What is a No-Preheat Product?

For a preformed thermoplastic product that does not require preheating, heating to the point of bonding to the road and proper embedding of factory-installed surface elements occurs in a controlled manner only when the pavement surface is at ambient temperature when the product is placed on the pavement. Preheating the pavement for a preformed thermoplastic pavement marking that does not require preheating does not offer the applicator an advantage. In fact, it creates an unnecessarily difficult situation for the applicator, as there is a good chance the factory-installed surface elements will be over-embedded resulting in poor anti-skid and/or retroreflective properties.

What is a Preheat Product?

For a preformed thermoplastic product that requires preheating of the road surface, heating to the point of bonding to the road and proper embedding of factory-installed surface elements (glass beads and/or skid resistant material) occurs in a con- trolled manner only when the pavement surface has been pre-heated to a temperature of approximately 300°F. Additives are used in the product formulation that impede the sinking of the factory-installed surface elements during application and also act as an insulator that inhibits heat transfer when the surface of the material is heated. For this type of material,
if the pavement surface is at ambient temperature (i.e. not preheated) either:
a) sufficient bond will not be achieved with optimal embedment of factory-installed surface elements; or
b) although unlikely, sufficient bond could potentially be achieved by severe overheating of the material surface resulting in heavy charring/damage and less than optimal anti-skid and retroreflective properties In other words, unless the road surface is preheated to a certain temperature the result is certain to be either a poor bond between the material and the
