Reflective Glass Powder 1 LB — Marktiva
Features: Reflective “Powder” Type 1 beads. These are the same reflective glass beads used on highway lines. Inter-mix or drop-on applications. Bead size: 100-200 US Mesh, Mil-Spec 10/11. This product is best for small projects, test patches, or when you want to experiment with texture before committing to larger batches. Best for contractors or DIYers who need ready-to-broadcast options and simple integration with water- or oil-based paints.
Best for: Small-scale markings, pilot tests, arts and crafts with road-themed elements. This option provides highway-grade bead quality in a compact package. Caution: Smaller bag means limited supply for large-area coverage; plan reapplication accordingly.
Reflective Glass Powder 10 LB — Marktiva
Features: AASHTO M-247 STANDARD DOT TYPE 1 highway beads. Sand-like texture. Inter-mix or drop-on applications. Bead size ranges 20-325 US Mesh, 45-850 microns. Refractive index >= 1.51. High quality and performance for top-coat use on paints, adhesives, epoxies, or industrial tape. Best for: Projects requiring higher volume and long-term nighttime visibility in road markings, parking lots, and curbs. Caution: Larger bead set may require compatible application equipment for uniform distribution.
Why selected: This size range and DOT Type 1 classification align with typical highway marking standards, making it suitable for professional-scale projects where retroreflectivity is critical.
Reflective Glass Powder for Traffic Paint & Epoxy — Roly Poly
Features: MAXIMUM reflectivity when broadcast onto wet paint or epoxy coatings. Type 1 highway-grade beads suitable for parking lots, curbs, driveways, crosswalks, and industrial settings. Compatible with line striping equipment and bead dispensers. Best for: Professional striping crews and property managers needing bright nighttime markings immediately after application. Caution: Best results occur when broadcast onto fresh coatings; timing and technique influence reflectivity.
Reflective Glass Beads 1 LB — Roly Poly
Features: High-quality, uniform, round beads (95%+). Airport-quality glass beads with refractive index 1.5+. Increases nighttime visibility and durability. Best for: Bead-dense surfaces where maximum retroreflectivity is needed, especially in wet conditions. Caution: Larger beads can be less uniform if not dispersed properly; ensure even distribution to avoid hotspots.
Reflective Glass Powder 25 LB — Marktiva
Features: Made of tiny glass beads for reflective markings on roads, highways, curbs, concrete, parking lots, and airports. Applied to water-based paints, oil-based paints, alkyd coatings, hydrocarbon thermoplastics, methyl methacrylate, and epoxies. Best for: Large-scale projects requiring substantial material, such as long road corridors or multiple parking lots. Caution: Bulk handling requires storage planning and adequate mixing to ensure consistent dispersion.
Buying Guide
What should you consider when choosing a reflective additive?
- Application method: Broadcast-on-top vs. mixed-in. Broadcast-on-top generally yields maximum retroreflectivity with fresh coatings.
- Bead type and standard compliance: DOT Type 1 highway-grade beads meet highway marking expectations; ensure compatibility with your coating system.
- Mesh size and refractive index: Finer beads may spread more evenly in paint, while larger beads boost reflectivity in wet conditions; higher refractive index improves night visibility.
- Project scale: Small DIY projects suit 1 lb bags; larger contracts benefit from 10–25 lb bags for cost efficiency.
- Coating compatibility: Check whether the additive works with water-based paints, oil-based paints, epoxies, or other coatings you plan to use.
- Equipment compatibility: For professional line striping, verify that the product works with bead dispensers and line-striping machines.
Frequently Asked Questions
- What is the main difference between glass beads and glass powder?
– Glass beads are solid spheres that remain exposed to light, while glass powder is finer and can be broadcast into or onto coatings to create a reflective layer. - Can I mix reflective beads into paint?
– Some products are designed for mixing into coatings, but others are intended to be broadcast on top of wet paint for maximum brightness. - Is highway-grade (Type 1) reflective material necessary for my project?
– For formal road markings, Type 1 highway-grade beads meet common standards; smaller private lots may still benefit from similar retroreflectivity without formal certification. - Will reflective additives affect paint durability?
– When used as directed, these additives typically enhance visibility without compromising coating performance; follow manufacturer guidelines for best results. - How do I choose between 1 lb and 25 lb bags?
– Start with a small bag for testing; scale up to 25 lb for larger projects or ongoing maintenance depending on area coverage needs. - Are these additives safe for indoor use?
– Reflective beads designed for road markings are generally safe for indoor use on compatible coatings, but verify any ventilation or handling instructions on the product data sheet.
