MS-143XD

MS-143XD is a versatile release agent and dry lubricant using a rapidly drying, VOC exempt carrier solvent. It contains a high lubricity, low molecular weight PTFE fluoropolymer designed not to interfere with post-finishing operations. It provides efficient, consistent release of molded parts and minimizes slip-stick; it is non-flammable, non-ozone-depleting, non-migrating, non-staining and RoHS2/RoHS3 compliant. It releases plastics, rubbers, resins, phenolics, acrylics, polycarbonates, urethanes, polystyrene, nylons and elastomers with virtually no transfer, and is used as a dry lubricant on metal, ceramics, glass, elastomers, rubber, polycarbonates and wood. It is available in different PTFE concentrations; the standard 3% is recommended for most applications.

Typical Properties

• Fluoropolymer; white particle suspension; slight odour
• Specific gravity (20 °C) 1.6 g/mL; flash point none

Use

• Clean the mold surface mechanically (bead blasting or steel wool), then chemically; remove all previous release agent
• Mix the product before and continuously during use; spray "wet" with fine mist equipment onto a mold surface below 50 °C
• Allow the solvent to evaporate completely before molding; reapply one coat when release becomes hesitant
• Optional fused coating: heat the surface to 305–316 °C and hold for 5–10 min
