A core/base layer, an intermediate layer, a divider layer between the core and intermediate layers, and a water-resistant layer on the intermediate layer opposite the core layer. The core and intermediate layers are made of a cementitious material to provide structural-strength and fire-resistance properties, with the core layer including an aggregate material for added strength, the intermediate layer including an hydrophobic additive for water resistance, and the divider layer positioned between the core and intermediate layers to form a physical barrier that prevents cross-migration of the aggregate material and the hydrophobic additive between these layers. The water-resistant layer includes a fiber-based carrier layer with an outward-facing surface having a weather barrier layer secured to it and with an opposite uncoated inward-facing surface having loose fiber strands extending from it and embedded into the intermediate layer to secure the water-resistant layer to the intermediate layer.

Structural fire- and water-resistant panels, and manufacturing methods therefor

The present disclosure provides a PVC or CPVC solvent cement and a composition for forming a PVC or CPVC coating on an object. The solvent cement and the coating composition each include one or more caprolactam-derived solvents and a polymer selected from the group of polyvinyl chloride and chlorinated polyvinyl chloride. The one or more caprolactam-derived solvents include a linear alkyl group of 1, 2 or 4 unsubstituted carbons or an alkoxymethyl group of 2 or 3 unsubstituted carbons bonded to a nitrogen heteroatom.

Compositions including PVC or CPVC

Solvents that are suitable for use with polyurethane-polyurea based rheology modifying agents of the type which, in the past, have generally been formulated as solids or viscous liquids. The present solvents enable the rheology modifying agents to be prepared and formulated in a liquid or solution form more suited to prepare coating formulations that include polyurethane-polyurea based rheology modifying agents. The present solvents are N-alkyl substituted caprolactams, including N-methyl caprolactam, N-ethyl caprolactam, N-butyl caprolactam, and mixtures thereof, which are aprotic, non-toxic, have good solvency for polar groups such as those found in polyurethanes and polyureas, are thermally stable, and have high boiling points and low vapor pressure.
