Which is the Best Mold Release Agent for My Product?
Production delays from sticking parts and excess build-up on your molds can result in frustration and lost revenue. However, when you choose the right mold release agent for your product, you can reduce many of these common production challenges, leaving you with perfectly released molded products.
Here at Stoner Molding Solutions, we are experts at helping you mold more parts in less time. Our complete line of mold solutions is specially formulated for superior quality and consistent performance. By knowing your industry and the product you need to mold, we can help you select the appropriate mold release for you.
Composite Mold Release Agents Maximize Production
The composite industry relies on producing superior parts while reducing waste to maximize production and profits. For this industry, Stoner Molding Solutions offers both sacrificial and semi-permanent mold release products. We have both options available depending on which polymer you are molding: epoxy, phenolic, polyester, or vinyl ester. Check out the list below for just a few recommended products, but reach out to one of our product experts for tailored suggestions.
- Epoxy Polymers
- Phenolic Polymers
- Sacrificial – Stoner E474 Zinc Stearate Mold Release is a dry-powder, heavy-duty release agent that allows molded parts to be post-decorated. It’s ideal for testing new molds, and the anti-stick film allows for easy part removal from molds.
- Semi-Permanent – G472 XK-22 Lv. 1 Mold Release Liquid and G471 XK-22 Lv. 5 Mold Release Liquid are premium high slip release solutions for resins that require a post-cure. Both are suggested for resin transfer molding or vacuum bagging since they have a maximum molding temperature of 752 degrees Fahrenheit.
- Polyester and Vinyl Ester
- Sacrificial – Kantstick LM 35 Concentrate Mold Release is a versatile and practical release agent in a water-based system. It’s beneficial in the manufacture of friction parts, like brake shoes.
- Sacrificial – P313 Release & Paint Mold Release allows products to enter a post-painting phase, decreasing downtime between steps.
- Semi-Permanent - P59301 KantStick Cure Fast has a built-in sealer, so only three coats are required with a 15-minute cure time, maximizing product release on polyester polymers.
- Semi-Permanent – G494-QB Release, designed for polyester or vinyl ester resin systems, doesn’t require buffing, allowing for a quick molding process. For finished parts that are gel coated, G494 can also be sprayed.
Releases for the Polyurethane Industry Reduce Scrap Parts
When you need a high-quality polyurethane molded part, use Stoner Molding Solutions’ products to reduce scrap parts by selecting the right release agent for the type of product being molded. Stoner products allow you to produce more parts every day in your molding operation by preventing sticking and cracking.
You can use the following list of products as a reference, depending on the material being molded. Need more information? Feel free to give us a call for personalized service!
- Cast Elastomers
- TDI – E236 Urethane Mold Release is an aerosol, silicone-based mold release perfect for various casting resins. The simple application allows parts to release quickly and easily, preventing sticking, so you have less waste.
- MDI – Use Stoner’s G402 Nix Stix X-9032A for MDI’s. A focused spray pattern for precision coverage means fewer sticking parts.
- Rigid Foam – To use P160 Polyurethane Release properly, apply a thin coating of this non-VOC formula to release a high volume of parts very quickly.
- Flexible Foam – M883 Poly Out Polyurethane Release is a solvent-based wax suspension for flexible mold foam. It gives the molded product an open-cell finish while reducing build-up on the molds.
- Integral Skin – M800 Polyurethane Release is ready to use and heavy-duty designed for low-temperature molding. Apply a thin coating for integral skin to release wholly and quickly.
- Polyisocyanurate – P229 Polyiso Release is optimized for polyisocyanurate insulation release. Insulation boards release fully when this product is applied to side plates and mold surfaces.
Rubber Molding Solutions Increase Tool Life
There is no doubt that rubber is a versatile material to manufacture a wide range of parts. Yet, its flexibility creates some production challenges since the compounds in rubber can damage mold surfaces. When you use Stoner Molding Solutions’ products, you can help protect the life of your molds.
We have different cost-effective solutions for natural and synthetic rubbers, with some suggestions on the list below. Talk with our experts today to find out which product is right for your manufacturing operation!
