Buyer's Guide About Polyurethane Release Agent

Meiyahg uses the strongest release coating designed for processes that demand a release coating to withstand the most aggressive elastomer chemistry. Therefore, our mold release agent for polyurethane is preferred by industries all around the world to make sure cost-effective, efficient, and high-quality release of their molded parts.
Release properties of our polyurethane release agent work with all cast elastomers, rigid foam, flexible foam, visco-elastic foam, and integral skin foam while the coatings provide a perfect fit for all mold surfaces such as steel, aluminum, epoxy, urethane, and fiberglass. They are designed to provide reliable release characteristics without building up on the mold surface. The Reduced buildup will cut down on cleaning time and frequency as well as reduce rejection rates due to poor surface finish or failed release. We offer release agents for Glossy, Matte, and Satin surface finishes. Our PU mold release agents are chemically engineered to develop a non-carbonizing and heat-stable film which wets the mold surface evenly to ensure long manufacturing rounds without compromising the urethane skin. Meiyahg offers both water and solvent polyurethane resin release agent with 100% non-flammable, low VOC, and low odor.  The non-silicone mold release agent for polyurethanewill not transfer when paint and adhesives are applied during post-molding operations. Our chemical release agent do not contain solvents, is non-flammable, odorless, and produces multiple releases.

Our Polyurethane Release Agent Feature

The major concern most molders have is material contamination by the mould lubricant, but our Polyurethane release agent are chemically inert and bond to the mold or tooling surface for superior, contamination-free release characteristics without transfer. Our exclusive formulas resist transfer and not ever buildup on parts and tooling as they are non-oily, non-dusting, and dry clean on the substrate. Meiyahg specialized Polyurethane release agents are exclusively designed in a way that they can  provide our customer with the following benefits:

1. Superior part release: Meiyahg specializes in Polyurethane release agent product formula that provides multiple releases per application and optimized part quality.  So, you will get reduced downtime with fewer defects irrespective of the polyurethane molding process.
2. Minimal Transfer: Meiyahg customized polyurethane release agents are formulated to form a durable, even and a robust film on the mold surface that ensures minimal transfer to the part. This feature ensures that any secondary operations, such as gluing or painting, do not get affected which also reduces the need for time-wasting clean-up.
3. Lower defect rates: Our formulations are flawlessly balanced, ensure durability, provide optimum surface slip, and minimal build-up.  Therefore, the molded parts manufactured more consistently and with a high level of efficiency.
4. Higher quality parts: Meiyahg ’s specialized PU mold release formulations exceed all standard urethane molding requirements. Therefore, the result is a product line with lower build-up on tooling and almost non-sticky, greasy residues ensuring greater quality parts and inferior rejection rates.
5. Less downtime / Higher efficiency: Our polyurethane release agent are specially formulated to maximize releases per applications while minimizing mold fouling. This feature ultimately leads to less time required to apply mould release agents and less time to clean up the remains that lesser quality release agents leave behind.
6. Water-based, no/low VOC emissions, cleaner safer working environments: The states which have strict VOC regulation and air quality authorization protocol or the companies who prefer products that are safe and have no odor, Meiyahg has created a collection of polyurethane release agents that are water-based, VOC free or low VOC. Furthermore, our products not only provide a solution to lower VOC output but these excellent products also ensure optimal performance just like the solvent-based products you have used.
7. Optimized surface finish:  Sakurai Polyurethane release agents are designed to offer a variety of surface finishes.  Its high gloss, matte, or 100% dry finish you require, we have specialized formulation in each category to meet your needs. Our solutions will meet your surface finish requirements without leaving any greasy and oily residues behind like the other mould release agents do.
8. Less waste and Cleaner final products: Our Mould Release Spray are designed to give your products a cleaner separation, so as a result, there will be fewer damaged raw materials throughout your operations. When you use PU molding, your end product will have less residue and proper cleanliness, which will result in good appearance and functionality.
9. Prevents pin-holing: A major concern for plastics and polyurethane molders is Pin-holing. Our release agents are perfected to adequately wet the desired surface to form a durable and even coating that will prevent pin-holing, cracks, knit lines, voids, and surface indiscretions in the polyurethane.
10. Longer mold life: PU injection molding helps molds to last longer without required replacements. As when you are using our polyurethane release agent, your molds do not constantly undergo cleaning, and the separation process is not as rough on them since undesired bonding does not occur.

So, you get:

• Cleaner molds
• Less downtime between molds
• Water-based options available
• Little/No VOC emissions
• Promotes excellent surface finish
• High gloss or shiny finishes available
• Multiple releases per application
• Reduced buildup on molds and tooling
• Will not cause pin holing
• Nonreactive coatings which will not damage PU materials
• Higher active resin content that improves release characteristics

Plus Meiyahg ensures that:

• Products are sold directly to factories
