Some embodiments of the present disclosure relate to a method comprising: obtaining a base formulation, obtaining an activator formulation, mixing the base formulation with the activator formulation, so as to result in a liquid applied roofing formulation, applying the liquid applied roofing formulation to at least one steep slope roof substrate, and solidifying the formulation, so as to form at least one coating layer on the at least one steep slope roof substrate. Some embodiments of the present disclosure relate to a liquid applied roofing formulation comprising a first part and a second part. In some embodiments, the first part comprises the base formulation and the second part comprises the activator formulation.

A reflective particulate composition includes a particulate substrate, and an inorganic binder, a pigment, and a hydrophobic coating on the particulate substrate. The composition may have a solar reflectance of 70% or greater. The pigment may include a clay, and the hydrophobic coating may include a (meth)acrylic polymer, a coupling agent, a wax and an antioxidant. A method of making the composition may include mixing the pigment, the inorganic binder, a dispersant and water to form a pigment mixture, adding the particulate substrate to the pigment mixture, heat treating the pigmented particulate, and mixing the pigmented particulate with a hydrophobic coating composition. Alternatively, the method may include first mixing the particulate substrate with one of the inorganic binder or the pigment, and then mixing the resulting composition with the other of the inorganic binder and the pigment, and heat treating the pigmented particulate.

The present invention describes a one-part moisture-curing liquid-applied waterproofing membrane having a polyurethane polymer, a long-chain aldimine and a hardener selected from an oxazolidine and another aldimine. The membrane has a low viscosity at low solvent content and a good shelf life stability and cures fast to form a solid elastic material. The membrane is particularly suitable for roofing applications, possessing high strength, high elongation and good durability under outdoor weathering conditions in a broad temperature range.
