Choosing the Right Cold Applied Plastic (MMA) Applicator
Cold Applied Plastic (CAP), also called MMA after the methyl methacrylate resin, is the highest-durability ATS 4110 longitudinal marking material. It cures cold by chemical reaction (no heat, no waiting for paint to dry), bonds to both sprayed seal and asphalt, and lasts five to eight-plus years on heavy-traffic asphalt. CAP is the right call for signalised intersections, bus lanes, high-wear corners, and any council or contractor work specified to ATS 4110 Clause 5.11, AS 4049.4 and APAS 0041/3.
Walk-behind 1:1 plural-component. The Graco LineLazer V 200MMA 1:1 HP Reflective is the production walk-behind CAP unit, available as 1-gun (17Y271) or 2-gun (17Y512). The Innovative Flow Divider splits the resin and catalyst at exactly 50% each, the Fusion ProConnect Gun mixes the two streams at the gun (not in a pre-mix pot, so working pot-life is not the constraint), and the Air-Purge clears the mixing chamber on shutdown. RAC 5 SwitchTips clear tip clogs without unbolting the gun. 3,300 PSI / 228 bar / 22,800 kPa across the 200MMA range. Buyers who want the gun bundled in the unit order the configuration variants 17Y234 and 17Y513.
Self-propelled 98:2 catalyst-rich. The Graco LineLazer V 250MMA 98:2 HP Reflective Self-Propelled (17G589) runs the same HP Reflective platform with a 98:2 ratio (98% resin, 2% catalyst), petrol drive, and pressurised bead delivery. The 98:2 system suits long-line CAP runs where the operator needs ride-on speed and a single resin-dominant feed. Same ATS 4110 / APAS conformance as the 200MMA range.
Glass beads are required, not optional. ATS 4110 5.11 mandates that CAP be used in conjunction with glass beads complying with Clause 5.12 (Type B-HR, C-HR or D-HR per APAS 0042). Where CAP is applied as a structured pattern (e.g. ribbed audio-tactile), coverage must be 60-80% with maximum height 4 mm. For audio-tactile CAP: white is retroreflective with intermix and surface-applied beads; matt grey or matt black are NOT retroreflective and carry no beads. Bead retroreflectivity targets per ATS 4110 Annexure B Table B1b: white longitudinal markings 350 mcd/m squared/lx within first 30 days, 200 mcd/m squared/lx between days 365-395, intervention required below 150.
Sprayed seal AND asphalt, both in one unit. Unlike thermoplastic (which struggles on raw concrete and needs a primer pass on most concrete) and waterborne paint (whose pavement bond is not a long-life solution on heavy-traffic asphalt), CAP/MMA bonds to sprayed seal AND asphalt directly. ATS 4110 5.11 explicitly permits CAP for both surface types. That makes the 200MMA unit the most versatile durable-marking machine in the GO range: one rig, both surfaces, multi-year service life.
