Abstract
Resin compositions having a reduced solubility and methods for making and using same are provided. In at least one specific embodiment, the resin composition can include a phenolic resin, a latent acid, a catalyst, and a liquid medium. The catalyst can be a base compound and can be present in an amount of about 2 wt % to about 7 wt %, based on the combined weight of the phenolic resin, the latent acid, the catalyst, and the liquid medium.
Claims20
A resin composition comprising:
- a phenolic resin, a latent acid, a catalyst, and a liquid medium, wherein the catalyst comprises a base compound and is present in an amount of about 2 wt % to about 7 wt %, based on the combined weight of the phenolic resin, the latent acid, the catalyst, and the liquid medium.
A method for making a composite product, comprising:
- mixing a plurality of lignocellulose substrates and a resin composition to produce a resinated furnish, wherein the resin composition comprises a phenolic resin, a latent acid, a catalyst, and a liquid medium, and wherein the catalyst comprises a base compound and is present in an amount of about 2 wt % to about 7 wt %, based on the combined weight of the phenolic resin, the latent acid, the catalyst, and the liquid medium;
- and
- heating the resinated furnish to produce a composite product.
A composite product, comprising:
- an at least partially cured resinated furnish, wherein, prior to curing, the resinated furnish comprises a plurality of lignocellulose substrates and a resin composition, wherein the resin composition comprises a phenolic resin, a latent acid, a catalyst, and a liquid medium, and wherein the catalyst comprises a base compound and is present in an amount of about 2 wt % to about 7 wt %, based on the combined weight of the phenolic resin, the latent acid, the catalyst, and the liquid medium.
