy; (iii) an amine; (iv) an isocyanate; (v) an epoxide curing agent; wherein the controlled release particles are effective to retain the at least one hydrophobic active ingredient upon exposure to water and effective to release the at least one hydrophobic active ingredient in response to friction. A method for preparing the composition is also disclosed.

In developing epoxy resin compositions used as an adhesive for structure (structural adhesive) required to have adhesive properties, if each component is increased to further enhance the adhesive properties such as shear bond strength and peel strength, this causes problems, for example, as follows. The viscosity becomes so high that the workability deteriorates. Hence, the added amount has to be limited. Moreover, the cured product becomes excessively flexible, so that the shear bond strength deteriorates. An epoxy resin composition contains the following components (A) to (E), where the component (A) does not include the component (C): the component (A): an epoxy resin; the component (B): a blocked urethane resin; the component (C): a rubber-modified epoxy resin; the component (D): rubber particles; and the component (E): a latent curing agent.

Provided is method of making a three-dimensional object comprising polyurea, which may include: (a) dispensing a one part (1K) dual cure resin into a stereolithography apparatus, the resin comprising or consisting essentially of a photoinitiator, a reactive blocked polyisocyanate, optionally a catalyst such as a polyurethane blowing catalyst, and optionally a polyepoxide; (b) additively manufacturing from said resin an intermediate object comprising the light polymerization product of said reactive blocked polyisocyanate; (c) optionally cleaning said intermediate object; and (d) reacting said polymerization product in said intermediate with water in the presence of a catalyst such as a polyurethane blowing catalyst (which may be included in the resin, the water, or both) to generate polyamine in situ that sequentially reacts with the remainder of the polymerization product to form urea linkages and thereby produce a three-dimensional object comprising polyurea. Dual cure resins useful for the method are also provided.

There are provided a silyl-terminated resin composition and a method for producing the same, the silyl-terminated resin composition being superior in storage stability before curing and providing a cured product which has a low initial modulus and can maintain the low modulus even after a heat-accelerated test.
