WesBond

What WesBond does

WesBond Corporation is a privately held specialty chemicals manufacturer founded in 1976 in Wilmington, Delaware, by Wes Jones and Wes Weidman, both formerly of DuPont. The company develops and produces colloidal silica, colloidal alumina, cationic starches, refractory coatings, and proprietary complete binder systems used to bond refractory ceramic fibers, mineral wool, and soluble fibers into insulating boards and shapes designed for direct exposure to flames or molten metals. Its portfolio of more than 20 products is organized into six categories: complete fiber-bonding systems (Wesil CS, HT, NS, PRX, RP), colloidal silicas (Levasil, Megasol, Wesol P), colloidal aluminas (Wesol A, Bluonic A, Wesol D30, Wesolok line), cationic starches (Westar+ and Westar+3), refractory coatings (Wesrock RFC #17), and processing additives (PSA, PS9400W, QDA, AF2024).

The company serves manufacturers in the vacuum-forming, foundry and smelting, investment casting, and artificial fireplace log industries. Two US patents (5,945,049 and 6,214,102) protect its use of high-concentration wide-particle-size colloidal silica to produce stronger vacuum-formed shapes with improved high-temperature properties. Its Wesil systems combine proprietary aluminosilicate binders with cationic cold-water swelling corn starch in master-batch form, reportedly reducing customer formula costs 30–40% versus conventional silica/starch systems and serving as drop-in replacements for phenolic resins in foundry riser sleeve applications. The Wesil HT system targets repeated molten steel contact at 2700°F.

WesBond operates a B2B direct sales model with quote-based pricing, multiple ordering channels (phone, email, fax, US mail), and personalized technical support managed by Technical Manager Wes M Jones. The company ships domestically via UPS, FedEx, and freight carriers and internationally using UPS, FedEx, and Schenker with ISPM-compliant packaging. Standard credit terms are net 30 days, with finance charges on overdue balances and a 20% restocking fee on returned standard items. The firm reports 1–10 employees, has no external funding, no parent company, and remains under founder/president Wes Jones's ownership and operational control.

Products and services

• Wesil CS A complete refractory fiber floccing and bonding system that replaces both colloidal silica and starch, containing cationic cold-water swelling corn starch blended with proprietary aluminosilicate binder. Typically reduces formula costs 30-40% below traditional colloidal silica/starch systems.
• Wesil HT High temperature system designed for repeated contact with molten metal, containing heat-setting proprietary binder for green hardness and refractory additives allowing conventional ceramic fibers to withstand molten steel contact at 2700°F. Used for thermocouple shields and molten metal contact applications.
