PURPOSE: A silicon-containing composition is provided to be used as foaming agent or a deaerator for an airless spray composition by including a polyether-modified silicon in a coating composition. CONSTITUTION: A composition comprises a linear polyether-modified silicone and a copolymer has a chemical formula: M'DmM'. In the chemical formula, M' is (CH3)2(G)SiO-, D is -(CH3)2SiO-, G is -(CH2)n-O-(CH2-CH2-O)X-(CH2-CH(CH3)-O)YZ, m is 3-50, n is 1-6, X is 0-20, Y is 2-50, Z is hydrogen, methyl, butyl, or acetyl group. A manufacturing method of a polyether silicon comprises a step of contacting one or more silicon structure capped with polyether in a hydrosilylation condition under the presence of one or more solvents and one or more catalysts. |
