[Surface Treatment Solution Case] Improved Extrusion Molding Troubles of Elastomers!
MRS coating
Prevent eye discharge when extruding elastomers. Reduce defects with mold release surface treatment!
■Concerns We received an inquiry from a customer who is prototyping a new elastomer extrusion product. They wanted to resolve the issue of unstable production due to adhesion to the extrusion mold. ■Background for Coating Adoption Initially, the adhesion was so severe that it was impossible to form the product, but after adopting our surface treatment, they were able to prevent adhesion to a degree that allowed production. However, during continued mass production, it was discovered that defects due to the adhesion of eye mucus occurred after about a month of use. ■Selected Surface Treatment 'MRS Coating MRS-102' ■Selection Process and Effects To further address the defects, we proposed MRS-102. Although eye mucus did occur during testing, it did not adhere to the mold and could be easily removed, which helped suppress the occurrence of defects, allowing for continuous use for six months. *For more details on the adopted 'MRS-102', please refer to the materials or contact us.*

basic information
◆MRS Coating◆ (Silicone Coating) 【Series Features】 ■MRS-102 Maintains effectiveness even after cleaning with solvents ■MRS-014 Preserves shapes like the thinness of blades and textures ■MRS-004 Heat resistance exceeding 200°C, comparable to fluororesin (Release properties remain intact even after 16 hours at 350°C) ■MRS-200 Can be processed with resins and rubber products at processing temperatures below 80°C ■Release properties (non-stick) and excellent cleanability → The smooth surface makes it easy to wipe off dirt, and even when cleaned with solvents, the release properties change very little *Based on our durability tests 【Introducing a part of the lineup】 - Release properties (non-stick) + solvent resistance → MRS-102 - Release properties (non-stick) + film hardness (9H) → MRS-014 - Release properties (non-stick) + heat resistance (300°C) → MRS-004 - Release properties (non-stick) + low-temperature processability (below 80°C) → MRS-200 - Release properties (non-stick) + slip properties → MRS-003 *For more details, please refer to the materials or contact us.
