HISTORY OF MMA
(METHYL METHACRYLATE)
Originally used in Canada in the late 1950's to provide LONGER LIFE to road markings and to allow for applications at LOWER TEMPERATURES than traffic paint. MMA began as an extruded material. Over time the application process has advanced into a SPRAY FORMULATION. First came the 1:1 system and now the end goal of 98:2 IS HERE!
STAGE 1
EXTRUDE MMA
Advantages
More durable than traffic paint
Can be applied at low temperatures
While laborious and inefficient, this method is something most anyone can perform
DISAdvantages
Inefficient and slow, does not provide “pretty markings”
Massive amounts of waste, drives up cost
High profile on ground, susceptible to plow damage as a result
STAGE 2
1:1 SPRAY
Advantages
More efficient than the extrude application method which reduced waste and made application process faster
More detailed work made possible on applications that have more than simple rectangular stop bars and stencil arrows
Cost to customer could be brought down from extrude
Durability achieved at less mil thickness meant less plow damage
DISAdvantages
Still had considerable waste due to three part activation process
Machine was relatively complicated to use and resulted in down time
Lengthy learning curve
Mistakes in operation lead to considerable repair expense
STAGE 3
98:2 SPRAY
Advantages
Essentially zero waste
Increased speed + efficiency of application
Greatly reduced setup and teardown time
Liquid BPO is much safer than powder used in 1:1 and extrude
Greatly Improved reliability - user friendly
Faster, more reliable cure, even at low temperatures
TBL Durables has the only functioning 98:2 walk behind machine.
