TYPE IIA Drop on Glass Beads for Brazil
TYPE IIA Drop-on Glass Beads for Brazil
Product Overview
OMNI TYPE IIA Drop-on Glass Beads are specially designed for road marking applications in the Brazilian market. Manufactured from high-quality soda-lime glass, these transparent spherical beads are applied directly onto freshly painted road markings to enhance nighttime visibility and retroreflective performance.
With excellent roundness, consistent particle size distribution, and reliable optical properties, our glass beads help reflect vehicle headlights toward drivers, improving road visibility and contributing to safer driving conditions.
Designed for compatibility with different road marking materials, including thermoplastic, cold plastic, water-based, and solvent-based paints, OMNI glass beads provide reliable performance for highways, urban roads, parking areas, and other traffic marking projects.

Key Product Features
1. Perfect Spherical Geometry
Each glass bead maintains a precise spherical shape, ensuring optimal light reflection and maximum retroreflective performance. Consistent geometry helps direct incoming light back toward its source, significantly improving road marking visibility and driver safety, especially at night.
2. High Refractive Index Structure
Manufactured from specially formulated soda-lime glass, our glass beads offer excellent optical properties and light refraction. Their optimized refractive structure enhances brightness and visibility under vehicle headlights, contributing to safer nighttime driving conditions.
3. Controlled Particle Size Distribution
Available in multiple particle size specifications, our glass beads feature uniform particle distribution and a carefully controlled grading system. This ensures consistent coverage, optimal embedment depth, and reliable retroreflective performance in road marking applications.

Application Method
TYPE IIA Drop-on Glass Beads are applied by spraying onto freshly applied road marking paint or thermoplastic materials. The beads partially embed into the wet marking layer, allowing their exposed surfaces to collect and return incoming headlight beams.

Recommended Application Process:
Prepare the road surface and ensure it is clean and dry.
Apply road marking paint or thermoplastic material evenly.
Spray glass beads onto the wet marking surface using suitable application equipment.
Allow the coating to cure according to the material manufacturer's instructions.
Inspect bead distribution, embedment, and retroreflective performance.
Recommended Embedment Depth: Approximately 50–60% of the bead diameter, subject to the coating system and project requirements.
Reference Application Rate: 300–400 g/m², subject to project specifications and field testing.
Main Applications
Highways & Expressways: Enhances nighttime lane visibility and road safety.
Urban Roads: Improves visibility of lane dividers, crossings, and traffic symbols.
Airport Pavements: Supports visibility of pavement markings in low-light conditions.
Parking Areas: Provides reflective properties for parking lines and directional markings.
