Mold Sealer

Prevent Demolding Defects with a High-Quality Mold Sealer

开始一个新的绿色合成工具first time should be a satisfying experience. But when parts stick even with a high-qualitymold release agent, it can leave you feeling exasperated. You applied the release correctly, and the mold is new. Parts shouldn’t be coming out with defects.

Leave your frustrations behind when you first apply a mold sealer! Properly sealing your mold surface before applying a mold release agent creates a protective barrier that bonds to the surface and fills in the microporosity. This barrier provides an ideal surface for mold release bonding. Get in touch with our experts today to learn how our mold sealants can improve your production process!

KantStik Sealer 1.0

Mold Sealers Make Your Industrial Molding More Efficient

While you may be using a mold release agent to prevent demolding issues, such as sticking and part appearance, you could be missing an important step if you’re not using a mold sealer first. The reason? Molds expand and contract during the thermal changes of each production cycle, causing extremely small cracks to form. Eventually, the resin begins to penetrate these cracks, resulting in part and mold damage.

But when you useKantStik Sealer 1.0before your release agent, it fills in that microporosity to create a smooth, even surface for your mold release and resin. The results are molded parts that release more easily and without defects. This outcome makes your molding operations more efficient and decreases scrap parts.

Improves the Molding Process

KantStik Sealer 1.0 is a polymeric coating for new or reconditioned tooling. It seals non-porous surfaces with a durable and resilient coating. You can use this sealer as a base coat for any sacrificial or semi-permanent mold release agent to impart a new, strong, and chemically resistant carrier. This barrier allows you to use less mold release and still see complete molded parts that release easily.

Reduces the Number of Defects

When molds have microscopic pores that aren’t filled in with a mold sealer, the mold release and resin that you use fill those pores. When you demold your products, those pores appear as defects rather than the smooth, clean surface you want. But when you use a mold sealant first, it fills in those pores to create a smooth surface to which the mold release and resin can bond. The result is fewer defects and less scrap.

Releases Parts Easily

When combined with a high-quality mold release,B0B体育app下载, andrust preventative, mold sealers help create a surface that allows resins to fill in the most detailed areas of the mold and not the extremely small cracks. When it’s time to release the product, it comes out easily with no significant build-up on the finished part. In addition, you won’t have to reapply the mold release as frequently when using a sealer.

As a base coat for the release agentFRP-SC—a premium semi-permanent mold release—they could create precise molded parts in less time. They used two coats of KantStik Sealer, applied 15 minutes apart, by wiping it on the mold surface and leaving it on the surface to bond, which had a final cure time of 30 minutes. Then, they apply a coat of the FRP-SC mold release by wiping and leaving it on for a cure time of 30 minutes.

After four coats of the release agent, they apply a final coat and wipe it off while it’s still wet. These efforts allow the manufacturer to achieve 20% more releases in the same amount of time with no streaking and no buffing necessary! Since the active ingredients bond to the surfaces instead of the towel, the release adheres to the tool and creates a finished product without sticking.
