Marktiva Reflective Glass Beads (1 LB) — Road Marking
Marktiva’s Reflective Glass Beads come in a compact 1 lb bag designed for road marking, curb paint, and traffic applications. The beads are noted for uniform size and clarity, with roundness exceeding 95%. Airport-quality beads are larger than standard options, delivering enhanced retroreflectivity especially under wet conditions. The beads’ refractive index is reported at 1.5+, contributing to strong nighttime visibility. They’re also marketed to extend the life of markings when used on top of paint or epoxy.
Marktiva Airport Quality Glass Beads — 10 lb
This 10 lb airport-quality option from Marktiva emphasizes size uniformity and high retroreflectivity in wet conditions. The larger bead size is designed to maximize visibility from headlights and other light sources, which may help illuminate hazards and capture attention on road markings, driveways, and airport facilities. A refractive index of 1.5+ supports strong nighttime reflectivity, and the product is intended to extend marker life when applied over paint or epoxy coatings.
NaFurAhi Reflective Glass Beads (25 Lb)
NaFurAhi offers a 25 lb bag of reflective glass beads designed for road marking, curb paint, and crosswalks. These Type 1 beads align with AASHTO M-247 standards and meet federal and state specifications. They support inter-mix for texture or drop-on applications. The beads feature a broad mesh range (20-325 US Mesh, 45-850 microns) and a refractive index of at least 1.51, contributing to strong retroreflectivity and multilayer compatibility for highway-grade markings.
Patelai Reflective Glass Beads (Powder/Beads) 4.4 Lb
Patelai’s 4.4 lb set includes both powder and bead forms. The package notes two packs of 2.2 lb each to meet varying usage needs, making it suitable for both spot applications and larger top-coating tasks. The beads are designed to vigorously reflect light from headlights to improve nighttime visibility, help illuminate hazards, and extend the life of markings when used atop paint or epoxy. They are portable for on-site use and storage at home or job sites.
Marktiva Reflective Glass Powder (10 Lb)
Marktiva’s 10 lb bag emphasizes AASHTO M-247 DOT Type 1 highway beads with a sand-like texture. The product meets federal and state specifications and supports either inter-mix for texture or drop-on applications. Specifications include a bead size range of 20-325 US Mesh (45-850 microns) and a minimum roundness of 80%, with a refractive index of at least 1.51. This powder form offers high reflectivity when used as a top coating on paints, adhesives, or epoxies, contributing to nighttime visibility and safety.
Buying Guide: Key Purchase Considerations
When selecting glass beads for road marking paint, consider the following dimensions to match your project needs:
- Bead Type and Standards: Type 1 beads meet federal and state specs; ensure compatibility with your regulatory requirements for road markings.
- Size and Roundness: Larger, rounder beads generally provide better retroreflectivity in wet conditions and higher nighttime visibility.
- Refractive Index: A higher index (around 1.5 or more) indicates stronger reflection of headlight beams.
- Application Method: Inter-mix for texture or drop-on methods affect texture and reflectivity; plan according to paint type (water-based, epoxy, oil-based).
- Bead Color and Clarity: Uniform color and clarity reduce patching and improve uniform reflection across markings.
- Package Size: Choose bag size based on project scope; some bundles include mixed forms (powder plus beads) for flexibility.
- Storage and Handling: Consider packaging that facilitates on-site use and long-term storage, especially for larger projects.
- Compliance and Safety: Ensure beads meet local DOT or highway standards for the intended jurisdiction.
Across these options, the common aim is to maximize retroreflectivity, durability, and safety of road markings under varied lighting and weather conditions. Compare bead size, the stated refractive index, and compatibility with your chosen paint system to select the best fit for highways, parking facilities, and airport runways.
