DOWSIL™ MS-4002 Moldable Silicone A&B Kit

  • Overview

    High thermal stability; Comparatively high hardness and low surface tension; Smooth, low-tack, plastic-like surface; Optically clear, high light transmittance, with lower haze – Moldable Optical Silicone.

    High Light Transmission
    Low light attenuation coefficient

    Lighter Than Glass
    High Shore A hardness; with excellent surface features replication

    Proven High Performace
    Award winning moldable optical silicone

    This award winning moldable optical silicone is a medium viscosity, high Shore A hardness, fast heat curing optical molding resin for producing optical parts with good resistance to environmental aging. It has a smooth, low-tack, plastic-like surface and enables the molding of complex, finely detailed optical parts and secondary lenses. It remains relatively soft after injection molding, with high elongation capability for easy demolding of complicated parts, such as those designed with a combination of thick and thin areas (e.g., lens clusters). After demolding and post-curing, it reaches its final mechanical properties and produces hard and tough optical parts. It shows enhanced stability of optical performance upon high heat, high humidity and UV exposures, meeting the most demanding requirements for outdoor lighting applications

    This two-part, 1:1 ratio material features

    • Optically clear, high light transmittance with lower haze
    • High thermal stability
    • Opportunity for reduced cycle time due to reduction in scorch time
    • Meets UL-746C-f1/UL-94 certifications for outdoor applications
    • Complements the existing DOWSIL™ MS-10XX Moldable Silicones

    APPLICATIONS

    Injection molding for secondary optics, lens clusters, light pipes, light guides and free form collimators.
