Resin systems and methods for making and using same are provided. The resin system can include a first aqueous resin comprising at least two polymerized monomers and a second aqueous resin comprising at least two polymerized monomers. The first aqueous resin can be present in an amount of about 5 wt % to about 95 wt %, based on the total weight the resin system. The second aqueous resin can be present in an amount of about 5 wt % to about 95 wt %, based on the total weight the resin system. The at least two polymerized monomers of the first and second aqueous resins can be the same monomers.

Resin systems for making composite products

The present invention relates to an aqueous phenol-formaldehyde resole resin prepared by reacting phenol and formaldehyde in the presence of a source of calcium ions, to a curable powdered (particulate) resole resin made by spray drying the aqueous phenol-formaldehyde resole resin, to a method of preparing a wood composite using the curable, powdered resin, and the related wood composite bonded with the curable, powdered resin.

Bonding wood composites with a calcium-modified phenol-formaldehyde resin

Methods for producing spray-dried phenol-formaldehyde resole resins and products made therefrom. The method can include spray-drying an aerated liquid phenol-formaldehyde resole resin containing about 0.02 wt % or more of a surfactant, based on a combined weight of the liquid phenol-formaldehyde resole resin and the surfactant, to produce a spray-dried phenol-formaldehyde resole resin powder.

Method of spray drying phenol-formaldehyde resin

The invention comprises an aqueous phenol-formaldehyde resole resin liquid fortified with powdered (e.g., spray dried) phenol-formaldehyde resole resin, preparing wood composites, particularly oriented strand board (OSB), waferboard, particleboard, medium density fiber board, and hardboard, using the solids-fortified liquid resin, and related wood composites bonded with the solids-fortified resin.

Bonding wood composites with resin solids-fortified phenol-formaldehyde resin

The present invention relates to a method for preparing a wood composite, and the related wood composite itself formed by steam injection pressing using a phenol-formaldehyde resin binder composition capable of rapidly curing in a saturated or superheated steam atmosphere.

Wood composites bonded with phenol-formaldehyde by steam injection pressing

A phenol-formaldehyde resin, having a low concentration of tetradimer, making the resin suitable for preparing a binder composition for making non-woven fiber products, such as fiberglass insulation, prepared by reacting phenol and formaldehyde in the presence of a sulfite source.

Phenol-formaldehyde resin having low concentration of tetradimer

A seed for enhancing the extended delivery of nitrogen needed for plant development and growth, the seed having a slow release nitrogen coating of a particulate UF polymer adhered to the seed with an adhesive binder.

Slow release nitrogen seed coat

A slow release, particulate urea-formaldehyde polymer useful as a fertilizer for enhancing the extended delivery of nitrogen needed for plant development and growth and a granular fertilizer made with the particulate urea-formaldehyde polymer.

Slow release nitrogen fertilizer

A method for treating a seedling by dipping the roots of the seedling into a composition containing a slow release, particulate urea-formaldehyde polymer, which is useful as a fertilizer for enhancing the extended delivery of nitrogen needed for plant development and growth and to the composition useful as the root dip, or as a soil drench.

Slow release nitrogen root treatment

A coated aggregate material for enhancing the extended delivery of nitrogen needed for plant development and growth, the coated aggregate material having a slow release (extended-release) nitrogen coating of a particulate UF polymer adhered to the aggregate material with an adhesive binder.
