Resin compositions for powdery coatings which contain the components (A), (B) and (C) as specified below: (A) a carboxyl-containing resin having a number-average molecular weight of 1,000 to 20,000, an acid value of 5 to 200 and a glass transition temperature of 30 to 120 °C; (B) a poly-β-methylglycidyl compound carrying at least two structures represented by formula (1) per molecule; and (C) a steric-hindered amine as a heat yellowing inhibitor.
摘要:
A matte powder coating composition including a first carboxyl- functional polyester resin, a second carboxyl-functional polyester resin, and an epoxide-functional crosslinking agent, where the difference in acid values between the first and second carboxyl-functional polyester resins is from about 200 to about 350 mg KOH/g.
摘要:
A coating composition includes a base coating resin; and an overlay coating resin; where the base coating resin includes micro-impressions and planar areas, where the following expression is satisfied for the coating composition: P*TB >A*TO, where A is the area of the micro-impressions, P is the area of the planar areas, TB is the tensile strength of the base coating resin, and TO is the tensile strength of the overlay coating resin. In some cases, TB, is greater than TO. A process for preparing the coating compositions includes applying a base coating resin to a substrate, micro-impressioning a top surface of the base coating resin to provide a micro-impressioned top surface of the base coating including micro-impressions and non-impressioned planar areas, and applying an overlay coating resin to the micro-impressioned top surface of the base coating.
