IMPACT RESISTANT COATING COMPOSITIONS, MULTI-LAYER COATING SYSTEMS, AND SUBSTRATES AT LEAST PARTIALLY COATED WITH SUCH COMPOSITIONS
A curable coating composition includes: (a) a binder having a film-forming resin with at least two functional groups, and (ii) a curing agent reactive with the functional groups of the film-forming resin; and (b) solid vulcanized rubber particles that are unreactive with the binder. The curable coating composition is a solid particulate powder coating composition. Multi-layer coating systems, coated substrates, and methods of preparing the curable coating composition are also disclosed.
Coated spring
An electrically conductive component, which can be used in motor vehicles, may include a surface having a layered covering. The layered covering may be a melted and cured product of coating with a powder composition. Further, the layered covering may have a layer thickness of greater than 150 μm, and the layered covering may be a single-layer covering. The layered covering may also include a pore-like layer structure. The pore-like layer structure of the layered covering may be responsible for an at-least-15% reduction in density of the layered covering relative to a density of the layered covering without the pore-like layer structure.
COMPOSITIONS FOR INHIBITING CORROSION
The present disclosure relates to agents, compositions, and methods for inhibiting corrosion in various substrates, for example in metal substrates. The present disclosure also relates to compositions for inhibiting corrosion comprising at least one organic heterocyclic compound and at least one metal salt or mixed metal salt selected from rare earth, alkali earth and transition metals.
Multi-purpose flexibility additive for chemical coating compositions
A multi-functional flexibility additive that reduces surface imperfections such as orange peel, facilitates lower viscosity during endothermic reactions, provides high flexibility to the final, cured coating, and possesses chemical resistance is contemplated. The additive is formed as a binder system adhered to a resinous flow aid carrier at a preferred weight ratio of 40:60 (binder:carrier).
Multi-functional flow modifier for chemical coating compositions
A multi-functional flow modifier that also serves as a wetting agent, gloss control additive, and rheology modifier is contemplated. The flow modifier itself is a mixture of polyurethane masterbatch and hydroxyl acrylic resin (free from any styrene components/resins), curatives, anti-corrosion pigments, degassers, and anti-oxidants. The flow modifier may be introduced to finished coating compositions by way of a silica carrier.

Powder coating compositions capable of having a substantially non-zinc containing primer
Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, can be formed from a coating composition comprising a primer having an epoxy resin with the proviso that the epoxy resin does not have an EEW of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a HEW of about 200 to about 500, and a platy filler. The primer contains less than 20 wt % zinc. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 450 to about 1400, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a foaming agent and a reinforcing fiber.
