Polymodifed Hotmelt Adhesive BP05 Per 25Kg Block

SKU: R4000

Sale price£30.00


Adhesive polymer modified hot melt for use with the 3M290's, Aluminium or Stainless Steel Pedestrian Crossing Studs and our Safemark Hotmelt Temporary Road Studs.

Supplied in blocks, it has an indefinite storage life in cool conditions.


It is advisable to break the adhesive block into smaller pieces for more efficient heating. Using suitable application equipment capable of maintaining initial adhesive temperature, the adhesive is heated to 160-180 C. This is the optimum temperature for both adhesion and application properties. Lower temperatures will reduce adhesion and make it more difficult to handle. Higher temperatures maintained for longer periods may damage properties and could lead to combustion

Surface Preparation

Ensure the road surface is dry, free of dust and loose material. It may be necessary to “tamp” the surface in order to flatten any prominent crowns etc. for application onto surface dressing. Oil, grease or salt deposits should be removed either mechanically or chemically. Studs should not be laid over loose detritus, mud or similar extraneous matter or over old flaking marking of paint or thermoplastic material. If the road surface is at a temperature of less than 5 C, or if it is wet, it should be warmed carefully by a road heater so that, when the material is laid, the surface temperature is above 5 C and the surface is dry.


After surface preparation, the adhesive should be dispensed from the heating unit directly onto the road surface in order to maintain correct contact temperatures. Oil jacketing or other heating at the dispensing head is recommended in order to achieve this. Sufficient adhesive should be applied onto the surface to cover an area slightly larger than the stud base. The stud should immediately be placed on to the adhesive, ensuring an edge seal around the entire stud. It is better to apply too much adhesive than not enough. Studs not bedded on the entire base surface area will be subject to non-uniform loading which may lead to failure. Applications to surface dressed, or other surfaces of macro - texture may require two applications of adhesive in order to fill the interstices. The stud should float on a layer of adhesive, not rest on the road surface or crown of any prominent chipping. Subject to ambient temperature, the studs should be allowed to set for 30-120 seconds before exposure to traffic. Complete resistance to rotational movement of the stud by hand indicates it is ready to be trafficked.
