Release Agents
Our Nix Stix family of releases agents are designed specifically to complement our Resin product offerings.
Formulas specifically designed for Cold Box, No-Bake, and Heat Cured processes include solvent based and Low Volatile Organic Compound (LVOC) formulas to meet your environmental needs.
Key advantages of this product line are the reduction in build-up on tooling, rapid drying, better core definition, and easier stripping of cores.


Shell Hesive
Our ShellWeld product line offers both ready to use and high viscosity hot shell core and mold pastes that can be applied directly to hot shell cores and molds.
When applied to a hot shell core or mold, ShellWeld does not boil or dry out rapidly, thus allowing machine operators sufficient time to position cores and mold halves.
Our ShellWeld products also utilize a renewable resource (vegetable oil) as the liquid carrier and is a perfect companion to our Resin Coated Sand products for the Shell process.


Core Pastes
Our core paste adhesive line, CoreWeld, comes in two forms, standard and thick, to offer the most variability in set up time.
Our water based formula is a ready to use air dry pink paste that is silica free. It is ideal for automatic dispensing systems because it does not contain material that will abrade or wear out equipment.
Our acetone based formula utilizes a fast drying organic solvent that is not classified as a VOC or HAP and is strong in tensile strength and green in color for easy application.

Green Sand Parting
Our KwikDraw product line is formulated as an economical green sand release agent that demonstrates excellent release characteristics with all types of automated molding machines.
Our product line includes KwikDraw HiSolids, a highly concentrated premium green sand release agent that gives improved green sand casting surfaces with reduced incidence of sand erosion, scabbing and other surface gas defects.
KwikDraw HiFlash is a low viscosity green sand release agent with a very high flash point hydrocarbon designed for high production molding machines.


Powder Core Pastes
Our powder core paste, PowderWeld, is supplied as a dry powder designed to be mixed with water to the customer desired consistency/viscosity.
PowderWeld resists water pickup in stored molds and resists metal penetration along seams and can be utilized with all types of resin systems.

"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."

- JD Schmidt, QA Manager, Ohio Ferrous Foundry

“Ashland Foundry & Machine Works and Weatherly Casting are grateful for the partnership in our working relationship with Weaver Materials.  Weaver has helped us maintain pricing and avoid increases in a volatile market.  Weaver has always kept us in supply of material when markets dictated shortages/allocation status.  If Weaver was not in our vendor pool daily production ability would have been negatively impacted.  Weaver is also technically able to review our foundry processes and make suggestions to either achieve a cost savings or process improvement.  I am looking forward to a continued collaboration between the Weaver team and my locations.”
